Animating 3D People with Animator

The source for the outer shell of the characters is, as mentioned above, the 3D warehouse ("3D People").
Most of the time I use models that are already divided into the moving body parts ("Rigged").
For example: Cronoz-artes Graphic Design, Brazil: https://3dwarehouse.sketchup.com/by/CRonoz?login=true#
I modify and combine the body parts in order to adapt them to my representation goals and movement sequences.OK - I just had to try so I went to the site in your link a downloaded one of his models and imported it into SketchUp. Then I went to the outliner and modified the names of things a little (see outliner image below) so that I could select them better in Animator. Then I played (just a little and kind of poorly) to see if I could animate the model using Animator. Click on the gif file below just to see my start. Yes, it is not all that good but my objective was to see how hard it would be to animate a character like you did but using Animator (I have not used it for a couple of years).
I am still very interested to see Anton comes up with in his update to MSPhysics.
My goal with the whole discussion (which was inspired by Nuke's thread on the SketchUp forum) was to see if a character could be animated within SketchUp in coordination with other animations. I was hoping Fredo6 might also participate in this thread.
While I think it is possible I see some real challenges:
- First and foremost is the ability to create characters/people in a format that can be animated smoothly and retaining things like clothing.
- The smoothness of animating the character
- While animating a character to run/walk is possible (IMO) it might be much more difficult to animate the character to do other things like sitting down on a chair or interacting with other characters/objects
- I think it would be really neat if animated characters from other sources could me imported and combined with other animations within SketchUp
- I have not yet tried to render an animated character but based on the sophistication created and animated in SketchUp, it might be difficult to achieve a quality render.
I have probably reached/surpassed by capabilities on this topic, but again, I think this environment could be of great value to people using SketchUp and hope we get some good interest and comments.

I did't test it but it's free
Isuppose you can export in some 3D formats compatible with SU...https://www.youtube.com/watch?v=JFuYJDpwYc8&feature=youtu.be

Dave,
You've made good progress towards your goal, and educated me in the process. I, um, hadn't discovered Outliner yet.
So you've encouraged me to follow your lead in this direction.Pilou, thanks for the link to Cascadeur! It looks great. Not available for Mac yet though, so that will slow me down. Perhaps this is a good enough reason to fire up Windows again.
If either of you guys use Cascadeur I'd love to hear your reviews.
Good thread Dave, keep it coming.
-
So I really wanted to try Cascadeur, but it's Windows only for now. I looked in to installing Windows on my Mac, but just don't have the stomach for all the bother at the moment.
This reminded me of a Mac 3D app that I hadn't looked at in a couple of years.
It's $100 to purchase, and has a free unlimited time trial that offers all features except saving projects.
Here are some YouTube tutorials which discuss animation in this software.

It will export in DAE, FBX and some other formats. So you should be able to pose a character in Cheetah and bring it in to SketchUp. To add an animated character to a SketchUp scene I guess you'd have to use the video editor method.
So if you wanted to create your own character animations, and not have to rely on Mixamo stock animations, and are on a Mac, Cheetah might be helpful.
To the best of my understanding, Cheetah is similar to Blender, but is more accessible to novices. Sounds right for me, so I'm going to dive in to it.
I know that Dave is hoping to animate directly in SketchUp, so this is kind of off topic, but hopefully helpful to somebody.

@ Nukeman: It should be an easy way to get the CRonoz characters into a T-pose. Usually you can download the figures in a straight basic position and there are small components built in as pivot points for the body parts (only visible in transparent styles).
@ ntxdave: Very good first result and definitely the right approach. Fredo's Animator is very suitable for timeline and K-frame animation. Smooth and pliable skin and clothing on the joints is almost impossible in SketchUp. I tried that with an orca animation with MSPhysics and had to invent profound, elaborate tricks: http://sketchucation.com/forums/viewtopic.php?f=323&t=68498#p626651
In order to achieve smooth movements and transitions, Fredo's Animator provides curves for the process.
Walking, sitting, getting up and moving on is actually a complicated process. It took me a long time to do this ...To let animated characters from other programs act in SketchUp, I consider the current state of the SketchUp functions to be impossible. It would be conceivable that Fredo could program an exchange of animation data between Blender and SketchUp, since the K-frame animation in Blender comes very close to the animator.
I render my MSPhysics animations with IndigoRT because AntonS programmed an export for it. Meanwhile, the Denoise function works very well, so that the rendering times for smooth single images are acceptably short (in daylight ...).@ pilou: that looks fantastic! I can't get enough of it. This is the ultimate professional way. Unfortunately difficult to combine with the SketchUp universe. SketchUp -> Cascadeur yes, back no ...
-
@faust07 - thanks for the tip, I'll investigate. As you can see, I'm pretty novice at SketchUp.
You write, "To let animated characters from other programs act in SketchUp, I consider the current state of the SketchUp functions to be impossible."
It is possible to get complex animated characters in to SketchUp scenes, as demonstrated in my hippy man jogging video (link above). The SketchUp scene and animated character can be brought together in a video editor which can import 3D models, like Hitfilm for example.
That said, Dave is hoping this thread will reveal ways to animate characters WITHIN SketchUp, a more challenging agenda.
-
Sorry guys, I had hoped to have something by now but it has been almost 3 years since I did anything with Animator so I have had to watch some videos to try to get back to some things. Might be a few more days. What I wanted to do was create something like Nukeman did in his video but with the entire thing done in SketchUp.
-
Hang in there Dave, I'm sure you'll build upon what you've started. Look forward to learning from what you accomplish. Thanks for starting this thread. After a slow start I'm starting to get in to it.
On my end, I just successfully imported a SketchUp model in to Cheetah3d. And I see that character animation is definitely doable in Cheetah. So for now at least, it looks like SketchUp models and animated characters can be combined within Cheetah3D. This is better than using Hitfilm, as with Hitfilm while I could import animated characters, I couldn't really animate them from scratch.
I have a long way to go yet before I'll really know what I'm doing, but Cheetah3D does look a lot easier than Blender, so I'm happy about that.
Cheetah3D is Mac only, but I'm sure there must be Windows equivalents.
-
@faust07 - thanks a bunch for the tip on pivot points and transparent styles. I haven't been able to get one of the artist's characters in to Mixamo yet, but I can now repose them, which is big leap from where I was before your tip.
The process looks like it's going to work in Mixamo, but then at the very end of process the character vanishes. Will research further.
-
Just a quick update to show that I am headed in the right direction with a LONG way to go. Kind of sad how much I have forgotten and some things have changed/improved since I did this before.
I promise I will get there. -
Very good approach and perhaps for certain animations it is enough for people to slightly move their arms, head, tilt or turn their upper body.
This creates the impression that the scene has not been populated with rigid figures. Technical simulations with people can be a bit more complex, for example when tools are to be guided.
In architecture visualizations I have found that people who are too realistic and moving are extremely distracting from the actual "content".
In urban development simulations, such as the representation of busy street spaces or traffic flows, moving people and vehicles are in turn very useful for the goal.
Today I could remember such a simulation with Animator. Here is the link:
https://sketchucation.com/forums/viewtopic.php?f=401&t=64948&start=30#p599837
Perhaps the author is still active and can give good advice or post animated models. -

There are a couple objectives (IMO) for this thread:
- Prove that characters can be animated in SketchUp (original goal was with Animator thus the name of the thread)
- Produce something like the 2 examples in the thread you (faust07) pointed to but with the 3D characters animated
- Reproduce something like Nukeman's animation but completely in Animator and not having to use multiple tools to combine things together.
I have watched some more videos today to refresh my knowledge of Animator and believe I have not recouped the things I need to produce some similar to Nukeman's animation. Might be a couple of days before I can get it all done (have some personal things to complete).
Want to say that I hope the thread participants will continue to participate.

Another quick update to let you guys know that I am making some progress after some silly mistakes and having to go back and learn some things again. The gif file below is to show that I can animate a character and have it follow a path. Now I have a bigger plan to make it look more like the thing that started this whole exercise.
Before you write it off, let me acknowledge that the animation of the man is certainly not as good as I would like it but my primary objective here is to show that with Animator (and to faust07's suggestion MSPhysics) you can produce something like Nukeman's original animation. Just be patient and keep an open mind (at least for now). The biggest problem I see so far is to have the ability to bring in rigged characters into SketchUp that can be maneuvered to achieve the type of animation we are shooting for.
-
OK everyone, I have finally created a video with Animator of an animated man walking through a scene. It certainly could be a lot better, some of you could put me to shame with it but my goal was to show that it could be done all within SketchUp with the Animator plugin.
Here is the video........
https://youtu.be/DTz-ItV7x0AYes, there are things that could be a lot better:
-
The character is not animated as well as it could be.
-
After some discussions with Fredo6 (Animator author) he plans on implementing kinemetrics in future release which will give you more control on the character being animated
-
I tried using pieces (say like the upper and lower arms, the same with the legs, and the foot could not be broken into parts to allowing bending of the foot) but the parts of the model were not constructed in a manner that gave me full control. Yes, it is a rigged model but not quite well enough.
-
Given what I did accomplish, as I was watching the video, I noticed that I made an error in the coordination of the movement of the arms and legs. The arms should be moving in sync with the opposite leg. As an example, as the right leg moves forward, the left arm should move forward instead of backward. Silly mistake
-
The character does follow a path but I think it could have been done better (more practice needed)
-
The overall background could be better.
-
I did use different camera types but again, it could be better. My objective with the cameras
was to: -
Stationary cameras were used to create some transition from one camera position to another
-
In 3 different places, I used a camera to follow an object (the man). This was the first time I had done that so it could be improved.
OK - it is out there now so again, my objective was to show that it could all be done inside SketchUp. I did try to use Twilight Render to render the whole thing but it was going to take about 21 hours for the render so I just went with the basic stuff.
Of course your comments are welcome.......

For me this is a very understandable learning and knowledge process. Character animation is highly complex and everyone immediately recognizes deviations from the realistic movement of living beings. In the case of simplifications (due to a lack of technical possibilities or a lack of time), the environment should also be kept abstract to the same extent, otherwise it just looks funny. My attempts also fail because the claim and the actual presentation differ widely and self-doubt often prevents a presentation. It is refreshing to see your consistent pursuit of the topic and your progress. Go on! I would like to give specific help, but I don't have the time to deal intensively with Animator. In any case, Animator has the potential for it.
-
I was going to try to correct some of my character problems but found that I could no find a satisfactory pivot point for the lower leg segment. I tried to find another character in the 3D warehouse but did succeed.
I like the guy you have swinging the lantern. In your wireframe view, it looks like he would be a good candidate.
I also want to create a scene that does not have all flat surfaces so/we could look at the ability for the character to navigate a hill/valley environment. I wish I had the skill set of you and Nukeman.
-
Hey Dave, congrats, I see you are making steady progress towards your goal.
Honestly, I'm guessing animating people in SketchUp will always be pretty limited, but it's interesting to see how far you can take it. And, I get the appeal of staying within one software, because moving characters from one environment to another is typically a pain in the butt.
Should you wish to expand your focus at some point I'd be happy to discuss Hitfilm (free) and CrazyTalk (cheap), both of which are available for Windows and Mac. But I'll hold off for now so as to not further interrupt your current project.
Keep it coming, watching with interest here.

Here is the model you want. I've provided the no longer functional MSP joints with axes that you can use as pivot points. It includes essential pivot points for walking and running. In MSPhysics, I use the pistons to lift the legs using a kind of hip movement. This is important for overcoming uneven terrain.
The joints in the neck and hips are important for more natural upper body and shoulder movement or for head and stooping movements.
-
Thanks for sharing faust07 but I have a couple of DUMB questions.
- I assume the pivot points I see are from MSPyhsics. How do I remove them? (I do not have that plugin)
- How do I get the character to show up with the normal clothing and etc.?
-
To 1.) Yes, they are from MSPhysics. I left the joints in the model to make it easier to find the right pivot points for the body parts. The joints can simply be deleted or the layer can be switched off.
To 2.) What do you mean by normal clothing? Maybe turn off SketchUp transparency?
