[Plugin] Smoothstep Animation

thomthom

I've wanted to set up an object-animation extension for a while. (Alas never had time, and probably never will ) One where you have a timeline window and you control the transformation of objects. There appear to be interest among render engines to support this if someone created it.
Seeing how popular Skatter has become - filling in the need for proxies, I think an animation extension would also be of high demand. Even if it only animates instance transformations.

Thomthom,

You're right. This is a rather significant undertaking!

I working on animation plugin lately, but still far from completion. As you described, It uses a visual timeline and is purely parametric (i.e. not based on the Sketchup Scene animation mechanism), so that you can freely change the object transformations at any point.

Below is a short video capture. The UI has changed a little bit since then, but this gives an idea.

WOW! I especially like the exploded homer

OK - now "the cat is out of the bag"

I have wanted to hint about this before.

!! whoa! Yes! Like that! I like that!

I also like how you did the timeline vertical to save viewport space. I'll be closely watching this!

(Btw, from a technical point of view, do you use .move! when animating?)

Hi Whaat, good to hear from you!

Absolutely there is demand for your plugin; I use it quite a lot. The other flythrough plugins around require you to create spline camera paths and generate multiple tween scenes that force you to save multiple copies of your model... this becomes a major nuisance when there are design changes. And don't get me started about the face-me component artifacts when using SU's base animation exporter...

There are 3 issues with the Smoothstep plugin that are a bit of a problem for me at the moment:

1 - When generating frames, at certain points the time to generate a single frame can suddenly blow out dramatically. I have attached a sample file. If you just generate the animation using the standard settings, at frame 33, you'll notice that SU seems to freeze. When generating this animation in Full HD, that particular frame took my computer 2 hours and 52 mins. It is not obvious what causes this problem but possibly something to do with face-me components coming into view. Happens on both my PC and Mac.

2 - There is a small jump when the SU changes over to the next scene. Very small but still noticeable.

3 - If you exclude some scenes from the animation by unchecking the "include in animation" checkbox, those scenes are excluded but a whole stack of still frames are added to the end of the animation. This just means that you are rendering stuff unnecessarily and you often have to force close SU to stop it which isn't ideal.

I love your work and as I said, I'm willing to donate to see that some of these small bugs are fixed.

There is something weird in the style of the model that makes Sketchup freeze when views are changed by program.

This is true for the native animation, whether Play or Export Video. This even happens when you change scenes manually.

I notice the same behavior when building a fly-through animation based on your scenes with Animator. Sketchup seems to block and freeze at certain transitions, which makes the generation quite long (I cannot attach it here as it is too big, but I can post it on YouTube if you are OK).

Anyway, the model is useful to me for Animator, as it shows that Animation should be edited with simple styles, using complex styles only for generation of videos.

EDIT: I investigated deeper this problem of freeze:

for some frames, and inexplicably, write_image can take more than 2 minutes
this seems to be related to the watermark
This has nothing to do with the face-me components
