Several Render Orders? [TUTORIAL]

thomthom

You could set up an animation where you render off one image per scene.

You could set up an animation where you render off one image per scene.

i have tried that but dint work for me i made the scene transition to 0 also scene delay and still it rendered it as a video

fbo_bern

hmm...
Can somebody write a simple, cool Tutorial for it?

fbo_bern, i'm assuming you're refering to a batch render process. This is what I have to offer on the subject...

Step 1

Window > model info > animation.

1.1. Enable scene transitions
1.2. Set scene transition to 1 second
1.3. Set scene delay to 0 seconds

Step 2

VRay for sketchup render options > Output

2.1 Pick preset or specify output size
2.2 Under the Render Output sub option, enable 'save file' and specify output directory and file type. (VRay can not render out a move file but rather a series of stills which can be combined into an animation in video software if required)
2.3 Under the Animation sub option tick the 'on' box and choose a 'Custom' frame rate specifying the FPS value as 1. This will effectively render out 1 frame per second which when combined with the sketchup settings from Step 1 above will produce 1 frame (still image) per sketchup scene

Hey presto! Batch rendering achieved.

The VRay specific switches could be saved as a visopt file for future quick call up...

Please note: This process has its limits as I have found out through trial and error that any layer visibility or object visibility switches set to occur between sketchup scenes are not effected when VRay works through the scene list whilst changes in sun settings are. This is important to remember if you plan to push a button and automate things overnight as you may come back next morning and be dissappointed.

Further still it seems that the active sketchup scene selected when starting the vray batch render process will set the precedent for the subsequent scenes rendered in terms of layer and object visibility. What this means is that if you start on a scene where an object/layer is hidden, in all subsequent scenes this object/layer will be hidden too and visca versa, despite the sketchup scene settings and switches being correct.

I suspect this is a VRay issue and hopefully is something that will be resolved in the pending new release!

If you don't have any tricky layer/object visibility changes between scenes then this works a treat!

Hope this helps.

hey david

thank you! the guidance functions perfectly. wonderful!

Has anyone tried the animation/batch render process using the new sketchup. I may be missing a step, but it doesn't seem to be working. I'm only getting one image out, the image keeps overwriting itself, so it renders several shots but then saves over top of the same file.

Has anyone had this problem yet?

UPDATE: There is a tick box for "Include Frame Number" that I needed to click in order to render out to multiple files. That seems to have taken care of the problem.

Hey tomthom, how can I render an animation ie. scene by scene transition in Vray for SketchUp?

wahoowetzel

I did it by setting up an animation in sketchup and then going in to the output rollout for vray and turning on animation and your frame rate as well as creating a folder to save out all of the images (that you then combine in After Effects or some movie editing program). I will say that it took me an excessive amount of time to get just a 4 second video. I had decent settings for a 2000x1000 video and at 30fps (15 fps might be good enough though) and 5+ minutes per rendering it took a looong time to come up with 4 seconds of video.

I'm curious about saving IR and other light info to be used in each frame as a time saving measure, has anyone played around with this as a more efficient way to make "vray videos".

Since we just got a new VfSU version, and since have changed quite a bit. Please state your VfSU version when asking questions. The answer will depend on this factor.

trying out beta 1.6 and still no layer/object viability control? 3 years later?

?

What you mean?

Krisidious

Oh I was searching for why my layers are not changing in vray animation and found this thread. here's where I'm at.

dkendig

we currently don't process changes on a per scene basis, for anything other than the camera.

Krisidious

So fly through would be a more proper description of what Vray offers than animation is. Just wish i would have known that 5 days ago.

dkendig

I suppose that is a more accurate description of how our animation support has traditionally been done. We aren't done adding and changing things for this release yet, so don't lose hope. The reason we currently don't support per scene changes, other than the camera, is that this requires re-parsing the scene (which in some cases can be very time consuming). In 1.49.01, the time it took to parse a scene was significantly longer in many cases, than it is in the 1.6 beta, so re-parsing for each scene was out of the question in that version. Now it's something we can consider doing. No promises, other than the fact that we will try.

Krisidious

I tried Twilight and it took 49 minutes to render one image out of 289 frames... and the quality was not even close. I stopped it. layer visibility or object visibility, either one. and if it takes longer, well it takes longer. I can live with longer. I'm getting pretty descent render times, like maybe 1-3 minutes for a 1920x1080 and I'm on a i5 2500k overclocked to 5ghz.

Right now the only work around I can see is using one of the animation plugins like camera recorder or advanced camera tools to create 1 scene for every view point, (this negates scene transitions) then go through and render each scene manually.

dkendig

this is something that users have requested for a while, but there are some other big items and bugs that we are trying to deal with before venturing off on to this quest. If, for whatever reason, it doesn't make it in to this version, it will be in an update soon.

Krisidious

ThomThom can you make a plugin to do that? to make a scene for each transition change to it and then hit render for each one in succession?

eddiemoney

Did anyone every make a plugin for or find a solution to this? I am experiencing this now and it's extremely time consuming to sit and watch each scene render so I can manually change to the next scene, where certain objects are hidden / unhidden.

If I just hit render, whatever is hidden or unhidden in the first scene is how all scenes come out. Only thing close to a solution I've found is to manually change each scene in between renders... which means I cannot sleep tonight lol.

Thanks!

Batch render in 2.0 solves this now. It's pretty straightforward.
