VRay 4.2 - Problem with API (for Animator)

fredo6 · 28 Jun 2020, 20:13

Animator integrates VRay in the list of supported rendering software for generating the video of an animation.

Since at least VRay Next 4.2, the interfacing with the VRay API has got an issue: it does not takes into account the object movements (but it does for camera).

This used to work fine with v3.4.

Is there in this forum anyone familiar with the VRay API?

Animator basically computes the position of objects and of the camera, and then calls VRay for rendering each frame individually. The reset of the environment between each frame is done with VRay::clear_renderer, which apparently does not force any longer VRay to pick the new position of objects.

Hello Fredo, I'm using Vray Next 4.20 on Sketchup 2019 with Animator with Animator v3.6a on a LibFredo6 v12.5a.
I have an issue rendering an animation with your animator plugins (which I believe are the latest versions at the moment) the rendering always stops at 20-30%...ALWAYS. Its been really confusing because it renders a normal box well with Vray but when I want to render my project which is like 6mb in size or less it freezes at that 20% range. Please what could be the issue?
PS I had the same problem on Vray 4.1 also. Looking forward to your reply. Cheers

Rendering of long animation has always been a problem with VRay, because it requires a lot of resources.

What is average time to generate a frame when rendered by VRay?
