Render texture with image sequence in GPU mode not right working

V-Ray V-Ray for Rhino Issues

Hi,

I have a scene where I used an image sequence as texture and I run in following issues:

* diffuse texture works in CPU mode only, but the texture is ignored in GPU mode
* texture works at a rectangular light like a slide projector, but the intensity can’t be changed, it looks like always 1
* it helps to increase the diffuse slider of the rect light to get more intensity

I tried a spot light and here the sequence doesn’t work in GPU mode, if sequence is enabled than the texture is ignored.

Hello again @Micha ,

Thank you for creating a separate thread for the issue.

* diffuse texture works in CPU mode only, but the texture is ignored in GPU mode

As I have shared in this post we have logged the issue as VRW-4093, also you are right that only Rectangular lights work with image sequence in the Bitmap.

* texture works at a rectangular light like a slide projector, but the intensity can’t be changed, it looks like always 1

This is a known issue logged as VGPU-5095, apart from the workaround that you have suggested with Diffuse slider, the other workaround is to change Directionality to 0.99 instead of 1 (also posted here).​
