Animated textures

Hi;

I'm trying to render something onto which I'd like to map an animated texture.

Inside an Octane Network, I have a TextureImageRGB node. Into the Filename parameter, I've entered a path like this:

$HIP/animatedImage/ahimatedImage.$F.jpg

I notice that Octane seems to render the expected image when I do an IPR render, but does NOT render an animated texture when I do a batch render. Can someone help me understand how to do this properly?

Further debugging this problem, I realize I've misdiagnosed my problem. To add clarity:

I have a plane (a "grid" in Houdini parlance) onto which I'm projecting camera UVs. I'm mapping a live-action plate onto this geometry (so, my image sequence is animated, as are the UVs on the grid).

What I find is that the animated plate texture is indeed updating, but the camera UV's are NOT. This leads to some odd artifacts that were tricky to visually diagnose.

I find that if I set the RenderingMode parameter on my Octane ROP to "Full Scene Reload" rather than "Update...", the camera UVs seem to update per-frame properly.

Would anyone be able to direct me to some documentation that explains this in detail, so that I may understand it better?

You have some details about this feature in the docs:
https://docs.otoy.com/manuals/products/ ... -rop/main/

Update the mesh UVs could be indeed one of the features not supported in update node, so as have found a full scene reload for each frame is needed.

Thanks,
