I think it may be part of the "Fixed incorrect denoiser output in scenes with SSS materials.", but I'm still seeing a color difference in the denoised output.

It's not as drastic now, but the denoised output is a bit more blue.

Sorry, I'll look into it.

Thanks,

I am having issues with the specular component of the shaders.
The specular part of the material randomly disappears when moving the camera.

Attached are 2 images, one looks normal the other I get when I move the camera a little bit to the side.

I am using RTX 3090 and Nvidia driver 466.47

Im on a 3090 + 471.11 and tried to set up a similar example but cant reproduce the problem. Can you share an orbx?

Can you answer the following questions:
1. Can you provide a scene?
2. Can you reproduce this problem when you switch RTX off?
3. Are the normals on the box flipped (pointing inside)?

Dear Wallace,

With RTX off it behaves normally.
I will send you an example scene right away by private message.

Kind regards

Thanks!

I can confirm that this is a bug I have fixed a few days ago. The fix will be in the next release.

I just want to tell you that the volume texture is really awesome!



I have only one problem, if the vdb is empty the texture turns white. It would be much better if it would be black in this case

BUG: RTX on using 3090 renders incorrect glass in this example

I'm noticing some of my old scenes look broken with RTX on again on a 3090. Here is a simplified scene. The glass is no longer transparent with RTX on. RTX off is ok.

I'm using 471.11 game ready driver

BUG: Vanishing specular reflections with RTX on using 3090

Im pretty sure this is the same bug manalokos was running into, but just in case it's not, here is a sample scene

Load the scene and scrub from frame 1 to 2 and you will see the specular highlights vanish.

I tested with a 3090 + RTX off, and a 1080ti + RTX on and it works correctly.
