CUDA crash when enabling rounded edges + texture displacement

1. Load orbx and click the render target to start rendering
2. Select the mat1 nodegraph
3. Set rounded edges mode = accurate

Cuda crash:

Thank you for the report, we will look into this and fix it in the next release.

I have a setup that uses vertex displacment and a texture for the color input.
Why is it that when I change the UV transform scale of the color texture, that octane has to calculate for a minute before I see my result. When I disable the displacement, the changes are instant.

Fixed for next release.

Universal material + emission bug

Something seems to be broken with emission on the universal material. Its OK in 2019.2 XB1, so I assume you already know about it, but I'm posting here just in case

1. Load the attached orbx and select render target
NOTE: The cube should be emissive, but it isnt

2. Select "box" nodegraph and set specular color to 0 (or coating to 1, or transmission to 1)
NOTE: Emission starts working again

Thank you for the report, we will look into this and fix it in the next release.

This happens with simple scene with VDB objects too.

Thank you. This will also be fixed in the next release.

Universal material / transmission bug

The first 3 transmission models dont seem to change anything unless you have an albedo texture plugged in.

Something isnt right here, because when you add a black (0) albedo texture, it changes the appearance. Black and disconnected should look the same.

1. Load the scene and render the universal material
2. Switch transmission model between octane / beckmann / ggx
NOTE: Nothing changes

3. Disconnect the albedo texture and repeat step 2
NOTE: now the material is changing

UPDATE: If you disconnect the albedo again, adding coating or specular color prevents the transmission from working too

Denoiser bug:

The denoised version of this material is brighter.

This is expected, because if albedo (diffuse) is not present, then the transmission layer and the specular layer essentially becomes a specular material on its own, and so it uses the same model as the one specified by "Reflection model".

It's only if there is diffuse layer separating the specular reflective layer on top of it and the specular transmission layer below it that we allow changing the 3 specular transmission models.

I have fixed this and this will be in the next version.
