Problem with Converted Materials in UE Tweet

[colsa16]

Hi!
I tried to import a geometry with one material from a orbx generated in c4d and I set the option Previz Materials in the import settings of the octane plugin in unreal
This is the material nodes in c4d



And this is the result of the Converted_Material in unreal





If i remove all the new nodes created on the left, the material works so I don't know if this is normal or i have done something wrong in the import process.
I'm using the unreal 4.24.3 with the last version of the octane plugin and the 2019.1.5 of the C4D octane plugin.

Looks like a uv coordinate bug. Could you share your orbx file with me?

Any idea?

Yes, I found the issue. The fix will be part of the next build.

It seems that C4D creates empty uv transform nodes, which the converter didnt expect, resulting in random UVs.
If you want to have this working before the new build you can fill the UV transforms with the default 2D transform node before importing into unreal.

Example of empty uv transform:

Thanks Chris!

I have one more question.
If i put a displacement node into the material in octane, when i try to convert it in unreal, the converted material doesnt have this node and the displacement option is empty. There are any plans to fix this?
