Different result between CPU and GPU

[Zakkorn]

I am new to RT and I have a question.
Probably it will be obvious to the most of you but as I said I am new to RT and I don't know how it "behaves".

I have attached 2 images.
One is rendered through RT with CPU and the other with the CUDA engine.

The CPU result is similar to the Vray (not RT) result (BF+LC etc.)
The GPU though is like its lost its specular somehow.

Also in another scene that I tested the GPU, the whole image looked colored tinted and again no specular.


Is it normal?

And how can I overcome this?

Thank you in advance

I found what was causing the issue.
I had a Falloff map to the RGlossiness channel.

I didn't expect that the falloff map will be incompatible with RT

It should be. Can you share the scene so we can take a look ?
Thanks.

Sure!

I have sent it to support

I found out that that the Mixed Curve in Falloff causes the issue.
If I have a Falloff with the default Mixed curve, it works.

Yes, it is now logged to our bug tracking system. Thank you very much.
