Bump / Normal map not seen in final render

[Noah_]

I wanted to do a test with the anvil of the Blenderguru tutorial but in luxcore and I have this problem



Anyone know why this may be happening?

You should post a test scene and some information about the version you are using

The file is heavy

Blender 2.82/Luxcore2.3beta2

I'm not going to download this file for 3 hours.
Can you strip it down so it is smaller, but still shows the problem?

Three hours? BYOB I live in a third world country with 10 megabytes I download it in 20 minutes

I will try, if the problem remains

I guess the hoster throttles the download rate?

You can replicate the problem with a plane

This is a known limitation/difference between CPU and OpenCL rendering: you need to connect the the bump mapping to the root Mix node, not to the 2 Disney sub-nodes. Just mix the bump map textures and connect the result to the bump socket of the root node, you will have the same result between CPU and OpenCL.

Wow thanks Dade but ...

Do you have an example image of this?

Edit:
I understood, connect the relief map in the input bump of the material mix.

Works. Thank you
