I am trying to combine the result of two black and white node based textures to use it as a bump map (by pluging the black and white texture on the height input of the bump map node) but only result having this weird broken result:
Here is my first bump map:
Here is the second bump map
Here the black and white texture when mixing the two separate textures:
When connecting this black and white map to a bump map node I get this:
but when connecting the bump node to the principal BSDF it is all broken:
I try different ways to connects the nodes as seen in this topic (How to combine Bump Maps?)
but get the same broken result.
Any idea why this happens and how to fix it ?
I have made a small scale test with two texture and it worked fine:
so something in the node system must be messing with the end result:
Here is the blend file:
