Bump and bump map node should be linked where? Thanks.bm.jpg

I'm a newbie ... but from my experience with cycles in Poser ... in this configuration I would put in in the displacement node. But a Blender guru would have to verify that.

OK I do not see the image your using to be your Bump texture and on thing I know you must make sure is what ever the image is when you connect it to your bump node the image has to be set to non color data. You have Bump node going into a normal node but no image texture connect to that bump node

I'm relatively new to Blender myself. But here is how I set it up using Cycles and the Principled BSDF shader. The bump image isn't linked directly to the Principled shader, so you should be able to use it with other shaders. Basically I have the bump image texture, with it set to Non-Color Data, going into the Math Node, set to "Multiply" to adjust the amount, and then into the Displacement link of the Material Output Node.

(Here is more information regarding the Principle BSDF shader. I like it because it is a bit similar to using the Iray Uber shader in Daz Studio. https://docs.blender.org/manual/en/dev/render/cycles/nodes/types/shaders/principled.html )

Hi Guys erock3d One thing you could try with that is to plug the colour output of your bump/height map into the height input of a bump node then plug that into the normal of the principled BSDF this will give a slightly different effect and a little more control over it. You can still use it as a displacement input will vary the results even more.
