So im trying to learn how to mix materials. Im mixing to seperate BSDF materials with a mix shader, and I am setting the mix with a image texture that I use as a mask. (in this case… the shape of a word).
The different BSDF shaders both have their own roughness map to give the material its depth.
But I would also like to add some height/bump to the edges of the mask, so that the shape of the word gets some height (so it looks like an extrude)…
Im not sure how to do this. Normally, i would connect a bump node to the mask image texture, and then to the normal input of the bsdf shader. But thats already occupied to set the bump of the bsdf material.
So how can I solve this?
Additionally, a quick question about the displacement node in this node tree… im not sure where to connect it to…
And secondly, in Nodewrangler… when you press ctrl shift click on a node, you get a preview. But how can you cancel this preview?
