Editing bump size texture

[dldieterich2]

I’m trying to recreate velvet and leather using some great info on an older thread.

However, I seem to be missing something crucial in this use and others. When I try to use a material (other than the albedo) for the bump (here a stucco), I can’t seem to control the size of that bump material in its appearance on screen. I’ve tried resizing the material in Photoshop (here, for example, the texture is only 1" X 1") but the bump still is on a way different scale in the rendering. I’m attaching a few screen shots. I would so appreciate if someone could illuminate me.

Thanks in advance!

Did you try the settings under “Explicit texture transformation”?

@dldieterich2 , this might be what you’re looking for, what @Epix_3D has shared?

This ‘Explicit texture transformation’ has been an absolute revelation for me. I’m currently doing a building with Zinc cladding and the ability to have a fine grained drawn metal texture AND a massivly overscaled subtle bump to give the ‘not perfectly flat’ feel is producing amazing (for me) results.

Now I know this feature exists I’m going to be using all over the place … Thanks Epix
