Ok, in an ongoing effort to disprove “there are no stupid questions”, I am going to try…
I have a simple rod shape made of a carbon fiber weave (think fishing rod or pool cue shaft, or javelin). I’ve done quite well in blending a number of shaders (anisotropic and principled) together so that the light hits the material and reflects the various directions of the fibers from different angles. I have mixed the shader nodes together, applied some nice noise to create irregularities in refraction so it looks “used” and has finger smudges etc…
BUT, I would now like to simulate an laser-engraved logo on a specific part of the shaft. It should just “roughen” or depress that part of the material with the company logo or other text.
Ive searched tutorials, youtube, these forums etc. and feel like this is such a common thing, I must be going full NOOB.
Do I need a second UV map on the same object (rod)?
Should I try to use an alpha map on all the other shaders to exclude it there?
Its driving me nuts! Tanks in advance!
