Ports/Dials On Devices -- How To Add To Model Without Modeling

allengingrich

Let's say I want to add a stereo jack or a USB port to a smartphone I'm modeling. I don't want it to be modeled -- it's a lower poly model -- but I want the normals. Do I have to model it out, or is there a different way using alphas/bitmaps? How would I accomplish this (using Maya/Substance)? Thanks!

You answered already. You can use a heightmap with substance.

Right, I just done understand how I generate the heightmap for something like this in the first place. Can you give me a clue to a resource? Thanks.

You can Paint normal/bump/height information directly to the model in Substance Painter. Just add a layer, turn off all channels except height, use alphas to add positive/negative detail. This data will be added to your original NM when your export maps.
