I'm trying to add a USB port and a volume dial to my model. I can't get my head around how to do it though. Can anyone advise me on workflow here? I don't model and bake here, right?
Yes, you could certainly add them as floaters, or what I do now instead of floaters is just paint them directly into the normal map in Substance Painter. Or you could model some of the basic detail into the low poly if you can spare the extra verts, and bake the edges of the cutouts/dial. Or you could boolean model it and…
If you're just straight sub-d modeling the highpoly it is quite painless as it's all square/angular shapes.(cylindrical cutout isn't a problem either as the detail is still intersecting square/angular forms) Personally I'd model it planar by edge-extrusion, lay out my basic forms and edgeloops with minimal geo, add control…
