Jagged Lines in Textures - Substance Painter/Tips for Highpoly -> Lowpoly Workflow

Alander787

Hi!

I come here to ask two questions.

1st is, is this problem with jagged lines in textures caused by not having 90 degree UV islands?


And also, I would like to know some tips on the workflow with highpoly to lowpoly.
I would like to know how would you approach the texturing process where you would be able to use the texture for both versions.
I need lowpoly for real-time stuff, but I also need the highpoly for close-ups etc.

Also third question, how can I speed up the retopology process? Is topogun usable for hardsurface?

Eric Chadwick

Yes to the first question.

There others depend on the asset and usage. More info needed. LODs probably would solve your high/low issue.

My collegue needs a highpoly version of a model I've already done in low poly, for a promo, where the camera takes a close-ups on the model, like in product adverts.

New model then, and new textures. Up-rezzing a lowpoly model rarely does any good.
