Sculpting brush quality issues

pancreasboy · November 25, 2022, 5:22am

Hey there guys,

I’m trying to add details to a model that will be 3D printed and I’m using a 4k alpha brush but it’s too pixelated unless I use 10’s of millions of polygons. Is that right?

ie with the back of Suzanne’s head as a test, I’ve used a Multires modifier at Sculpt level 6 (2 million polygons), then 7 (8 million polygons), then 8 (32 million polygons).

Do I really need that many polygons to get the detail quality I’m after or am I missing something?

Thanks in advance.

I think that for this kind of detail, you should just bake it to a lower res mesh as a bumb/displacement

Yeah but this is for a 3D print, so I need the geometry information

You could use dyntopo to localize high detail areas

yeah I did that too and it was slowing down my machine as well (ie I have 64Gb RAM)

You don’t need both multires and dyntopo, you can use one or the other just fine. Both will be very slow.

Thanks for all your replies guys, I went with Dynotopo and it came out alright on my 4k resin printer, I know on a 6k or an 8k it would be even better and I’m trying to future proof it too.

Thanks again.
