Sculpting framerates

Support Basics & Interface
1

Hey, guys. I’m doing sculpting on a full body model for the first time and it’s an anthropomorphic character, so meticulous sculpting is required int his instance. The problem is, when I raise levels in Multires up to 5, it’s really tough to do detailed sculpting without the cursor lagging out on me. Are my specs fine?

If they are, what are some tips I could use to make sculpting a little less of a pain? Thanks!

Never start from just the basic cube. Subdivide it a whole load of times before using mustires modifier and you’ll get better perfomance at the higher poly counts

3

Do you mean to subdivide the cube or the current model I have? I didn’t intend to go very far with this since I know there’s some important stuff I’ll miss, but if I have to start over I will.

4

You see, the thing is I basically start with the simple mesh and work my way up until I have a discernible figure, like the anthro, and then I hope to sculpt that. What the video seems to suggest is that I want to sculpt from the ground up.

5

Enabling VBO and disabling double sided were the key things for me. Sculpting was completely unusable before fixing those, and it improved overall performance too. Apparently this is most significant on nvidia cards.
File -> user preferences -> system -> check VBO
Object data tab in properties panel (upside down triangle, not the cube) -> normals rollout -> uncheck double sided

6

Thanks for the tips. I disabled those, but found that changing the “spacing” also helped. Mine was all the way at 1% and performance while sculpting got better when I brought it back up to default 10%. I guess I’ll just have to stick with that.
