Insert mesh brush: PRESERVE UVs?

ZBrush Usage Questions
#1

Hi,

Is there an option to preserve uvs when creating a new Insert Mesh brush? It would save me a huge amount of time.

Thanks.

Ouch, so the UVs can’t be kept… This is a big drawback.

Thanks for pointing me to the answer.

The reason is that UVs are totally reliant on topology. If you change the topology, as you do when inserting a mesh, then the UVs are no longer relevant. Although in theory you could retain UVs for the inserted object, so that they overlap existing UVs, as the number of inserted meshes increased this would quickly create memory problems.

Well, for the the low amount of polygons my brush is generating, I’m sure it would be possible to preserve UVs without any memory problems. It can’t be that intensive. I can take a UVed teapot in 3Dsmax and duplicated it hundreds of times without any problem, zbrush would be able to handle it if there was the option, I’m sure of it.

You can certainly ‘paint’ tons of copies of your object, positioning and rotating them along the way. This is just for an image?

I’m making braids so I need it to be continuous. I need the uvs to set the flow of the anisotropy for the reflections so it looks like hair. I ended up uving after I exported from zbrush. It was a long process but it’s done.

Possibly a tri-parts insert brush would work. There’s some for rope and frills, and bramble bushes. Not sure if someone made braids.

That’s what I’m using.
