Hi everyone. Quick background info first. I’m making meshes for import into Second Life. Multires is a very important tool for this application, as it’s used to show how the model will deal with lower levels of detail when a user zooms out.
For this reason, it’s generally common practice to work with a mesh at 1/4 of it’s final resolution, so that when users zoom out, the key vertices defining the shape remain in place, and things don’t distort.
I need a little help with multires in general, though. It seems to be lacking for what I want to do. The scripts I use for generating SL compatible meshes, start off with the mesh at 1/4 resolution, and 3 multires levels. Allowing multires to be used to preview it at various detail levels. I’m trying to work at the lowest detail level, but the mesh keeps shifting around. Generally, if I position vertices at the lowest level, I’d expect the extra ones to appear in neat inbetween places when I increase the detail level, but this doesn’t seem to happen. I can sort of work around this by deleting and re-adding the multires, but this solution isn’t particularly great.
Is there any way to lock the lowest level vertices in place when going up multires levels, so that they don’t shift around? Or does anyone have some general advice/tips on using the multires function in general ?
