Title: alembic object mapping
Post by: britbunkley on 2022-02-09, 06:32:43
I purchased a model from CGtrader. It was in Blender which I don’t use except for conversions. I use 3dS Max and Cornoa. It was a model of a subject that I have been looking for for some time now, a Pere David’s deer – and a great one at that. So I took a punt and bought it.

The FBX files from Blender will not come into Max with animations, but the alembic files will. However, they come in without the materials. I spent a while putting the materials on but there is one problem that one material that appears to only cover part of its body. There are 2 “body” file images -one covers most of the body, the other the head and muzzle. But both won’t work at the same time. Would some wort of layering work? But using the “layer material the image map doesn’t come through.

if I could convert the alembic file to a mesh and keep the animation that might make it easier, but so far, I have not figured out how to do it. The animation disappears with the mesh conversion any way that I try (exporting as an FBX or just collapsing layers).

Any ideas?

I don't work with alembic files, because 3ds max version that i'm using, has critical bugs with that format, so i don't have much practice, but i would try following steps to pinpoint the issue - add unwrapp UVW modifier to your alembic mes and check UVs, see if there's anything unusual going on. If UVs are good, add edit poly modifier and see if model sports several material IDs. Alembic is good format if you don't need to edit animation, but Autodesk's implementation is leaving to want more, as it is usual in such cases.
