How can I import some wz3 stuff to wz4 like it was with Debris?
Interesting, can I get some animated monsters from Kkrieger?

Hi
If you look here https://github.com/farbrausch/fr_public ... 33_ops.ops
you gonna see operators that might interest you. For some reason they are omitted at building stage...

Do you know how to export mesh from XSI to WZ with material IDs and UV proections?

I didn't check if UVs were also exported (i guess they actually are), but for material ids: create your clusters in XSI, export *.xsi, import it to wz4, and use 'cluster' input option in the Select operator. Cluster number param cycles through the clusters you set in XSI.

I know about clusters, but can't acheive same as in XSI UV proections with it.. ((((

I see. Maybe I'll check that later...

When in trouble exporting UVs people advise to use Transform -> Freeze All Transforms before exporting the *.xsi.
Have you tried that?

It should be possible to load wz3minmesh with import operator (mesh) (look at supported extension in open dialog box).
But don't know how to export in wz3...
