Sources of more compositions, objects, etc

[talented]

I've been to the usual sources to secure objects, compositions, etc with those sources without activity for years.

Are there any current sources, active sources of material for 3D production? Even sources that require payment?

Also, are there compatible 3D files are developed within other 3D software - composition and object files?

Thanks.

Without knowing your "usual sources", have you had a look in the Free Stuff and Commercial Software sections of this forum?
