Not author but if you're sharing these assets, distributing them in the gltf (json/ascii, not binary) format is really helpful, as it seems to quite easily be imported into tools like blender and threejs.
Awesome, thank you! That’s really helpful to know. The context is over here https://news.ycombinator.com/item?id=36613343 but it’s basically 80 rigged characters with a dozen or so anims, along with normal/diffuse/specular maps. The aim is to distribute them as widely as possible into as many engines and programs as I can, but it’s been hard to figure out what people actually use for their art and engine pipelines nowadays. I’ll prioritize gltf.
