Thanks for your query Tegurd.
Not any formal license here but basically with all the existing asset packs:
-any use in a derivative work - commercial or noncommercial, pretty much no restrictions on that and modifying the assets for a specific use case is fine or using assets unmodified, in a work that builds on them in some new way, new form like a game level, 3d art render, VFX shot or sequence, etc.
- no crediting of author required, but:
-only real restriction is don't redistribute entire asset collections as is or try to claim you made them, try simply to resell a pack I made, etc.
Essentially common sense applies and in most situations you will likely to be able to use this however you want to, but if a specific ambiguous case occurs you can certainly ask about it.
As for the query some may have: Yes, I do have plans to expand this pack a bit with a few more elements soon. But a few other things which are now nearly done are going to be prioritized and those updates released first. I am optimistic no fewer than five asset packs should be seeing updates in the next 12 days. Some useful new material is pretty close now.
