Well Havock can be used for non commercial things only !

For Nvidia Pysix, it could be implemented in A7 , i don't know why it is not planned frown
Even old and buggy engines have it implemented like Dark Basic Pro !
The problem, will we have tools to edit physic properties vissually ? i doubt 3DGS is lot more coder oriented than artist !!

Just do It !!
