hello,
just got a chance to check if i was doing something wrong... i managed to see that the installer had placed the files in the original houdini after installing
C:\Users\[username]\MyDocument\houdini16.5
under docs rather than the
C:\Users\[username]\houdini16.5
which i currently use... so my bad i guess, i managed to do a test (included grab) and i can create a substance shop and assign to a material.
thanks
