I think 3Impact game engine is behind 3drad. Is it possible to call 3impact dll which is in 3drad folder using idllcall Function. Do all 3impact functions are available? Can i get or send object handle to 3impact dll?
Some 3Impact functions are exposed in the scripitng interface. And yes, 3D Rad is written on top of 3Impact.
Unfortunately, you can't call 3Impact functions from iDllCall manually. You will need a secondary dll wrapper that is compatible with the 3D Rad function signature that is required by the iDllCall function.
