not familiar with irrlichtNX red :( as for the mac version... as far as i know there still is not a mac port. also, i have been thinking and have decided to stay the course since going back now will take significant time. if all goes well with my time in a couple weeks i should have a working irrlicht mod with the irrlicht distribution samples converted. on a side note, the irrlicht mod im doing is actually broken into 2 mods, similar to blitzmax opengl support. the base mod has the irrlicht engine wrapped up and exposes the wrap functions with extern, while the second mod implements blitzmax types for the irrlicht engine.
