So I've collected some knowledge from various locations around the net. Starting first and foremost with this tutorial by Noesis: http://www.moddb.com/engines/source...stom-props-for-source-powered-games-with-maya And a few weeks back I successfully completed the tutorial and happily had the skull in game. Buuuuuuuuuuut, now I can't get a damn thing to work and I can't figure out what I'm doing wrong. So I'm using the prall exporter from maya and that seems to be a part of the problem, here's a comparison. I had to put these as attachments because it's a lot of text. Looking first at the good compile; Its happily detected that the physics model is a load of crap, compiled the smds and so on. Now looking at the bad compile; It's not even noticed any problems with the physics model and so many fields are listed as 0 bytes when they shouldn't be. Something is wrong with my smds. Anyone whose had experience working with importing custom models, how are you creating your smds? Using the prall plugin for maya, can you think of what I'm missing here? etc. ANY help is appreciated, I've been pulling my hair out over this for a while now but I just can't figure it out.
