Alright I think IÂm back on track now.
I kept trying different things and the program just kept crapping out. Then I had a great idea.
I went to file/export and exported the whole model and all its materials to .3ds format. Then I imported that new .3ds file into Zmodeler and it seems to be working fine now. It was getting so bad that I couldnÂt even open then close the program without seeing an error message.
I guess the file size wasn't the problem after all.
But we all have Dyne to thank. Because .3ds format is what I made the model into before sending a copy to him so if it werenÂt for Dyne I wouldnÂt have even thought about putting the model into .3ds format.
The only bad part is when I put the model into .3ds format the shading got changed around but that doesnÂt really matter because IÂm going to be redoing the shading later.
Having the shading messed up some is a small price to pay compared to almost loosing 2 and half years of hard work. It's too bad I spent my weekend trying to get the program to work when I could have been getting work done on the model.
Here is what I was in the middle of when the program started crashing. I was making the grill 3D.
