I've been playing around with generating normal maps over last few days and I've been hitting some strange problems:
First one is mentioned in the title, the models are .obj files exported from Maya (using the built in OBJ exporter). The "working" model (low detail) will load fine but even on very simple models it will fail to load the "reference" model (high detail). It just crashes and asks if I want to send an error report (that doesn't seem to contain anything useful at all). Has anybody used this tool with Maya? Do I need to find a .3ds exporter to make it work (i.e. their .obj loader is bugged) or might there be something else I'm missing?
Secondly the ATI normal mapping tool seems to be working somewhat better (I get output) but the normal maps on the final model seem to have stripes running through them (looks like possibly texture seems) and yes I did have edge padding turned on. I've also been getting some pretty garbled output about 50% of the time.
Lastly I tried the Maya built in tool (transfer surface information I think it's called) and that just gave me an error message saying that I must only have 2 objects selected even when I only had 2 objects selected.
So, has anybody got experience with this? Any tips you would like to share? Maybe some good links (I've googled the subject and most "tutorials" are basically a very simple explanation of what normal mapping is and hardly more).
