bump mapping on ati cards

[wolverine1974]

I know the threads are there for this topic but I thought a clean thread just for ATI users would be nice for ati trouble shooting. Anyone using ati card and got bump mapping to work would be great if you posted here and explain what you did. also the different os's as well (xp, vista, win7 and 32 and 64bit)

hopefully this will help resolve this issue and give some people a place to start for a fix. cheers:D

Just so you know, bump mapping doesn't actually work on nVidia cards either.

You can select medium/high and the game doesn't crash like it used to, but the rendering either isn't actually any different than bumpmapping on low or if the bumpmapping does display, it's weird and corrupted looking.

The game used some old vendor-specific API commands that aren't supported by modern video cards from either brand anymore. In short, there's no way to fix as it's something coded into the game's engine. Just use the low setting.

yeah, i was kind of gathering that during my research but it always seems there is someone out there way smarter than me who finds fixes for these things, whether he be a coder, or sharp with ini file adjustments or nvidia and catalyst menu combinations to make certain things work. alot of the time fixes I get for games come from bright individuals who are not even tied to the companies who make the games so I just wanted to give them a place to post for fixes so others wouldn't need to comb through threads reading about how it doesn't work instead of getting to the actual fix. cheers.:)

Maybe a direct email to LucasArts tech support? I wasn't able to find an article in their knowledge base, but then I haven't much faith in tech support site search engines. On the other hand, I did try searching for this issue using four different combinations of keywords.

It's the game engine.
It wasn't supposed to support bump mapping.
But the developers found some odd way of making it support it.

Understood but in this case there is no fix. It would have been found long ago if there was.

The game makes some proprietary calls to implement bump mapping that are unsupported by modern video cards - so nothing short of stripping them out and rewriting the bump-mapping routines to use standard DirectX calls is going to fix that. Without access to the source code that could never happen.
