When playing with "Shaders For Warp Textures" enabled, textures can sometimes go a tad haywire and be "replaced" by the warp texture if the warp is viewed from certain angles.

Here's a screenshot:


Here's a (somewhat crappily compressed, I apologize, but you get the point of it) video:

My video card is a Radeon X1300, and I am using the official ATI drivers for Windows Vista, with a version number of 7.14.0010.0503 and a timestamp of 14/06/2007.

Any thoghts?

I had this same bug in skulltag in GL. It appears to be an ATI problem. NVidia cards do not suffer from this, and I have never seen it since I got my nvidia.

Other people with ATI have similar problems as this, as well. I dunno if it's just cuz of the driver, or a limitation of the ATI Hardware. ATI fails it in opengl , though, since it seems to be more for direct3d. NVidia is far more opengl compliant .

Anyways, that would probably be the issue.

Actually, even nVidia cards suffer the same problem.

It happens both on my older GeForce 4 MX and my newer SLI'ed 7950s.

I can't remember if Graf ever said about planning to fix it or anything like that but hopefully he would fix it eventually.

If you absolutely want to use the new warp shaders, you can turn off dynamic lighting. That'll make the glitches go away.

What's the difference with warp shaders anyway? I'm probably missing something.

Setting "Force Additive Lighting" to on also fixes the display problem, even with enabled "Shaders For Warp Textures". Unfortunately the additive lighting doesn't look right under some circumstances, so this is no solution either.

Yeah unfortunately, additive lighting is ugly.

The Kins: The shaders make WARP and WARP2 textures deform smoother and prettier. It's hard to describe the difference without an animation and I don't really have the resources to create one right now. But it's just nicer-looking.

EDIT: I just noticed that your hardware does indeed support shaders. Trying turning off dynamic lights temporarily then take a close hard look at warped textures and see the difference.

EDIT 2: I also just noticed that you're Kinsie. Sorry for treating you like a newbie.

After a quick check 1.0.25 seems to fix this completely for me.

The shader code was completely rewritten, both to enhance flexibility and to address the issues that caused this. Thanks for confirming.
