Title: Shading Issue
Post by: Birel-Rotax 42 on September 29, 2013, 05:53:49 PM
I have no easy way to explain what has happened, but when KRP is open, the preview of the kart is a bit odd. The shadows are funky both on the track and in the viewer. It happens on all karts, and I have uninstalled twice with no success. Can anybody help me troubleshoot this?

Did you update your graphic driver? I had the same problem after updated it. Try to downgrade it.

It is a known problem with AMD OpenGL drivers.
The issue is under investigation.
In the meantime, a workaround is to downgrade to a previous, correctly working, graphics driver.

That explains it, as I just upgraded to a second 7870 in crossfire, so new drivers were necessary. Thanks for the quick reply! You guys are the best!

The issue has been investigated, but no solution was found.
The driver doesn't report any error in the shaders.
GPU ShaderAnalyzer and gDebugger don't report any error either.
Trying to change the shaders' code to isolate the bug led to inconsistent behaviour.
So unfortunately the only solution at the moment is still to downgrade to a previous version of the drivers, until AMD will fix OpenGL support.

See my post here, neat workaround for the issue (assuming it is the same problem we see in GP Bikes): http://forum.kartracing-pro.com/index.php?topic=3303.msg29786#msg29786 (http://forum.kartracing-pro.com/index.php?topic=3303.msg29786#msg29786)

Shaders are all right with the newest Catalyst 13.12 drivers. :D
