The game expects shadow sampling from a non-depth texture to silently fallback to ordinary sampling, and it expects this behavior because that's what the real vendor drives do in this circumstance. This is very easy to observe even without using apitrace and looking at components of the FBO: just create a box with the wizard character and watch the gears animate -- they'll pulse between dark and glowing instead of being correctly lit by the light sources in the scene. You can see this by comparing the first two screenshots attached to this bug -- in the Catalyst rendered scene, the cubes in the lower right are lit by the adjacent light, in the Mesa scene they're essentially random.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
