Summary: Texture lookup in vertex shader broken Product: Mesa Version: git Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: s3734770@mail.zih.tu-dresden.de
I ran the demo mesa-demos/src/glsl/vert-tex and fetch instructions only return memory garbage.
The same problem appears when running games via wine where hardware skinned models are not shown (better: vertices are spread around the whole coordinate system)

--- Comment #1 from s3734770@mail.zih.tu-dresden.de 2011-03-12 09:14:52 PST --- An additional info: the texture to fetch has float texels and is a luminance texture.

Patch: also regard vs resources
I found the problem: 077c448d184799e0d9ec962013ec784c6a5c1807 did not pay attention at vs The fix also adds the resource offset to vs
