[Opensim-users] OS0.7.3.1 and SL3.28 produces gray textures

[99miata Owner]

When using OS 0.7.3.1 and SL3.28 I see gray textures, ground cover,
and no meshies.

When using OS 0.7.3.1 SL1.23 I see colorful textures, normal Linden
ground cover, and (of course) no meshies.

What Config setting(s) might I have falsely set to cause this problem.
