Hi Robert,

J-S could you explain what made you suggest this in the first place?

I actually have no merit other than my memory being really good at times and really bad at others. I just remembered in this instance that someone had suggested that they had needed to reverse the t-direction in the shadow shader for osgShadow::ShadowMap to work on their ATI card (on this very list) and just repeated that information.

I'm sure a search through the list archives could turn up the original post, but perhaps someone else has some information...

I think it's a known bug, yes. Perhaps it just affects shadow2DProj samplers, and so is why other textures work correctly whereas ShadowMap needs reversed t coordinates? (just speculating...)

Sorry I can't help more,

J-S
