Hi, I have been trying to convert my application to use version 1.50 compliant shaders and found that they work on my NVidia machine, but not on my ATI Mobility Radeon HD 5850 laptop. The shaders compile and link on the ATI, but no geometry gets rendered. Both machines are running Ubuntu 11.10 64 bit and the ATI drivers are the latest available. OSG version is 3.1.1 (developer release) / trunk (I've been trying both).
The same issue can be seen using the osgsimplegl3 example. If I execute ./osgsimplegl3 cow.osg the NVidia desktop machine shows the cow, while the ATI machine shows an empty window. osgsimplegl3 was executed after "export OSG_NOTIFY_LEVEL=INFO" and the 2 logs are attached. I would like to use version 1.40+ shaders to make potential porting to ES2 devices easier in the future. In any case, osgsimplegl3 example should work on ATI cards. I am quite new to shader coding and this has me thoroughly confused. Any help would be much appreciated. Thank you!
