Hello!
I need to launch app on pc with integrated graphics card, that doesn't support glsl version 330. So I compiled osgearth with OSG_GLES3_AVAILABLE (300 ES - max supported version) defined. When I run app (using REX engine), I get following errors (on pic below). And earth is white and no layers are displayed. Same result in osgearth_viewer.exe
How can I solve this problem?
P.S. Also I've compiled with OSG_GLES2_AVAILABLE. Nothing has changed.
