Hi Stephan

I got round to trying FBOs with the modification you suggested. Here's what
I ended up using as GLES2 doesn't use the OES suffix.
#if defined(OSG_GLES1_AVAILABLE) || defined(OSG_GLES2_AVAILABLE)
#if defined(OSG_GLES1_AVAILABLE)
#define LOAD_FBO_EXT(name) setGLExtensionFuncPtr(name, (#name), (
std::string(#name)+std::string("OES") ).c_str() )
#else
#define LOAD_FBO_EXT(name) setGLExtensionFuncPtr(name, (#name),
std::string(#name).c_str() )
#endif
#else
#define LOAD_FBO_EXT(name) setGLExtensionFuncPtr(name, (#name), (
std::string(#name)+std::string("EXT") ).c_str() )
#endif
I've got no Idea if the whole OES thing is iOs specific or not.
Any how, it hasn't worked but I'm only getting one complaint
Error: glDrawBuffers not supported by OpenGL driver
I've made a simple example that is attached and I've also attached the full
log with debug_fp set. Bear in mind i'm using GLES2 so there's some shader
gen stuff that shouldn't be relevant.
I'm gonna continue digging but would really appreciate if you could lend a
hand. Once this is working I think we have the full set of features I
commonly use in OSG all working for IPhone. Yippee
