| Summary | 0003107: Shadow FBO setup incompatible with OSX/ati | ||||
| Description | ShadowHandler.cpp was ejecting "GL_FRAMEBUFFER_UNSUPPORTED_EXT" on me, so I changed the FBO setup in InitDepthTarget(), and did two things: 1. Used GL_CLAMP_TO_EDGE instead of GL_CLAMP_TO_BORDER in texture creation, otherwise the FBO will simply fail: https://github.com/spring/spring/blob/88.0/rts/Rendering/ShadowHandler.cpp#L227 2. Must have AtiHacks = 0 I was getting mixed results messing about with the depth buffer bits, so I'm not confident to say what's going on there. BTW, "GL_NEAREST" really sped up things, but had no effect on the acceptance of FBO buffer format. Applicable file: ShadowHandler.cpp, in CShadowHandler::InitDepthTarget() my springrc: AtiHacks = 0 LoadingMT = 0 Shadows = 1 with AtiHacks on or as -1, it doesn't work. Probably because of the color texture attaching, which ejects a "FBO-SHADOW: no/unsupported textures/buffers attached!" error. long story short, GL_CLAMP_TO_EDGE is the magic in my case. I'm on 10.6, with an ati 5670. 32 bit kernel with 64 bit spring compile. | ||||
