X-Git-Tag: xonotic-v0.6.0~60 X-Git-Url: https://git.rm.cloudns.org/?a=commitdiff_plain;h=ded870ff9ce1f5b3b156cd33c04c67618feeba99;p=xonotic%2Fdarkplaces.git flip dpsoftrast's texture memory layout so it matches the framebuffer orientation (allows r_viewfbo and r_bloom to work) however, r_viewfbo and r_bloom in combination are still broken on GPUs/dpsoftrast without non-power-of-2 textures due to not matching the position DP's bloom expects them to be located at git-svn-id: svn://svn.icculus.org/twilight/trunk/darkplaces@11649 d7cf8633-e32d-0410-b094-e92efae38249 ::stable-branch::merge=e362fefcd05e3d1c5a8e5987916085de5cc368c5 --- diff --git a/dpsoftrast.c b/dpsoftrast.c index a79a9d36..a646db35 100644 --- a/dpsoftrast.c +++ b/dpsoftrast.c @@ -748,12 +748,12 @@ void DPSOFTRAST_Texture_UpdatePartial(int index, int mip, const unsigned char *p DPSOFTRAST_Flush();
