Variables

  Type Name Description
Public variable bool bAlphaToCoverageEnabled  
Public variable bool bAnyDirtyGraphicsUniformBuffers Bit array to track which uniform buffers have changed since the last draw call.
Public variable bool[SF_NumStandardFrequencies] bAnyDirtyRealUniformBuffers Array to track if any real (not emulated) uniform buffers have been bound since the last draw call
Public variable bool bFramebufferSetupInvalid  
Public variable FOpenGLBlendStateData BlendState  
Public variable TRefCountPtr< FOpenGLBoundShaderState > BoundShaderState  
Public variable FRHIUniformBuffer *[SF_NumStandardFrequencies][MAX_UNIFORM_BUFFERS_PER_SHADER_STAGE] BoundUniformBuffers Track the currently bound uniform buffers.

 AB: moved from the header, since it was causing linker error when the header is included externally.

Constants

Name Description
MAX_UNIFORM_BUFFERS_PER_SHADER_STAGE The RHI does not allow more than 14 constant buffers per shader stage due to D3D11 limits.
