Structures

renderengine::ProgramBuffer

Offset	Length	Type	Name	Description	Comments
0x0	0x4	void*	m_programBuffer		Set at runtime? Sometimes filled with seemingly garbage bytes
0x4	0x4	uint32_t	m_programSize		Always 0. Set at runtime?
0x8	0x4	uint32_t	m_programOffset		Always 0. Set at runtime?
0xC	0x4	Type	m_programType	Shader type	Pixel or vertex shader
0x10	0x4	uint32_t	m_programFlags	Flags	See flags
0x14	0x4	CGprogram	m_cgProgramBuffer
0x18	0x4	uint32_t	m_cgProgramSize
0x1C	0x4	uint32_t	m_numParameters	Number of parameters
0x20	0x4	ParameterOffsetTable*	m_parameterOffsetTable	Parameter offset table	nullptr if vertex shader

Immediately followed by a set of ProgramVariableDescriptor entries of an amount defined by m_numParameters.

_CGprogram

No associated symbols.

Offset	Length	Type	Name	Description	Comments
0x0	0x4	uint32_t	?		Flag behaviour changes when 0x1B5C
0x4	0x4	uint32_t	?
0x8	0x4	uint32_t	?	Size	Same value as m_cgProgramSize in ProgramBuffer
0xC	0x4	uint32_t	?	Number of entries pointed to by 0x10
0x10	0x4	?*	?	Unknown 0	Relative to CGprogram start See unknown 0
0x14	0x4	uint32_t	?	Size of unknown 0
0x18	0x4	uint32_t	?	Size of unknown 1
0x1C	0x4	?*	?	Unknown 1	Relative to CGprogram start See unknown 1

renderengine::shaderpatch::ParameterOffsetTable

Offset	Length	Type	Name	Description	Comments
0x0	0x4	uint32_t	m_numParameters
0x4	0x4	uint32_t	m_size

This structure is immediately followed by a set of unknown structures of count m_numParameters:

Offset	Length	Type	Name	Description	Comments
0x0	0x4	uint32_t	?	Type?	1 or 2 in samples 0 if field at 0x8 is null
0x4	0x4	uint32_t	?		0 in samples
0x8	0x4	uint32_t*	?	Number of ?	Offset relative to ParameterOffsetTable start

There may be further data that is always null, but it is more likely the size is aligned 0x80.

renderengine::ProgramBuffer::ProgramVariableDescriptor

Offset	Length	Type	Name	Description	Comments
0x0	0x2	uint16_t	m_index
0x2	0x2	uint16_t	m_numConstants
0x4	0x2	uint16_t	m_dataType
0x6	0x2	uint16_t	m_cgParamIndex

Unknown 0

Offset	Length	Type	Name	Description	Comments
0x0	0x4	uint32_t	?
0x4	0x4	uint32_t	?
0x8	0x4	uint32_t	?		0x1005 or 0x1006 in samples
0xC	0x4	int32_t	?		-1 in samples
0x10	0x4	uint32_t	?	Name 1?	Points to a string in the following data
0x14	0x4	uint32_t	?		Points to an unknown data structure (vertices?) in the following data
0x18	0x4	uint32_t	?		Points to an unknown data structure (indices?) in the following data
0x1C	0x4	uint32_t	?	Name 2?	Points to a string in the following data
0x20	0x4	uint32_t	?
0x24	0x4	int32_t	?		0 or -1 in samples
0x28	0x4	uint32_t	?		1 in samples
0x2C	0x4	?	?		0 in samples
