Detailed Description

Represents an .mtl instance that can be applied to geometry in the scene.

Member Function Documentation

◆ FillSurfaceTypeIds()

virtual int IMaterial::FillSurfaceTypeIds ( int  pSurfaceIdsTable[])
pure virtual

Fill an array of integeres representing surface ids of the sub materials or the material itself.

pSurfaceIdsTablePointer to the array of int with size enough to hold MAX_SUB_MATERIALS surface type ids.
Number of filled items.

◆ GetSafeSubMtl()

virtual IMaterial* IMaterial::GetSafeSubMtl ( int  nSlot)
pure virtual

Always get a valid material. If not multi material return this material. If Multi material return Default material if wrong id.

◆ GetShaderItem()

virtual SShaderItem& IMaterial::GetShaderItem ( int  nSubMtlSlot)
pure virtual

Returns shader item for correct sub material or for single material. Even if this is not sub material or nSubMtlSlot is invalid, it will return valid renderable shader item.

◆ GetTextureMemoryUsage()

virtual int IMaterial::GetTextureMemoryUsage ( ICrySizer *  pSizer,
int  nMatID = -1 
pure virtual

Estimates texture memory usage for this material. When nMatID is not negative only caluclate for one sub-material.

◆ SetFlags()

virtual void IMaterial::SetFlags ( int  flags)
pure virtual

Material flags.

See also

◆ SetMaterialLinkName()

virtual void IMaterial::SetMaterialLinkName ( const char *  name)
pure virtual

Set & retrieve a material link name. This value by itself is not used by the material system per-se and hence has no real effect However it is used on a higher level to tie related materials together, e.g. by procedural breakable glass to determine which material to switch to.

◆ SetSubMtl()

virtual void IMaterial::SetSubMtl ( int  nSlot,
IMaterial pMtl 
pure virtual

Assign material to the sub mtl slot. Must first allocate slots using SetSubMtlCount.

◆ SetSubMtlCount()

virtual void IMaterial::SetSubMtlCount ( int  numSubMtl)
pure virtual

Sub-material access. Sets number of child sub materials holded by this material.
