MATERIAL_TEXTURE_STREAMING_DATA_VERSION

#define MATERIAL_TEXTURE_STREAMING_DATA_VERSION   1

This is used to deprecate data that has been built with older versions. To regenerate the data, commands like "BUILDMATERIALTEXTURESTREAMINGDATA" can be used in the editor. Ideally the data would be stored the DDC instead of the asset, but this is not yet possible because it requires the GPU.

Function Documentation

DoesMaterialUseTexture()

bool DoesMaterialUseTexture	(	const UMaterialInterface *	Material,
		const UTexture *	CheckTexture
	)

Check whether the specified texture is needed to render the material instance.

Parameters

Texture

The texture to check.

Returns

bool - true if the material uses the specified texture.
