UMaterialInterface

Importing data and options used for this material

Array of user data stored with the asset

Whether this material interface is included in the base game (and not in a DLC)

Set if CachedExpressionData was loaded from disk, should typically be true when running with cooked data, and false in the editor

Because of redirector, the texture names need to be resorted at each load in case they changed.

Cached data generated from the material's expressions, may be nullptr UMaterials should always have cached data UMaterialInstances will have cached data if they have overriden material layers (possibly for other reasons in the future)

Get the value of the given static switch parameter

Returns the density of a texture in (LocalSpace Unit / Texture).

Get all of the textures in the expression chain for the given property (ie fill in the given array with all textures in the chain).

Accessor to the data.

Return the textures used to render this material.

Return the textures used to render this material and the material indices bound to each.

Returns whether there is any streaming data in the component.

Initializes all default materials.

Checks to see if this material has all its shaders cached.

Test this material for dependency on a given material.

Same as above, but can be called concurrently

Checks to see if an input property should be active, based on the state of the material
