static UMaterialInstanceDynamic * GetOrCreateTransientMID
(
UMaterialInstanceDynamic * InMID,
FName InMIDName,
UMaterialInterface * InMaterialInterface,
EObjectFlags InAdditionalObjectFlags
)
Remarks
Creates a transient UMaterialInstanceDynamic out of the material interface in input or returns the existing one if it's compatible (same parent material) a compatible transient MID if InMaterialInterface is valid, nullptr otherwise
Parameters
| Name | Description |
|---|---|
| InMID | is the current MID currently used. It will be the one returned if it's already compatible with InMaterialInterface |
| InMIDName | is the UObject's name in case we need to create a MID |
| InMaterialInterface | is the parent material interface of the desired MID: can be a UMaterial or UMaterialInstanceConstant, in which case a MID can be created, or a UMaterialInstanceDynamic, which will just be returned as-is (as we can't create MID out of another). In the latter case, it is expected to be a transient MID. InMID is read-only so it's up to the caller to decide to update or not the MID. Usually, the calling code will be : MID = FWaterUtils::GetOrCreateTransientMID(MID, ...) |
| InAdditionalObjectFlags | is the additional flags that should be set on the newly-created object, if any (it will come out with at least RF_Transient as the name of the function implies) |
