Remarks
Creates a transient render target of the proper size/format/... or returns the existing one if it's compatible. InRenderTarget is read-only so it's up to the caller to decide to update or not the RT. Usually, the calling code will be : RT = FWaterUtils::GetOrCreateTransientRenderTarget2D(RT, ...) a compatible transient render target if InMaterialInterface is size/format/... is valid, nullptr otherwise
Parameters
| Name | Description |
|---|---|
| InRenderTarget | is the current render target currently used. It will be the one returned if it's already compatible with the size/format/... |
| InRenderTargetName | is the UObject's name in case we need to create a MID |
| InSize | is the render target's size |
| InSlices | is the number of slices of the render target |
| InFormat | is the render target's format |
| InClearColor | is the render target's default clear color |
| bInAutoGenerateMipMaps | is for generating mipmaps automatically after rendering to the render target |
