UKismetRenderingLibrary::ResizeRenderTarget2D

Access: public
Specifiers: staticUFUNCTIONBlueprintCallable
Description
Changes the resolution of an existing render target, useful when the game viewport size or in-game resolution changes at runtime.
Caveats & Gotchas
- • Resizing reallocates the underlying GPU resource, discarding any previously rendered contents — clear or redraw the target afterward.
- • Calling this every frame (e.g. to match a constantly-changing size) is wasteful; only call it when the target size actually needs to change.
- • If Width or Height matches the current size, the engine still performs the update path rather than skipping it, so avoid calling it redundantly in a loop.
