Covers setting up the decal render feature, configuring the decal shader graph with angle fade to prevent stretching at corners, and implementing an object pool in C# to manage hundreds of decal instances efficiently. Includes sphere casting for better normal interpolation at edges, coroutine-based fade-out and pool return logic, and GPU instancing for batched rendering. ## Full article daily.dev links to this article rather than hosting it.
