this is a part of Houdini Engine code, use to write back landscape data from houdini to unreal, and the “FLandscapeEditDataInterface::SetAlphaData” method is TOO SLOW that each layer in 8k resolution costs 0.8 seconds to write back.
Moreover, I can’t use ParallelFor for this method, and I see this source code, this method does not use multithreaded in its interior.
Whether there is a way to improve the performance of write-back landscape data?
