I used MaterialX to render a very good rendering, how to bake the rendered image (such as color, normal, etc.) to the uv of the model and apply it to the game texture

One more point, if you need 5.2 PCG Graph to run smoothly, you need a good graphics card , it may be a good choice to strengthen the terrain erosion(Although more people in the current project use Gaea), Unreal has not yet done a similar function, but I really hope that Houdini and Unreal can interact and generate faster can improve.
It will take a few years for Unreal Engine 5.2 PCG Graph to be fully applied to the project after it is announced now (you can refer to Chaos)

Although PCG Graph supports the use of external input point clouds, the improvement of Unreal 5.2 PCG Graph is visible. This improvement is precisely the weakness of Houdini engine (a large number of PCG generation is slow and requires cook). Houdini engine first needs to improve PCG in unreal engine Generation speed (although somewhat difficult to achieve, the bottleneck is often HAPI and unreal data transfer).
