SpawnAssets.uasset (158.6 KB)
Here is the script we created. It spawns all static, skeletal meshes and niagara systems in a grid, scaled to a uniform size at the world origin.
Import the assets, right click and “Run Editor Utility Widget”. Then press the massive button.
You can then use this level on startup to precompile all your Materials, assuming you have them assigned to your source meshes.
If you did not, you would need to extend the script to apply the materials manually.
