If they use alot of shaders in their map or using all the features of the editor in a certain area, for some reason the editor just crashes on loading in the assets and then crashed on compiling all the shaders… It also crashes on compressing textures as it did with Infiltrator demo. I had this problem with trying to open up Infiltrator and also in trying to load the shooter demo map. I couldn’t even load them in the editor without the editor always coming up with a big crash screen Because the’re probably using bloom, too many post processing lighting effects, maybe there’s too many shaders and so on maybe using either stellar or set to high quality for textures that will crash the editor on my machine as I only have 16 gb of ram.
You may have to drop the quality settings to the bare minimum first in order to stop the editor from crashing when trying to migrate. Slow Motion can also crash it .
When i load my game map in the editor, it loads fine because I don’t use alot of shaders and I disabled all the bloom… I suspect that if you try to use alot of the editor’s powerful lighting features or shaders in one particular area of the map, or have a ton of shaders in one area
it will cause it to crash. the editor can’t handle trying to process everything all at once.
I found that out when I put a simple glow light material on many objects I had in my map and up popped the crash screen after rendering all the glowing objects. So there are limits to what the editor can handle before it keels all over and just capsizes.
