ok explain this marshmellow stuff madness xD

Oh gosh X3 It looks like you're missing a texture file that goes along with those meshes. Possibly the creator didn't include it in the download on accident?

Looks like it rained marshmallows, lol! But when something turns up white, its the game looking for a file that doesnt exist. Make sure you dont have any typos in your file name. Also make sure its the right file type, and the creator may have put typos by accident, you would have to get rid of them.~

I'll be moving this over to the Game Help board, as you are seeking assistance for a problem with your game. The Game Discussion board is geared toward a discussion and collection of thoughts over a topic involving the game but not necessarily focused on fixing a bug or troubleshooting.~

First thing that I would recommend would be to reinstall the map from the .zip file you downloaded of it. If a dialog box pops up asking if you'd like to replace any files in the "exports" folder, allow it to replace those files. It's likely a material file isn't being found by the game. ^^
If a reinstall of all of the map files from the .zip doesn't help, then it's more likely to be a problem on the creator of the map's side.
