Help with Custom importing

[Deep Sea Kraken]

This is probably a stupid but but Ill give it a go: where can I dl custom material for landscapes/doodads and such? And how do I make them work? Ive tried to use some custom skins in a map of mine, I imported them and the file path works and in the import manager it says they are being used, but the esitor [and game] wont show them for some reason.

this is in the wrong section, but you can try the resource place here, just click on resources at the top tab or you can either get the wc3sear resource here:
