Okay. So I go to Tools>Map Maker, yeah?
And when I click the 'Map Maker' button, this pops up:
OGRE EXCEPTION(5:ItemIdentityException): Cannot locate a resource group called 'Terrains/temp' for resource 'tempTerrain.material' in ResourceGroupManager::openResource at c:\Ogre_161_tag\OgreMain\src\OgreResourceGroupManager.cpp (line 685)
Could anyone help with this?
