Try search over map vault

Decal limit have nothing to do with blinking decals You can also try to change the sun direction, power to fix that shadow issue

Finally i see who knows what he is trying to do. Nice work Jip but i don't think so it's a good idea to using a over +80Mb decals files over the map, also i don't think so that it's the correct way to make maps. Every time when unit's shoot the ground etc..... it will draw a new decal over your ''masked decal'', later or sooner the decals start blink..... and in worst case it will crash the game, other wise great work. Also some terrain fixes could fix these shadows in some area and gives a better picture while zooming
