Hey guys. I'm new here. I've been messing around with CC3 and I'm getting kinda frustrated. Here's my problem. After laying out my land mass I lay out contours for snowy area's and some bodies of water using the sea contour but when I use the sheet tool to add stuff like blurs or glows it erase my contours and I can't figure out why. I've been at this for about 4 hours and I'm lost. Can anybody help?
