Well i had already did that, but i know why it didn't work the first time... i didn't turn the image in to a PNG. image. So yea that was my fault. Thanks though.
New but small problem- When i make my bitmap and load it on to the terrain with mission editor, not all of the bitmap image looks like it came out to big. I tried sizing the image down to 512x512, but it didn't really help. Did i miss something? (I'm using Geocontrol)
