This forum is for uploading new building blocks for maps such as tags and new models. Please do not post any copyrighted material (ie, models/textures from other games).
Alright I fixed your map and got it exported into a scenario. You had two problems. First you didnt delete the bottom faces off of your base and after I fixed that there were some overlaping triangles on the sky part where it meets the mountains(I have that happen alot when I rotate the faces to make my mountain ranges jagged). You didnt include your ground bitmap so to get it exported I just removed the bitmap and made a fake shader for it. Also you will need to go and make a shader enviroment for your ground bitmap and also the bitmap you used on your base. The download is the level to put in your data\levels folder and also the level to put into the tags\levels folder. Any other questions you can PM me and I can helo
