There seems to be an uptick in Political comments in recent months. Those of us who are long time members of the site know that Political and Religious content has been banned for years. Nothing has changed. Please leave all political and religious comments out of the forums.
If you recently joined the forums you were not presented with this restriction in the terms of service. This was due to a conversion error when we went from vBulletin to Xenforo. We have updated our terms of service to reflect these corrections.
Please note any post refering to a politician will be considered political even if it is intended to be humor. Our experience is these topics have a way of dividing the forums and causing deep resentment among members. It is a poison to the community. We appreciate compliance with the rules.

You need to open the sca file and manually modify the code to tell the game to load your texture as a poly and then compile it to a bgl with SCASM. Did you do that? FSSC does not compile the bgl so a poly texture will show. You get a solid color square.
Download Cody Coyote's Blended Airfield Tutorial and follow his instructions if you aren't already.
Good luck.
