I noticed there’s a comma at the end of rdb’s link in that thread. Think that messed up the file download or something. The one I got originally was only like 300+ bytes. Removed the comma and got a 28k file, and now it looks like packp3d is working. I’m getting errors building my .p3d file, so I’ll go through those and try to clear up anything related to my code. Thanks for your help!
