> it turns out those are more explosive-barrel sprites, just squished down real thin. It turns out the Build engine was designed so that if you make sprites super thin, they just don't render. A small correction. If I remember correctly, this was a special property of that specific sprite - possibly hard coded in the engine, not sure. But only those specific gas bottles were rendered invisible if you reduced their width. Most likely specifically to make it possible to do effects like the exploding fan. Other sprites could be thin and render just fine - you can see that with palm stalks, traffic sign poles and things like that. Those are often just very elongated sprites.
