You could have a brick object that creates a flower at it's position, then destroys itself.
I have spoken to both Ephiliates and Badspot briefly on the idea of using DTS shapes as pseudobricks but both maintained the same stance. Essentially they both said that using a DTS shape would be a step backwards towards the 0002 version which did use DTS shapes for bricks. The same concept applies, too many DTS shapes can lead to lag.
I suggested limitations on the special DTS bricks per player or per server (like vehicles) but no compromise could be met. As it stands, the only way to currently make a new complex brick is to write the coordinates out by hand.
Anyway, back on topic. I have been experimenting with the heightmap feature which generates the terrain from a png file. Its working fine, but the mission editor really over exaggerates the various heights, so what was supposed to be a relatively low lying map ended up being a series of canyons. I'm torn between making a new heightmap from scratch or just going with whatever the editor spits out. Problem is that cliffs look rather ugly in TGE.
