X_SCALEMODEL obj% scx#,scy#,scz#
Multiplies the dimensions of the model with scx, scy, scz factors. The real model is scaled, so you can draw it with X_SCALING 1,1,1 later. The advantage is that X_SCALING 1,1,1 allows the X_COLLISION, shadow and bump mapping effects to work properly.
This command might take some time.
