Hello again. Different problem this time, so different thread.
I believe there is a bug in node.c when evaluating node->scl from the
scl_track. It uses lib3ds_lin3_track_eval() which, if the track is
null, sets the scale to (0,0,0). It would be better if it defaulted to
(1,1,1) when no track exists.
Here's my patch, though I haven't tested it properly yet cos of my
build problems. I'm pretty sure it'll work though. FYI, Sketchup's 3ds
export tends to forget to put a scale track in the node. That's how I
spotted this.
