How do you make stuff transparent?

[tachzusamm]

I know it does not sound logical, but I have a working setup with ZTransp OFF +( ZOffs=0) for the object to appear in front of the waveset (and passindex=3),
and ZTransp set, ZOffs=1, passindex=0 for the waveset.
Oh, and the object's texture has set Col + Alpha in the Map To panel.

There's just no general rule that works in all cases.

Let me refer to this thread, on the same topic (specifically, wavesets drawing in front of other stuff): http://forum.guildofwriters.com/viewtopic.php?f=59&t=2786

One of my posts there explains how Plasma sorts spans, and how you can override that.
