we could just render them classic way with all solid geometry in a gl list
and all transparent geometry in back to front order... all alpha settings
should be normal. I have used this for rendering transparent map geometry in
phase1... do you remember?

there are some good papers about dynamic lod... I am not thinking about
using DLOD models right in the engine but about using DLOD mechanism in
converter tool. This tool should save all lods same way as mipmaps are
saved.

I have already done it. Also multiplanar panel lists work now very
well...hmm... they aren't processed as single bucket but each triangle
generates a bucket.
