I can help the best I can, some might be inaccurate and some utter bullshit.
1. hard to say without looking at code. the stuff you want be done client side (functions) need to be defined simulated.
2. Im noob enough not to know whata mesh is... If texture is needed, you could use "#exec import texture", havent found a place where its parameters are defined though.
Im talking Night and Day Udu. I sent you link to the code some weeks ago (3 i think). Ill mail it to Druid too, so he can look at it too.
With the light not being sent proper I mean, all clients are strange black (like the movie -pitched black) and it sucks.
I have been doing meshes for the shrine codes in the mod, and I know meshes can be imported, but not how :/ Im am currently focusing on shrine, SemiGod and player models, so that that can be done. Then Ill make skins for it.
Zodiak and Evildick are great aiders in this I must say. So models and maps will complete first it seems. Then I will, if no one else have the time, learn the suckery scripting myself. But aid would speed it up by at least 2 years
