I found a bug when exporting headlights in 2.17 version. When I make a headlight object with a material with 2 textures "hlglo00" and "hlglo01", whose properties are "animation = event 0,1", and I put transparency setting to "none", it works in game properly.. But since I must have the transparency in game for the "hlglo00" texture not to be black, I chose "simple" or "multiple" in transparency options.. But then, not even the texture "hlglo01" works in game.. Just nothing visually happens when I turn on lights..

I did completely the same thing on my previous mod and it worked..
I spent couple of hours trying to solve this problem.. I tried adding white alpha to "hlglo01" tried various functions in 3dsimed.. But nothing worked.. Then I remembered I used some older version of 3dsimed for my previous mod..

I tried exporting in version 2.6a and it worked! Just as in the old mod... So apparently something's wrong with the newer version..
