I made a transparent material but I cant get light to pass through it from one side to the other.
Does anyone know if there is any trick to making lightmass work with a transparent material?

Is
that
what you're looking for, or
this
?
so I guess:
Lit materials
BLEND_Translucent and BLEND_Additive: Transmission = Lerp(White, Diffuse, Opacity)
BLEND_Modulate: Transmission = Diffuse
BLEND_Masked
Unlit materials
BLEND_Translucent and BLEND_Additive: Transmission = Lerp(White, Emissive, Opacity)
BLEND_Modulate: Transmission = Emissive
BLEND_Masked

Perfect Ben I had a go re-creating "
this
" :P and got it working with your setup. Not sure what I was doing wrong the first time around if I figure it out I will post back here.
As always you've been a huge help thanks a bunch!
