I was trying to do some overlapping alpha mapped 'grass edges' to break up the harsh edges on walls. it works fine , but when the lightmap is overlayed , the alpha is destroyed. where it should be transparent it is white. is there a work around for this?

I don't think there is I remember something like this turning up in the bug reports...

aghhh, bang goes my nice fluffy looking grass. just spent two hours on that bugger also I have problem with sprites, the transparency is not total, ie you can still see the poly , though only faintly . obviously this is no good. my sprites background is coloured black,0,0,0

That's a fog issue... Autofade your sprites so they don't ever touch the fog and you'll be alright.

thanks rob, thats a big help

I fixed it with entity fx,8 which disbales fog.
