Hi Ello,
Thanks, I will try it out at this weekend. Yes, the error looks cool anyway

but Im afraid, I cant use it in this way.
Sorry I dont know how long it actualy needs to render those lights but I will ask my 3D designer aka Sinnlos

cheers and thanks again.

Edit:
Sorry Ive forgot to mention that the error is always there no matter what aa settings I use (2x, 4x, 8sx, 9x).
