-Moved the Eiffel Tower to a more cinematic position in the skybox
-Overall lighting improvements
-Fixed some props having strange render layer issues
I assume this is a model using $alphatest? Anti aliasing doesnt apply on a texture level afaik so it could be that. Despite that, yeah the beams are very thin.
I really think you should simplify this model into smth less noisy.
TF2 tends to simplify otherwise complex details like this (especially distant ones) into thicker, less detailed cards
Something like this might be more appropriate.
