A few hooks aren't working.

CalcView and Pre/PostDrawOpaque won’t work for me. I even hooked them in a PostGamemodeLoaded hook and still nothing! No errors.

Entity:DrawShadow(bool) won’t work either. If I use Entity:SetNoDraw(bool) that will work, but then nothing draws.

Could someone else try and see if it’s working for them, because they aren’t working for me.

I use CalcView in my gamemode and it works fine, I haven’t tried the other things you’ve mentioned though.

I’ve been having trouble with DrawShadow also…
