Now sure if this is possible but one way that we could get some optimizing done would be to disable LightDir shadows from certain objects group?
So what I'm asking is if this would anyway be bossible to seperate dir light shadows in drawShadow function so that some objects only cast shadows for instance from cone lights.?
Thanks

you can do that manually, detect LightCur/CurLight.type in drawShadow

OH nice!
