Is this GitHub for all mods combined?

yes

Cause I have a question about the dynamic lights mod. Is there a setting or way for me to change the lights type (fancy fast etc)?

You mean on top of the Minecraft option itself? no

What about in general or the config file or something?

No, the mod does not add new light options to minecraft.

I dont follow. Dynamic Lights is not implementing a seperate light engine that could be configured. It uses the minecraft light engine which you can set to fancy in ingame options, and that is it.

Cause I'm on the 1.6.4 version of the mod and in the Minecraft settings there's no options for fancy etc.

No, the mod does not add new light options to minecraft.

So on my version of it I won't be able to change it?

Would you be be willing to add that option in a later update of it? If so I'm hoping all the versions will have it and not only the newer ones.

No, the mod does not add new light options to minecraft.

So it won't be possible add that feature in a next update and the mod can't support that feature?
