Hi there!
I want to try out the wolf's light pre pass rendering.
And I don't know how to blend light datas into one texture.
I did is so in my "engine":
In that way I can't get the right result I want.
Does Anyone know how to put the all of the lights into the light buffer?
How to tell the shader not to overwrite, but blend the new color woth the old one?
