As a part of our pipeline, we’re pre-computing the lighting information into the vertices. That works fine. So at runtime, the textures are multiplied with the vertex colors
Now, I’d like to add a few dynamic (realtime) lights to this scene.
So what I would like to get is: the light contribution of the realtime lights should be added to the vertex color, and the total of that should be modulated by the texture.
Currently, panda does a multiplication of vertex colors and lights, so in effect my lights usually make things darker instead of brighter.
Is there a way to achieve this, without using shaders?
I was thinking along the lines of using the vertex colors as emissive part of the GL_COLOR_MATERIAL or so, but I’m not sure if that would work in the first place, and further I don’t know how to tell panda to do such a thing.
Any ideas anyone?
