I’ve been looking for a way to set an ambient light for a scene and so far haven’t been able to find one. Using the material ambient values wouldn’t be very helpful as I want to have objects move between areas that would have different ambient light levels (or rather, different branches of the node tree). Also I don’t want to use the shadow systems, as I think it’d be too much of a performance hit.
I searched the forums and wiki, found a few possible solutions, and added my own, but they all have issues:
- Using another directional light opposed to the main scene light leaves areas perpendicular to the line darkened.
- Using the material ambient value isn’t great since it seems to be a multiplier of the diffuse light, and I’d rather it be a seperate colour.
- Using 6 directional lights arranged top/bottom/left/right/front/back is the closest to the effect I want to achieve, but leaves visible artifacts on surfaces with many polys (sphere in my tests).
- Writing a custom fragment shader, but I am new to GLSL and don’t know if you can pass variables to them like that, or even if that would be a sensible way to do it.
I read in one of the topics that the ambient light class was removed some time ago because it worked in a strange way - and the supposed replacement went with jme2. Is there a proper ambient lighting solution in jme3?
