Hi Janbo,
I don't care about the shadow - rather, I just want to light the specific object with the shader and not unintended items.
I wouldn't have the point light in the scene, just in the shader so I expect to just be able to apply the shader to the lift and meshes of my choice to light according to the shader specific point light.
The "top of the lift shaft" will be lit normally by the scene lights only and not be affected.
Surely if I only apply the shader to the objects I want to light with the in-shader light, then that is all that would be affected?
Green Gandalf's shader example on here (the 144 lights one) would have been ideal, but doesn't work properly for me. I did try to adjust it with your recommendations, but still no luck.
Similarly, the there are a number of shaders on the shader thread for lighting, but these don't work any more.
So, to recap: I think a shader which accepts input for ambient and sun values and texture0, and the ability to set a point light RGB and radius would be enough.
