If you attempt to use textures, you will have to not only use a float texture, you will have to fetch from that texture twice for every light. And if you compute all of the lights in one pass, that’s 200 texture fetches.

WebOur shaders are going to assume that there is only 1 active non-global ambient light. Legacy OpenGL allows at least 8 active lights, all of which would be involved in the ambient light calculations (when enabled).
