|Summary||0005022: Implement a forward+ render|
|Description||Right now TDM uses the original forward render of idtech4, this render, it seems, can support up to 64 point light sources (in a small demo scene, no AI, no physics) at above 60fps, this if they are small, that means they interact with few pixels and they cast no shadows. But in the future, TDM could theoretically support up to a million dynamic light sources, point and spot, by implementing a forward+ render, of course the same limitation as the normal forward render apply to shadow casting lights, the few the better.|
Here is the youtube video that made me write this:

|I believe the multi light shader supercedes this|
|You know best, was just a suggestion for the future. Btw what does the multi light shader do?|
It's supposed to render all lights in one pass, contrary to the original D3 implementation where each light required a separate pass
You can test it with r_testARBProgram 2 but it requires the shadow maps mode
Thanks for the info, not sure if is the same thing has a forward+ render but sounds interesting, will test it right away.
Btw makes me wonder, if doing them in one pass is faster, why did John Carmack made a pass for each light? Hardware limitation at the time? I'm not a graphics render guy so sorry if this question is obvious.
It's the only way stencil shadows could work back then in 2004 AFAIK. At that time stencil shadows made much more sense than now because of GPU limitations.
