eh!? How are you doing that without deferred?

You can pass a large number of light data to you shader. You have to define a max light count and initialize arrays with that value. Then in the app, you pass the current light count. https://github.com/demonixis/C3DE/blob/develop/C3DE.Content/Shaders/Forward/PBR.fx#L27 …

Dang! How is Unity doing that, normally with a forward render you can get maybe 4 lights in a shader before you start killing the GPU with calculation cycles... I also thought there was a limit on the registry making this not possible... But then my experience is rooted in DX 9

It's done in monogame but Unity Charles Would be interesting to see if this could be translated to unity, or if Unity had a similar solution

Yea, spotted that later on, It's interesting as I thought >3/4 lights in a forward render tends to kill the GPU, especially as you increase the number of objects to be lit in the scene.

Many of the hard limits are gone and it’s just down to GPU perf which has come a long way since those limits mattered. As long as you aren’t doing multiple passes you can get away with a lot. Not the most optimal way to do it though, that’s why alt techniques still exist.
