If you use SoftRenderer, play around with LightLinkings: whatever object or light-centric, it depends only on the way you understand things.
Then you'll have the control you want

Imagine you got some table lamp on a desk.
You'll put, of course, some point light where the lamp really is irl. You have some rendering with default intensity and notice that close area fits what you want but 95% of the room is totally dark, or lot more than you would. Of course activating photons calculation is out of question. So how the hell ?

Increasing intensity would be the solution for the room, but what about the desk, bleeding will be too intensive. No way then ? Yes, there is :

- Set a pointLight1 object centric on table+room with shads, set it quadratric. Control the bleeding on desk here.
- Set the second pointLight2 object centric on the room only, and set with this one the global lighting you would. You can, to have more control, have this global light as spot, e.g. if you want more global light on the floor than on roof. And once more, splitting there with UP and DOWN-ligting. Set these linear to prevent adding toooo much lights for final result.

pointL1 & pointL2 being at same world coodinates is not always true. It depends on what directly surrounds the light1. As you got a desk under light1, would be more close to reality to raise the light2 a bit.

And so on with the other lights and bounces when the scene gets more complex..


Window >> Relationship editors >> Light Linking >> obj or light centric. There you select a node on the left panel, it will show you the corresponding activated links. Simply click to add/remove a link.

Hope that helps.

Play around with it, there's a great part of powah in there :bandit:

But you absolutely got to work in the order of bounce lights and understand what your doing. That's a good way to me for faking GI with SoftRenderer.

>> get the last three to see what means understanding bounces. Ok that's explained for MAX, but these are concepts guidelines.


Who said : "Split .... if you want control !!!" :blush:
