Adapative Light Solver and Portals

[dj_buckley]

So we know that the Adaptive Light Solver negates the need for portals.

But we also know that the Adaptive Light Solver can do some weird stuff at random times, a lot of the time when using Reflection Overrides.

So if I'm doing an interior with a Reflection Override - I tend to turn Adaptive Light Solver off, just so I don't come back to a finished render full of blocky artifacts.  It's safer.

But if I do that, turn ALS off, should I then revert back to using portals also?

These are two separate things:
1. Adaptive light solver (exposed in the Performance tab)
2. Adaptive environment sampler (hidden in the devel rollout)

The adaptive environment sampler is the one that replaced portals.

In Corona 6 and newer even if you create a portal or if you load an older scene with a portal mtl, it will be completely ignored, just as if it would not exist at all.
Portals will not be rendered and will not affect rendering in any way regardless of the adaptive environment sampler state.

Ah ok, that clears that up then, thanks
