- So we saw a quick difference between the Path Tracer,…the Low Caustics, and the Max Path Length.…So let's kick off an IPR render.…And let's kind of zoom out…to our camera view one.…And what happens if under the IPR tab…we switch to the VCM?…So right away we get a nicer more sort…of filled out light that we can see.…The Path Tracer was just quite noisy,…and the light got out,…but not as well, and look at the VCM.…
It's really doing what we're expected…because it is a bright light.…And it's just doing a nicer treatment…of that light onto the building.…So if we go back to a previous one,…well, we can just switch it here…in that same view…into the Path Tracer.…So we had the light coming out…just like in our example…with that Cornell box…with that frosted glass ball.…Remember that?…It was just very noisy and it wasn't finding it.…So the same thing because we have a light…inside some glass.…So if we do the VCM,…look at this.…
It's shooting light out from the actual light source.…It's going through and it's just doing…a better job finding that light source through there.…
