Anti aliasing area light

[doug1138]

I'm using Kray 2.2 with layout 2015.1

The render I'm getting is great except where the area light hits the wall. You can see aliasing or stepping in the image. I have the area light set to Compute with luminosity


It doesn't seem to matter what settings I change they remain consistent. Any tips on eliminating that?

Thanks
Doug

I may have answered my own question... I upped the light samples to 6 (in the render globals panel) and the problem seems to have cleared up.

In this corner You can use:
- Area Light (actual in scene) but then you must increase Area Light Quality and render long
- LEM - just luminosity panel - then is better render in QMC mode.

Here setting for minimum quality for Area Light:

Here maximum quality (over that is unprofitable raising amount of rays):

I suggest to use QMC system and LEM lights. In this moment the best option for rendering.

Thanks for the response.

Forgive my ignorance but I can't seem to find any info on LEM. Is that a KRAY thing? Or simply a luminous polygon in Lightwave?

LEM = Light Emitting Material = Luminous polygon in Lightwave

Here you have settings.

LEM:

If you want hide LEM in scene (only light will be visible, like Area Light):

1.Select in Kray GUI Unseen by Rays Casts Light

2.In LW select Unseen:

Your LEM starts be invisible, giving only light.

Here scene:
