luminous polys without emitting light

[_mats_]

Hi -

I was wondering if there is a way to have polygons that are "luminous" but do not emit light?

for instance if I have some ceiling spotlights and I want them to be pure white, but not be computed as a lumi poly by Kray, (since I will be using an actual spotlight or point light under it)

any ideas?

thanks

... drive diffuse above 100%

(not sure if it might possibly mess with other aspects of your scene tho - someone else might know if it does)

Top row are luminous polys@500%
Bottom row are diffuse polys@500%

excellent tip

Thanks ! glad to see there is way to do this

loving Kray here

no probs ... there are a lot of things in LW that go above 100% .... and quite a few that go below 0 for that matter. Always worth knowing.

You can also put them at 99% and set luminosty threeshold at 100%, so all lumipolys under 100% will be computed in indirect mode. It's fast and this gives you a "halo" around them since they emit light in irradiance phase, but nothing more since they wont fire FG rays.

Great tip Pavlov many thanks

Yes, excellent tip Pavlov.

Both tips work great, I suppose for slightly different circumstances.

Thanks to you both !
