I am trying to figure out how to get my lightbulb coil to emit light via the Luminance channel. I have tried a few tutorials without any luck. I don’t know if its due to r16 new material system.

Plus I can not figure out how to get the luminance color to show through the glass material. It shows up black.

Thoughts.

Hi Creative Raul.

This was awkward (... something in the app is not OK!). The Ambient Occlusion option in the Render-Setting disabled this. Switch this off and it works.

(As I don’t use AO - I never encountered it. AO is an artificial and geometry based only simulation. Nothing that has anything to do with real light. I think that GI doubles the information were it is correct, so… However, many people love it, so ignore my comment ;o))

However, it should not disable that Luminance information is invisible. This needs to be cleared by the Support, which would be nice if you could send your scene files from above as it is to them, Thanks!

What I do not understand is the use of the AO shader in the Luminance channel for the Lightbulb coil. Perhaps I miss something.

What I do changed was the Light bulb glass body. The one I found in the scene was more a full glass body. I copied the object twice, changed the Normal on one, then made a normal move to make it smaller. Both selected, I used the “Connect and Delete”—which comes closer to the “normal” bulb, if that was the target at all.

I placed a Buffer to the coil to have a Glow effect on it. I saw that in your Render Preference. But the Object Glow works not for objects behind others, e.g., glass.

Note that I reduced the resolution of the coil by setting the interpolation setting differently.

The image is based on Global Illumination. Note that I have switched a lot of objects off. Your results might vary. It is low quality/preview!

All the best

Dr. Sassi,

In your reply it sounded like you attached a file. I do not see any files by you on the post. I’m having a hard time understanding what you did exactly.

The file is now part of the post. Sorry about that, CreativeRaul. I got the message that the zip file was the wrong MIME file. So I had to use an alternative.

I hope it works for you.

Dr. Sassi,

Thank you for the help. That is exactly the look I was trying to achieve. I have less yellow in the corn of the coil but I’ll work on figuring out why.

You’re welcome, CreativeRaul.

It should be the same, but perhaps dial in more intensity. See image.
Sometimes it is advisable to render out passes, so you can adjust things better.

Like Colorway from The Foundry, which is roughly a Multi-pass adjustment/comp. tool that I have had suggested in 2011 in a similar form to them.

All the best

Sassi
