Creating Geometry-Based Lighting in Houdini Solaris

In this tutorial, I'll walk you through the process of converting geometry into captivating light sources using Karma-Solaris in Houdini.
I'll guide you step by step as we bring your 3D scenes to life in a whole new light.

This is exactly what I was looking for!

Wow,nice,thank you! That is super useful!

[@elenatres]

Thanks! very helpful tutorial 🙏

[@madluis9]

thanks man! it was really helpful

[@alexandrkornilov9199]

How do you make a lpe tag on this light source?

[@alexbudulan4663]

How can you make geo light emission work with xpu?

[@wewantmoreparty]

Awesome thanks

[@Mati_Motion]

I did this with instancer and sphere particles, not work. How to do particles emiting light ?

[@midnightround476]

thank you,but how can i create a light LPE tag for this geometry light?

[@HangYuriYangFX]

you need to use rendergeometrysetting to set the tag. and then use LPE to get them in AOVs

[@gregorybennings8718]

I take it Karma doesn't support bloom? I'm assuming this is something you'd add in post-processing/compositing?

[@paun-l8k]

Yes

[@karimoh3154]

nice

[@adriendelmas_]

thanks !

[@mechmedved]

well, how to get LPE tag with output ? )

[@sqworkshop]

why i need make "rendergeometrysettings"??? Emission working without this step

[@ChetalGazdarVFX]

In Solaris, if you want to treat your geometry as a light source with proper light behavior, you need to enable the 'treat as light source' option in the "rendergeometrysettings".if you apply only emission material, it will emit light but won't produce shadows or other light-related effects.
