there must be something i missed.

in a shader builder i checked 'enable emission' but nothing happens.

what did i miss?

Strange. Your Surface Model VOP doesn't have a fourth green Ce export which is your Color Emission export that needs to be set to a color value in order for your object to emit light.
Version of Houdini?

You can wire in any color (constant, pattern, whatever you want) in to the Ce input of the Compute Lighting VOP to get your object to emit light.

that's strange. i'm using v15.5.480 mac version.

indeed wiring a color to Ce input is working.
thanks,

Better go away from H15.5.480 the shaders (surfacemodel) are seriously broken in that version.
Switch to latest production build or use shaders from H15.0

this was fixed in a recent build.
You dont need to switch version (there where some sorting fixes too on the extrude SOP f.e. so most your modelling SOP networks will fail to cook!)

if you wanna stay in the same version, go inside the surface model shader and plug in the Ce that has a missing connection. (make sure to make it editable)

Once done you can duplicate it into your own hda and reuse it.

cheers.

and you need to fix sss and refraction since they dont work as well,
as i said, to be safe, ignore the 480 build.

Just wondering where you got this information?
There is no mention about sss or refraction in the Journal… ?

own experience
feel free to test it on your own.
