(fixed,fixed) [HOU-1959][HOU-1977] Light instancing broken

V-Ray V-Ray for Houdini Issues
1

Trying to instance lights does not seem to work anymore with yesterday’s build. example attached. while testing this, it would sometimes suddenly work when changing the geo in the instancer but I can’t recreate this behaviour.Geo instancing seems fine though.

Cheers,

Hi,

I think you are having the same issue that I reported here: (done) [HOU-1958] Sphere lights not working in latest build - Issues - Chaos Forum

Don’t use this latest builds, the lights seems to be broken.

Best,
David.

Ha, seems so. Are you saying that the build from two days ago works fine or should we go back further? We just updated from the build from may 13th which did work fine except for some issues with the image save path. I hope these issues get resolved soon as I would really like to have some of the improvements that went in in the last couple of weeks.

HI @ronald_a , the build from 2 days ago is a no go too. We tried the nightlie from the 8th (**V-Ray:**4.30.03-2020.06.03) and the 3rd (**V-Ray:**4.30.03-2020.06.08) and both had issues, so in the meanwhile we rolled back to the version we were using before, 11th of May. But I’m sure there are other builds between thhe 111th of May and 3rd of June that work too, but we don’t have time to go and test them all. Until it’s fixed we’ll keep using that older one.

Best,
David.

Hello guys, yes light instancer is broken since 31th of May.

6

Does that mean this is also broken in the relatively new SP1 release for Houdini?

Thanks

Hey @thomaskc ,

no, the light instancer is working in the official release. We held on to a few changes that made it to the nightlies right after the release. We had checked them separately but apparently something went wrong once everything came together. As always, we’ll message once we figure it out and things are stable.

Best regards!

All good! thanks for confirming!

@david.anastacio thanks for the info. we‘ll wait for a fix then and revert to a version before 31st may then.

Light instancing is now fixed.

I just had a quick look, but it seems the problem is still there (tested with my example scene). Or will this be in tomorrow?

12

Sorry, I’ve tested Light Instancer with RectLight and it were working, but instancing V-RayOmni isn’t.

13

Hi @chakarov ,

Are all the light problems fixed? Or does this one still persist?

Best,
David.

Hi @david.anastacio , the issue is in “code review”, so if everything is OK should be in nightly builds soon.

Lights instancing should be working in tomorrow nightly build.
