Linear Light crashes Rhino

make a Linear Light
turn Raytrace on
every time

any thoughts?

Hi Yelen - these steps don’t make Rhino crash on my system. Could you run the Rhino SystemInfo command and post the results here?

it’s bizzare! I tested on the WIP & no prob!
here’s the system info:

Hello - can you please try disabling this plugins in Options > Plug-ins page and then restart Rhino - any different?


just tried it, still crashes instantly as soon as I turn on the Linear Light
thnx @pascal

Hm… darn, that was my prime suspect… can you also try disabling all the KeyShot plug-ins and restart Rhino? Please make sure on restarting that the Lumion and Keyshot plug-ins are in fact disabled…


still no go
very weird
the scene renders just fine w L Lights in WIP

OK …unlikely it is a plug-in I guess - @nathanletwory - do you have an idea?
Crash on setting a view to Raytraced if a linear light is present (is that correct, @yelenaye?)


yes, that is correct!
(or place Linear Lights, turn them off in the Lights Panel, run Raytraced
, works fine. but if you turn visibility back on while in raytraced mode, ‘crash’ )
thank you!

@yelenaye are you sending in the crash reports for this with the crash reporter dialog that should pop up after a crash?

I don’t see crashes here in 6SR14 release candidate.

I sent 2 back to back and stopped, since consequent crashes would be identical.
thnx @nathanletwory

Did you use the same e-mail address as for your Rhino account? That’ll help me find the correct report from our system.

yes I do :wink:

Thank you :slight_smile:

edit/update: I couldn’t find any crash reports with your e-mail address. I’ll check again after the weekend, in case the crash report processing machine is lazy.

thnx! (the two reports were sent prob 2 to 3 hrs ago)

@nathanletwory do you remember me having the same issue a while ago, I was using Rhino-blend material perhaps it’s the same?

@yelenaye 6SR14 is out. I forgot I had fixed that already for that version. So please update.

no more crashes. thank you !
