Hello,
I was just wondering if someone could point me in the direction of which LOP node contains the Karma render property for the camera shutter speed as shown in the documentation in the image I attached. It says it is a Karma Render Property, but I don't see that anywhere on the Karma Render Settings. I do not see it on the Render Settings LOP either. The camera LOP has the shutter open and close, but that is different than the shutter speed. Can someone please help me find this?
Where to find the camera shutter speed?

Hmmm, that's what I was afraid of. If it was removed, it should be taken off the Karma documentation. SideFX is usually so good at having good documentation.
In light of not having the ability to control shutter speed, does anyone know how to approximate the 180 degree shutter rule for camera motion blur? Is it just having a shutter offset of 0.5?

damon_c_johnWhat do you mean not being able to control it?

It's the duration between shutter open ad shutter close
So -0.25 to 0.25 is equivalent to shutter speed 0.5 and shutter offset 0
-0.5 and 0 is equivalenr to 0.5 and -1
0 and 0.5 is equivalent to 0.5 and 1, etc.

Ah, okay. I think I just had a misunderstanding then. I came from recently from renderman where they had the shutter open time and shutter close time, but I think it just didn't register in my head that an open time of 0.5 was the same as -0.25 -> 0.25. But it makes total sense. Thanks for the response!
