C4DtoA Quad Light Roundness and Softness not responding

[aaronGRU9U]

Hi. I'm using C4DtoA for R21 on a Mac which has apparently disabled the roundness and softness settings for quad lights. Nothing I do in the latest version will have any effect on the lights. I have created new clean scenes and have tried to rule out every possibility outside of it being a bug. Please help.

Works for me.

What is that screenshot? Why is it square when the spread is 1?

[aaronGRU9U]

That's my question. Why does the quad light appear square when the roundness and softness is set to 1?

[Stephen.Blair]

With spread = 1, it shouldn't be a square like that. It looks like spread = 0

[Stephen.Blair]

So I am not looking at the light on some surface, I'm looking at the light itself?

[Stephen.Blair · Accepted solution]

Roundness and softness are not going to change how the light itself looks when you make it visible to the render. It will look like a quad

[aaronGRU9U]

I see. So you can't change how the light looks through the camera - only how the light appears on a surface?

[Stephen.Blair]

That's right. The shape of the visible light doesn't change...I checked an older version too, so I don't think that was ever supported

Ok thanks. Not sure how I got confused or what made me think otherwise. Might have been from using a different renderer way back. Thank you for the help!
