Does VrayToon atmosphere effect require lights?

[will_will]

for I test the scene like this with VRayToon atmosphere effect



the VRayToon render element , some alias appeared in shadow area



back light added , alias are gone





so Does VrayToon atmosphere effect require lights?

and last I changed vrayToon line color to red , and all lights deleted , it works well, I got some confused...

( the red line rendered image and VrayToon render element , they are good ）

The gray line is good ,
only black color , in complete darkness , please test it

render result has no problem , but Render Element got alias in total dark area

Yes you are right. Let me investigate a bit further and I will get back to the thread.

Thanks,
And then I tried to delete all lights , edges around object are smooth , edges inside object are noised ...(in render element) , maybe its not depend light..

Hi you could try raising the min subdivs parameter in the image sampler settings.



Start with a value of 2 and if the result is still not good enough, go higher.

It works! 8 min subdivs is fine for my scene, thank you
