Paint Fx toon lines Issue 2

Here' comes an issue with flickering thin lines. Again I render the pfx lines on top of a use BG shader. Notice how the brightness change at the 3 vertical lines at the left.
First I thought of clipping plane problem because the scene scale is pretty big- So I turned off optimized clipping plane and uses optimized min/max settings, but it didn't work.

Any ideas/tips???

thank you in advance

I doublechecked my clipping approach. I offsetted the Toon-Outline and I rendered only a very narrow Min/Max camera clipping value. No change.
There must be another reason why my Outlines are flickering from frame to frame.

ok... the format of your materials is a pain in the ass to look at. might help to merge the images onto one long image and maybe crop and highlight the problem geometry.

if your lines are too thin for AA to consistently sample, you will get flickering. could also be a depth sorting issue if you have two lines who are running in nearly the same path.

Note that with pfx lines the normal antialiasing settings of the render do not apply. Turn on oversample and oversample post filter in the render global(under pfx render options) to improve the antialiasing... in particular with regards to integration with the depth buffer. Another option is to convert pfx to poly and make the normal aa-min/max levels high.
