Remove some kind of stroke?

[torritorri]

I recently updated anime studio pro 9 to 9.2.
Then when i opened a project, i noticed that when i render it out, it creates something that looks like strokes, on the bushes.
A yellow line along the edge. I have turned off the strokes for those layers, and tried to get rid of it by adding strokes and then removing it.
But it doesnt work :/
If i turn up the stroke width, the yellow line is still there, but at the edge of the stroke.
And you can also see a tiny yellow line along the house wall near the bushes.
Why is this happening, and how do i fix it? pleeease help!

are you using masks?

Similar Here Too, I am too new to know that it may bee a bug, but when I imported a obj plane (to use as the ground), the edges of it done the same thing. I tried everything to cure it, could not. I resorted to making the object again, but bent down the edges that are in the scene in order to hide them. Of course that makes more lag, but what I had to do.

No, im not using masks.

hmm .. I got a similar effect with a mask "misbehaving"!

I've just run a try-out on antialiasing. it looks as though, with antialiasing on, at the boundary between between two curves, AS generates pixels of varying colour density (might be a blend of the colours of the overlapping shapes). In the experiment I did, I found a "dead straight" line had a one pixel "boundary"; a curved line had about 2 pixels of colour graduation.

so maybe try again with antialiasing off and see if you get the artefact?

I have found the solution to the problem!
When i set the auto shading radius down to 0, on those layers with yellow lines, all the yellow lines disappeared
But here's another problem - How do i fix this, so that auto shading creates shadows instead of ugly yellow lines?
