Stroke wierdness
I’m applying the Stroke effect (not 3D Stroke) to a simple, rectangular mask. For some reason, different sides of the mask seem to have a different thickness.
The effect has a brush stroke of “4.0”. However, while the right and bottom of the rectangle seem to have that thickness, the top and left sides are thinner.
The image is scaled down, but that shouldn’t matter, as all four sides should be affected equally by that scaling.
I get this same problem when I use Trapcode’s 3D Stroke as well.
Anyone have a clue as to why this is happening?

If the combination of your layer’s scale and position means that the edges of the mask are “between” pixels, and you’re not at full res, you might see that problem.
Are you at full res, with the layer at best quality?

Yep. Comp is at Full Res, Layer at full quality. And I had tried changing the image position since I thought it might be “between” pixels. Had the same result.
Perhaps it’s b/c of the scaling, but I can’t understand why that would only affect certain sides and not others.

Hmph.
Can you send the project to ads (at) reidroberts (dot) com?

Rectangular pixel issue?

Actually, I think I figured it out. It seems I had to adjust the mask itself on the layer.
The layer was masked, with the top and left sides of the mask being at the edge of the original layer, while the bottom and right sides were in from the edges (thus cropping the image on the right and bottom).
It seems the Stroke effect only goes so far as the edge of the layer. And since the Stroke effect acts on the center of the mask edge, half the Stroke is on one side of the mask edge, half on the other side. So for the left and top, which were at the edge of the layer, only the “interior” half of the Stroke effect was showing. Whereas for the right and bottom, both sides were showing.
The solution was to pull the mask in on the top and left, cropping a bit of the layer. Thus, the Stroke was visible on both sides of the mask edge.
Essentially, the Stroke effect is bounded by the dimensions of the original image. If you pull the mask past the dimensions of the layer, the Stroke disappears altogether.
BTW, thanks for your offer to take a look at the actual project files. It is greatly appreciated!
