strange artifacts

Post by basshole »

I don't even know what to call this. Sometimes, when creating shapes, or when I delete points from a shape, I get these "artifacts", these weird, perfectly straight boxes of color, whatever color a given shape is, that stretch horizontally all across the canvas. I get them to go away by moving certain points up or down (conversely, I can make them much larger by moving those same points), but they don't seem to have a "real" origin; that is, I can't figure out why they appear. It's kind of like when you have a hole from points in a shape overlapping in a weird way, but as I said, they're perfectly straight horizontally and vertically. Anyone else experienced this?

This is caused by some type of "corruption" of the shape.

I think it involves accidentally creating "bad" shapes that normally wouldn't exist, when you delete certain points. When creating shapes there are situations with the points selected that won't allow the shape to be created. Or there are points and splines that are crossed or connected in odd ways.

Normally the create shape tool won't allow those shapes to be created. But if you have a shape that already exists and you delete points that CAUSE the bad shape... you can get those wierd artifacts.

The only way to fix this is to delete the shape and recreate it. Nothing else will work. You can't disconnect the points and reconnect because that would destroy the shape anyway. Best to delete the shape and try to redo it. You may find that selecting the same points won't allow the shape to be created depending on how the points are attached.

Ah. So as with most things, it is Basshole's fault. Thanks.

Don't be too hard on yourself.

Just last week I did the same thing. Had to redo the shape. I remember that I was simplifying the mesh and had deleted a bunch of points. During a test animation render the weird "boxes" or artifacts showed up.

It is frustrating but if you are careful it doesn't happen that often.

Question from a newbie

Post by Probie »

Hey all - newbie here saying Hello, How are you? and I recently purchased AS for a few projects I've had floating around that brain of mine...

I'm guessing this is what I'm experiencing? It's odd though, that I can do a render with no artifacts, but as soon as I try to export to swf they appear...

Any ideas?

Yes, those look like the "bad shape" artifacts. You need to check your shapes.

Trying to find the problem shape can sometimes be tricky. Sometimes it is just easier to recreate all the shapes from scratch depending on how interconnected everything is.

First off looking at your file... briefly... you have multiple identical shapes on top of each other in at least one spot causing a bad "stripe". For instance the brown hair on the "FF WM" layer. I found 2 brown hair shapes on top of each other that appear to be unnecessary. Only one is really needed. Also multiple stroke shapes that seem to be unneeded in my opinion. Any of those shapes could be causing the brown stripe coming off of the hair (you can sometimes use the color of the "stripe" and it's "origin" to determine what shape is causing it). The second "top" hair shape on that layer was created in an odd way. It seemed to be missing points causing a hard edge that cuts across the top. I get the feeling some points may have been deleted after the shape was created and then a new shpae was created to fix it. All those extra stroke shapes aren't needed either

Keep things simple is my advice. If you have a stroke around something with a fill, do it in one shape with one file, one stroke. If a shape is "broken" or doesn't seem to be filling everything, don't create new shapes with different points to fix the problem. Fix the points and refill just one shape. If later you need more shapes to create layering than you add extra shapes or layers for that purpose.

I would think seriously about deleting all the shapes and recreating them. It is a simple file that doesn't have a ton of shapes. It won't take as long as you think.
