3D Quad Distort Artifacts
-
Hey all,
So, I'm getting some weird artifacts when using the 3d quad distort projector to map onto a setpiece. No idea why they are happening. I've attached a photo, you can see these odd black spots on the face. I'm not at the projection computer so I can't post a photo of the actual patch, but I mocked it up quickly here at home and photo is attached. The real one just has 3 of those setups (one for the face, one for each of the stripes.)Does the 3d quad distort actor not like being stacked? I seem to only have this problem in scenes where I have multiple quads layered on top of each other.Thanks in advance! -
Why are you adding an alpha if the projector is set to additive?
-
Whoops. Missed that in my mockup. They're set to transparent in the actual setup. I'll take a screen grab when I get to the theater tonight.
-
also if you could, a shot of what the Mask image (from picture player looks like). Just trying to get a sense of what you are trying to accomplish.

Thanks for your help so far!
Attached are:- a pic of my stripes patch- a pic of the sphinx head patch (couldn't get them all in the same screen grab, but its all the same scene in Izzy)- my sphinx mask. -
I guess I don't really get what you are doing here.. Is each a section of the sphinx, and you are filling with a color?
In any-case, I don't see anything that should leave black artifacts, however; I would try switching the 3d quad distort projectors to different layers. -
Dear SSiezas,
The most helpful thing, if you want me to try to recreate this and see what's going on is to 1) create a sample patch that uses your images, 2) zip all of the elements (.izz file, pictures) into an archive and 3) send me the the whole package. Then I can open the patch and see what's happening.You can send the data to mark [atta] troikatronix [dotta] comBest Wishes,Mark -
Well the problem somehow fixed itself at final dress. No idea why...
The only variable I can relate to the problem is that I was still fiddling with the quad distort actors at previous rehearsals. Final dress was the first time I opened the show file and didn't change any settings in those scenes.All fixed though!Thanks for the help. -
I find that sometimes when working with quad disort that I have to click off the scene and go back into it. Perhaps this is what happened?
(However until recently I was working with a really old machine, so that could have been why)
