Sure Achim, As a matter of fact, upon trying out the mask more, I have found that it does work (for me at least). I can't reproduce the weird GL state that things went into for me when plugging in the video input earlier today.... though I did manage to evoke at least one Quartz Composer internal error just from opening the composition, which doesn't give me a warm feeling. (It's possible that these two weird side effects I've noted could be unrelated to the hit test patch; I'm not on a clean install right now.)
Here's an example qtz without use of the image mask. The mask input is working for me when I feed it some simple png's with black/white (or even video), but there are a couple of things about sizing when using the mask input that are throwing me off at the moment. -George Toledo On Sun, May 16, 2010 at 3:01 PM, Achim Breidenbach <[email protected]> wrote: > Hi George, > > do you have a sample composition where we can have a look at? > > Anyways, if you just want to have a simple hit test on an image mask, you > can also use the Image Pixel patch. > > best, > > Achim Breidenbach > Boinx Software > > On 16.05.2010, at 16:20, George Toledo wrote: > > Unfortunately, private patches are considered unsupported, so I wouldn't > expect to get an answer, unless another user has it figured out. > > I will say that in SL, if I place an image in the mask, I don't get an > error like that, but rather, QC goes into a state of insanity. > > If I have an output on the Hit Test connected to an Image With String, and > then a Billboard, to test hits, and then connect an image to mask, the > actual Billboard connected to the image with string blanks out.
