Hello,

I'm now trying to complete my lightsaber effects and I need to mask out some areas. The manual explains it easy enough, however, when I apply a mask (any shape) all I get is one dot in the center of the screen.

Am I missing something? (I'm working on a G5, 10.3)

Thanks,
Jon

im not sure what you mean by a dot. A mask comes in a shape ( a circle, squar or triangle. These appear white when applied in alamdb, but when exported, it does its job and removes the effect where it is. FOr lightsabers, use the masks with the feathered edge, for realistic light spill.

As Brettsta said, the masks are all predetermined shapes, and each shape itself is like all of the other effects: It is set in a quad. Therefore, there are only four points to click for ANY of the shapes. Make sure you maintain a consistent click direction for placing each point of the quad.. In other words, clockwise or counter-clockwise.

If that is too tedious, just switch over to AlamDV2 Quad Interface, which makes the quad for you and you edit its shape from there.

Also, a final question, the one always asked: Are you running in 32-bit color? I think I remember some people experiencing problems with masks especially when not in 32-bit color depth.

which is moveabe when modifing the lightsaber quad. (Not acutually a dot, but a tiny square.) I'm assuming the mask shapes have this tiny square in each of their verticies. Well, I only have one of these no matter which shape I select. I can move it around the screen, but it's just one point.

I think I'm running 32-bit. I read the FAQ's and changed my display from "Thousands" of colors to "Millions" before I started using AlamDV. (I'm using an old compaq 17" monitor, but my video card is ATI Radeon 9600 Pro. When I check "About This Mac" there is Display info that says 32-bit depth.)

I found a way around using the mask for this instance, but I'm pretty sure I'll need it when I continue tomorrow.

Thanks,
Jon

Try clicking OFF of the point to see if you can cause others to appear.

Make sure the mask isn't transparent too...

I've tried clicking everywhere, zooming in/out, scaling in/out...nada. I'm not sure about the transparency of the mask. Where is this function? I hope it is as simple as changing a transparency value.

Well, back to lightsaber creation...only 3000 frames left to go.

Thanks,
Jon
