Can freehand masks do this?

Hi,

I've watched the tutorial about drawing masks around objects so that emitter effects seem to be behind them; eg, a muzzle flash from a gun that's pointing away from the viewer. As I understand it, you apply the muzzle flash emitter first, then draw a mask around the gun and hand, and this mask obscures the muzzle flash the same as the gun itself would if it were real footage of a gun going off.

I see that the freehand mask drawing tool is accessible in EffectsLab Pro, but I can't seem to get it to do this.

So, my question is, can you in fact do this process in EffectsLab? Or is it only available in CompositeLab?

Thanks.

Yes, the masking in EffectsLab is entirely capable of that. And it seems like you understand the process from your description. Where exactly are you running into problems?

Not so much a case of understanding the process, as an educated guess, Axeman. After Effects has that tool, but I didn't really expect a relatively inexpensive app like EffectsLab to have that capability, to tell the truth!

Since I posted that, I've read the tutorial re adding a flames to a window, and so now I know it can be done and how to do it.

Almost. Only problem I'm still having is closing a freehand mask off. I draw a few points by clicking, but when I want to close the shape, I can't. Tried dragging the last node across but it brings the line with it.

Any clues are apreciated but maybe I'll just plod away for a while before posting a query every step of the way.

Thanks.

Yeah, sometimes I have that problem. But it can be fixed fairly easily.

Mask out the parts of the fire you want to show, then turn on "Invert Mask". It's hard for my limited mental capacity to explain clearly, but I hope you understand me. If not, I'll try to upload a picture.

To close the mask, when you get to the last point, just add an additional point pretty much anywhere, then drag it to the origin. Don;t try to draw a point on the origin, just add another point alongside it or whatever, that you can drag to close the circuit without moving the position of the last point you need.

Okay, thanks, Axeman.

Cheers.

Think I've got it now, TV. Thanks.

Cheers.
