Rotating a portion of a mask on the x axis

[Mylenium]

Select the points or the segemnts of the masks, then invoke the transform box by double-clicking. It will only transform your selection, not the entire mask.

Thanks! However, that only let’s me rotate left and right but not forwards and backwards, hence my desire to move along the x axis – how does one do that?

Thanks again!

Scale it. Drag the handles across the selection center and it will flip, smaller amounts act like any inbetween “rotation”.

Thank you very much – I didn’t think about scaling it past that the center point and continuing, which gives the effect of it rotating “top to bottom.” The only challenge with this is, in my instance, I’m trying to do this to an arm holding a sword – it make the arm (the lines of the mask) cross over itself, like a figure eight. THere must be another way…or not…

Be that as it may, please keep the good ideas flowing.

Cheers,

Eric

Masks aren’t really 3D. All those points exist on the same plane and they can’t be taken off of it. Sounds like you’re looking for a quick fix to a couple minutes of roto. Suck it up. Roto is slow-to.

If you ever need a mask to rotate “backwards” (i.e. on the x axis) put the mask on a solid and set that solid layer to 3D. Then make it alpha matte your footage layer by hitting F4 and choosing “Alpha Matte” from the Track Matte selector on your footage layer.

Don’t really understand what you’re saying. Your footage is not moving in z-space, your figure IN the footage is. Not the same. Like the man said, it’s a few minutes of roto, suck it up.
