When i move a camera really close up to a 3D layer with a mask, the edge of that mask starts to blur. Is there any way to keep it sharp? I thought with it essentially being vector info I would be able to get up close and it would stay sharp.
The 3D layer is a flat colour, AE solid, with a simple square mask. Camera is a two node camera, depth of field turned off, no movement on the camera, no motion blur on, no frame blending on.
Any pointers would be much appreciated.
A mask on a solid is NOT a vector layer: it's bitmap, and subject to the nastiness you're currently seeing.
On the other hand, if you create a SHAPE layer, it will remain sharp. They're different beasts.
Using masks on solid-color layers for vector-graphics-like motion graphics is an old workflow that has been obsolete since the introduction of shape layers in After Effects CS3. Dave sums up one of the main short-comings.
That explains that one then
cheers guys, really appreciate the help!
