You can, and you don’t even have to snapshot the tool. Just rotate to where you want, scale the model up until the res is satisfactory, and grab document. Then go to texture -> Add to spotlight (you might have to select the new texture first. ) Then just do your normal spotlight thing to paint the portion of the texture where you want it.
Note, the ZProject brush wont’ let you paint spotlight colors, you’ll have to have something like the standard or clay brush for it to work.
Edit: I forgot to mention that you might want to set your document background to solid black, that way you won’t have to use the ctl+paint trick to knock out the background if you’re going to be grabbing from near the edge of your model.
As for ZProject – it retains the ZB3.5 (broken) functionality that does not allow you to grab from the canvas as far as I can tell. If you’re keen on using that, you can always duplicate the subtool and move the duplicate behind your model and use zproject.
as an interesting tidbit – you CAN use zproject to pick up canvas detail, but its a huge kludge. duplicate subtools or use any other tool you like, and move it back in Z, and scale it up. Zproject wll pick up any canvas detail that lies between your subtool and your main tool in Z. Looks like the subtool’s bounding box is what ZP is looking for or something.
