masking

Hi

I’m a complete beginner, so please excuse how basic this question is. How to a center a mask over a form? I’ve set myself a project of sculpting an eye, when I try to paint a circular mask on my sphere I’d like it to remain a perfect circle but I can’t find a way to snap the mask to an axis. The mask ends up slightly off axis and so is stretched across the form.

Kind regards

Jon

I’m noob.

I really want to know that too. (couldn’t find how yet)

but I usually eyeball to find centre of circle.

  1. If the sphhere is not too high polygontry or dynamesh

Ctrl +F to bring up grid of an object -> turn on X,Z symmetry to aim its centre(where 4 red points meet)

  1. use local sym or radial symmetry…

sometimes zmodeler’s much more convenient for making something geometric (sphere,cube,cylinder stuff)

Thanks for the reply, I’ll try out your suggestion. I have another issue I’ve encountered, when I mask a circle it reproduces the mask on the other side of my polysphere, it’s not the symmetry function I tried switching this on and off, any idea what’s causing it?

Regarding your first question…

Regarding your second question…

While holding down Ctrl, turn on “BackfaceMask” in “Brush > Auto Masking”. This, however, will only work on the following stroke types…

For the other stroke types, you will have to hide the back.

Hi

Thanks for your suggestions, I had found the centre and square functions and they definitely helped but they still don’t centre the mask on the sphere. So far, the best solution I’ve found is using these functions and making a best guess about where the centre is.

Regarding my second issue, I realised, my polyshere is slightly transparent (don’t know how it happened) so it was projecting the mask through the form. I haven’t found where to adjust this property but I’ll just start again for now and try and locate it another time.
