Retopo Shader going dark

Hey,

I've noticed that when I rotate around my mesh during retop it sometimes flashes the shader to this solid black version and breaks the see though alpha effect. Zooming in/out makes no difference happens at both distances from the mesh. When i rotate past a certain point the shader goes to black. It triggers on and off as i rotate back and forth past that point.

On closer inspection it looks like the retop mesh is having a sorting issue. It is still visible in the upper right of the second image in areas where the transparent mesh isn't covering it.


also getting "The attachments upload directory is not writable. Your attachment or avatar cannot be saved." this error when trying to attach an image.

SOLVED!

my base retop object was not fully opaque and thus seemed to be causing sorting issues!

Thanks
