So if I keep the value of the eraser at "1" then what do I need to change to add the voxels? It seems that no matter what value I put for drawing/erasing, I click and get a black box drawn on the screen. It seems that I am not combining button-clicks or values for the eraser and adding correctly.

Thank you

Hi Alexander,
If you are editing FS recons, then you should keep the eraser value set to
"1" so that the edits can be detected by recon-all.

I set the eraser value to "0", but when I draw, the voxel still shows up as a black box instead of grey. Am I not setting the right values or am I just in the wrong viewing mode?
