I made an excel spread sheet that adjusts the values based on a percentage of the diameter of the ball end mill. It should basically scale this look for and 1/8" or 1/2" ball.

This is a simplified guide to get you on the right path to creating reliefs from colored photos using only free software. Zbrush is way better but this could get you something close much faster. It maynot work with every photo, but it definatly shows promise.

2 TEXTURE SETTINGS THAT I LIKE

A diagram for giving you an idea of depth the tip of a 60° V bit will go when V carving based off of the line width.

VCARVE POST PROCESSOR AND STABLE UGS

​UGS WITH WORKING PHONE PENDANT

TIPS

I made this drawing to help explain the difference of bit size increase/decrease Vs. Step over increase/decrease.

here is the inch post processor I use every time with UGS

The second texture is a combination of the vector texture tool under the draw tab and the texture tool path. for this one, you have to create boundaries manually by offsetting your text and line work. Select those lines then hit the vector texture button. It will create the textures completely within the selected lines. This texture simulates sand blasted sign backgrounds.

First is a texture tool path in a V carved area that was created with a 60 degree V bit and a flat depth of 0.10". that dictates the boundary offset needed.
