I Trying out some 3D STL carves and I’m having problem on vertical surfaces being very rough even with finishing runs with an 1/8 inch ball mill and 10% stepover?

If you go under the gear to where you put in the material dimensions, there’s a little dropdown at the top for “model resolution”, change that to something higher. I do mine at the top resolution and it takes longer to calculate the 3d stuff but looks excellent
We’d have to see files and a photo to help diagnose the problem.
If you do this, you’ll need to go back to your model and make some changes, they can be superficial like removing some extra zeros or something, but CC will need to be forced to re-calculate your model.
You can tell if it worked by zooming in close to the 3d parts, especially curves, and if it looks pixellated, it needs to be re-rendered. if it’s nice and smooth, it’s fine.
Just for reference, 10% stepover is what I would consider to be a good “general purpose” quality finish. 5% is where I’d go if I wanted a better finish.
Spacing or stepover on a 3D path is calculated on a plane, so as the contour gets steeper, the actual stepover on part is greater. If possible, set the angle so it’s cutting up & down the steep areas rather than traversing them…
Excellent explanation @Tod1d . I did not know that so thank you.
Thats one reason I do 2 finishing paths, the first across the grain, the second with the grain.
