Please move this post to the appropriate forum if need be, but I’m curious as to how you could change the Clip Curve Brush from adding 5 degree angles when you press alt to single degree angles?
This should be posted in the Support >> Questions and Troublshooting >> Other Questions and Troubleshooting forum.
Nevertheless, here is how it works; you hold Ctrl + Shift and click to draw out the curve you can let go of both Ctrl and Shift and rotate the clip line in single degree increments; or hold down Shift to snap to 5 degree increments. The Alt key sets bend points; hitting it once creates a smooth bend and hitting it twice in succession creates a sharp bend. The Spacebar key allows you to move the entire curve.
Thanks buddy!
