Hi. I’m from Japan, and I’m not so good at speaking english.
So, at first, I beg your pardon if I use unsuitable sentences.
my question is below.
In alpha adjastment graph, I want to create a linear curve, but the interporation
is automatically set to spline.
How can I get a linear curve?
…Select a point with your mouse and make an “go out” the graph / “go return” to the graph without release the mouse!
As like curve line become straight line or inverse 
Welcome aboard 
Have happy Zbrushing!
