I would very much appreciate your advice on how to handle 3+ point perspective in Painter, especially when the vanishing points are way off the canvas. Could you maybe suggest some kind of more automatic ways of quickly building perspective lines to the vanishing points?
When I first saw the perspective grid option in Painter I was in looooove. So happy. I thought it was exactly what I wanted: the supporting help that I can easily hide/show without creating another layer to my image. Turns out I can't find any way to use it. I just don't get it. What I expected was an easy way to select a couple of vanishing points and see the vanishing lines... what I got was a grid of squares in perspectives that for the life of me I can't get an intuitive feel on. I tried to use their lines for help but I got just more confused. Plus most of the time instead of being overlayed on my picture they're standing somewhere outside it so to use them i'd have to zoom out... so for me they're useless.
So then I figured I'd just quickly create my grid. I hate having to worry about an extra layer and not being able to flatten everything constantly but I thought I'd try that. But then I can't find an easy way to to draw straight lines. I'm still in a transition from photoshop habits to Painter so I was kinda hoping for that feature where I just click on a point, hold shift and get a straight line to the second point but I can't find anything like that. Sure, I can use the polygonal/straight line brush... but that's just helpful for the first line. Is there maybe some hidden way of drawing radiating lines? Even if I keep resetting it I have to hit that original point, which is really tough if the vanishing point is way outside the image. I did try hugely increasing the canvas, drawing the perspective and then cropping back but especially for high resolutions that becomes quite a problem too on my system.
It would be so awesome if there was a solution similar to the perspective grid that would be more or less automatic and easy to hide/show whenever needed... I'm asking thinking that somehow Painter has this and it's just eluding me.
