Painting on viewplane

[PsychoPAPPA]

Do you know that the lesson : painting on view plane (introduction to paint effects) makes no sense. Actually you're not making a background like the tutor informs you but a foreground. Like a painted glassplate attached on every camera you look trough. furthermore the switch: painting on view plane has two options: in 3d mode you're painting on the view plane of the camera but NOT on the virtual glassplate. Only when you paint trough the dedicated painteffects window in scene mode you're painting on the 0 to 1 space aka glassplate. The tutor made this mistake also, but is understandable. Maybe you could record this lesson again for other customers so the information is corrected.

Not a complaint just an observation.
Thanxs :yes

Thanks for your observation which is true and false at the same time. There is an attr. surface offset which will control the location of the pfx stroke relative to the camera bkplane. By pushing back the pfx stroke using the offset which we cover later you can get the look you are after.

Right you are painting on the 0-1 space which is the final result that is placed after your stroke is drawn in the pfx window.

Ok ... indeed you can control the depth of the viewplane pfx stroke. And for a galaxy background this works great, but there are issues with this method. I made a test setup with grass in the middle and a starfield on the camera plane. The problem is that you can't control the lights setup which illuminates the grass in the middle. Only at the origin of the world you get good color information of the grass. Look below for a render preview of this setup.

Grass pfx stroke surface offset from +10 to -10, Starfield pfx stroke from +20 to -20. Pic 1: Offset grass/ starfield 0, pic 2: grass -10 starfield -20, pic 3: grass +10 starfield +20.


Maybe you know the solution to get color (light ) information on the negative surface offset settings. Lights setup in that region doesn't work for me.

That's got to do with your shadow information. Set the stroke's Depth Shadow from Surface Depth to Path Dist.

Thanks.. i will try this. Great help here om DT. I'm learning a lot from you guys.

Awesome, thanks Sunder for helping him get this one figured out. There are lots of attrs. on these nodes that are not 100% clear on what they are connected to for a final result.
