Short description of error
Dynamics Paint: Paint not working

Exact steps for others to reproduce the error
when one object as a brush and another object as a canvas nothing happens. Then I tried the previous blender version and it worked. Is this a bug? Or is Blender 2.8 a bit different in method so that dynamic paint requires a node shader? I hope this report can make Blender 2.8 much better. Thank you.
