Short description of error
Only one Dynamic Paint canvas is cached!! When you have several (e.g. weight and paint) only the results of one is shown (last baked).
In addition, I found DynPaint Baking only Bake 1 frame and stops. when you delete Bake and bake again, it should work.
Follow my description to understand the issue
Exact steps for others to reproduce the error
New BlendFile keep the cube, add DynPaint Brush add Sphere (or what you like), add one Canvas (for now), set to weight, add vertex group as output, (limit frame range for shorter Baking time) add Edge split angle = 0 add Smooth, Factor 0.99, repeat 9, use created Vertex Group animate cube that it brushes the sphere bake DynPaint ---> should replay fine delete bake add a second canvas and Bake the first canvas again (typically it shows "1 frame on disk" first; delete Bake, and Bake again and it shows expected number of frames)--> only the final result will be visible over the whole frame range or no effect.
-----------------following worked only on first glance, but its actually not working when you wane continue working or render---------
work around I found to make it work (probably a hint for you) Delete both canvas caches Bake the second one first (Bake and delete until frames on disk is the expected value) Bake the first canvas --> now it should be as expect
In addition also Cache to Bake also seems affected... but its probably all the same issue otherwise I'll check and report :-)
thx for your work!!!
Based on the default startup or an attached .blend file (as simple as possible).
