Short description of error
Hi, I need to render a normal map sequence using Matcap/Workbench from dynamic paint simulation.
Basicaly the normal map is rendered but only the current frame, not considering the previous frames. I set on "Incremental".
In the Viewport the result is correct.
See attachment (blend file and video)

You have to bake the cache for both particle system and dynamic paint before rendering to get proper results, this applies to all physics objects
It renders the sequence as expected after baking the simulations

This is not a bug, first you need to bake to get the results on render.
