Reply To: dynamic paint not showing up in render
I am pretty sure the Bake went wrong; look at this:
Blender probably Baked it to a temp file, the Cache field is empty.
If you didn’t close your computer, maybe you can still find the Baked Data in your Tmp Folder (or however that is called on your machine), otherwise you’ll have to re-do things.
And make sure everything works, before closing Blender.
