Here is a way to render "dynamic paint" using crowdrender.

you first need to change the temp file path in blender to something more accessible:

after baking all the physics in your project, next to your project .blend file, you should have a cache folder with the following name convention: "blendercache_ProjectFileName".

Synchronize first the project with the rendering nodes in crowdrender, then in each rendering node, find the location of the "svr.blend" file with a size similar to your *.blend project file(found in a subfolder located in the folder defined in crowdrender settings for output files on the corresponding node...), copy the cache folder in this location and rename it "blendcache_svr". now your nodes can render correctly.

If your Master is also a rendering Node, there is an additional task:

go to the temp folder defined in the first lines of this lengthy explanation, and find the sub-folder containing a file "temp.blend" with a size identical to your *.blend project file. Copy/Paste the cache folder there, and rename it "blendercache_temp".

Now you can render correctly.

Not the best I can do in term of explanation, but I hope this will be useful to someone

Thanks James for the response. I will try to follow those suggestions.

Hi Warwick, glad you made it in regardless of how! The password you have is just for the operation of the addon and your cloud account (should you wish to use AWS computers along with your own). The username and password for the forum will be phased out eventually. I just need to find time to get to that!

As for your animation, it seems to me that the physics cache is likely not in the blend file. Also, the timing is critical here for external data like physics caches. Usually they are generated outside of blender, the reason for this is that they get very big, very quickly as you can appreciate. So they are not normally stored in the blend file.

As a result, if the data is not in the blend file, it won't be distributed to the other computers. This is a pain that we're trying to fix. For assets like textures and even other blend files, blender allows you to pack assests into the blend file. But for cache's, its not always practicel due to size. Esp if you want to make changes to the file and then upload them somewhere.

So you have a couple of options here, either;

1. manually transfer the cache files to each computer you want to render

2. reconfigure your project to generate the cache files in a shared location that each computer can access. This may be a network drive or shared folder. Either way, be aware that having the files on a shared location will increase the render time since the cache files will have to be transmitted to each machine at render time. If your network is fast the delay may not be a big impact for you. Also physics caches have one file per frame so you're not going to need to worry about the whole set being transferred at render time.... I hope anyway!

Let me know if this helps! Keen to make sure you get the best from our addon :D
