Mesh Deformer artifacts and issues
-
Hi!
I'm doing some character work, where I sculpt very high poly models (in this case in 3DCoat) and want to really quickly bring them over to C4D to do some quick and dirty pose tests with Deformers. Using Deformers directly on a mesh with millions of polys obviously does not work well, so my plan was to build a low poly cage for use with the Mesh Deformer. However, the Mesh Deformer does not seem suited for this, as it generates a lot of surface artifacts, regardless of the Accuracy setting.
It also seems pretty problematic in other ways, as instead of working as an advanced FFD Deformer which has very smooth deformations, it is sharp and blocky.
Is there any way of mitigating these issues?
Or are there other solutions that could help me achieve what I want with posing/deforming the high poly models?I'm attaching links to a screen shot showing what happens with my character model and also a simplified C4D file which shows how the Mesh Deformer creates very "unsmooth" results.
Thanks in advance!

Hi Andreas,
Thank you very much for the file, very helpful.
There are surely some limitations; I would not deny that. Even if it is possible to have a cage the exact size around it, please consider how much more you can get if the cage is a little bit larger. (Normal Move comes to mind.)
I have not initiated the Deformer, as they produced over 200MB that I would have to store for no real reason. Please Initialize them upon arrival, but at frame zero, for this file! Thank you.I hope that helps a little bit
All the best

Hi Dr Sassi!
Thank you for the reply, much appreciated.It perhaps does not fully solve my specific problem, I might have to go the extra mile and do some quick retopo and exporting a displacement map from my sculpting app to get around the artifacting in my case.
I feel that maybe a rewrite/update of the Mesh Deformer to make it work more like the FFD, with smoother "interpolation" between the low poly and high poly meshes would be very useful, for other cases as well, such as for better/faster simulations of higher poly object.
You know the developers right, perhaps you could give them a friendly nudge...?
Thanks again for trying!
Kind regards

Hi Andreas,
Thanks for the reply.
I will support your request and put it on my list as well, but the chances grow when many people ask for something similar. If you have two minutes:

Perfect, Andreas, thank you very much.
The more input the better. There is certainly a pleasure to provide what is needed and wanted.
My best wishes!
