the standard practice in 3D projection mapping in Ae is to increase the shadow map to get better resolution. why is that a problem?
Because if I want to apply camera projection to a footage (full HD or 2K or 4K) the quality drops a lot even if I raise the shadow map resolution.
I stumbled upon this comment on CreativeCow - see if it works for you.
If setting the shadow map rez to 4000 doesn't quite get rid of the blurriness, you can leave it set on "use comp size" and just make your comp size 8k or more. Then crop your comp by putting it into another comp that is your final output size.
it makes sense...
if that does not work:
if you can upload the project please do. if not, can you specify your workflow steps you have taken and your exact setup? this is so I can reconstruct this in my system with similar files and offer a workaround

The highest resolution projection mapping in AE comes when you use Ray-traced rendering. Unfortunately this brings a whole list of other problems to the project. Without complete workflow and comp details it is very difficult to give you recommendations for the most efficient workflow. Personally, for the most of the projects that I do that would benefit from projection mapping I use a series of other more efficient workflows.
