Hi Shohei, thank you very much for your reply!
to be more specific, when I said “I created an postprocessing outline on my multi-mesh characters” I meant that I followed this tutorial and enable it in C++ on each individual mesh, but the material itself it’s really just a copy paste of the uasset files.
also, when I said “everything is done in C++”, I meant that I prefer C++ over blueprints, unless required or I’m unaware of any other way besides blueprints.
other than the steps described in the above tutorial, I’m not aware of any other setting depth related. My understanding of rendering is basic, in my case I just naïvely assumed that all things being equal, the outcome should be simple and straightforward. I understand your question about setting the depth of the mesh, but if the answer is not In the tutorial, which steps I followed because they were mentioned, not because I actually understand them, then I’m not aware of any other way how to actually accomplish this correctly.
Thanks again for your reply!
