You can make models made from 3D (polygonal) training data work in most styles (and better with "3D" tagged in generation) by just tagging the applicable data "3D", otherwise it learns 3D as an inherient part of the character (and not really all that well). Works in at least SDXL, PDXL, ILXL, and (with lower dim/alpha) Anima. Its not widely known (because most people don't say much about their training process), but its something that really helps.
