Blender’s viewport is massively outdated and exceedingly laggy. This has made trying to correct the weights on the ~300k poly model of Red agonisingly painful and take way, way longer than it should be. I still have plans to do a proxy for animating with, but that doesn’t remove the need for the actual model to work. Apparently this will be fixed and updated later this year and from the sounds of the people who are braving it in its current bug-infested state, it will be wonderful.
