I created emoji character in blender & it has only head, hands & legs. Can I do auto rig by putting markers to the character without groin marker and will mixamo do auto rig for the character.
no you can't, the Mixamo system is only designed for human models and skipping markers isn't an option
however you can put a normal bone rig then remove the bones you don't need after downloading it... imo its doubtful that this model will rig without changes anyway and a more egg like shape may be needed
Thank you so much ill try.
