hey all so I tried many times to export my own model to mixamo but every time I export it to mixamo than I apply some animation on the rigged body in mixamo , After that I download the animation and import it to blender , but Every time I do this , the character will be full white mesh , no texture on it , I tried to pack and unpack resources but It did not work , I m pretty sure something is wrong or I missed something ? thanks in advance

the one on the left is the original texture with paint tab , right side is the mixamo one
