I have a project where I have to animate slices of pizza. I have one object - whole pizza with texture. I want to split it into 8 pieces and each piece must have a separate texture because when I split the polygons with voronoid fracture the new "caps" created from the cuts dont have any texture and UVs. I already retopo each of the 8 slices but I wonder how to transfer each chanel - specular , glossiness , bump and displacement maps from original object to each slice. I have the original ( non retopo ) slices and they have the original texture and UV from the whole pizza.
So my question is how to transfer the 4 chanels from original model to the new 8 object who now have new UVs because of retopology? And all the textures are V-Ray Advanced Matterial because I work with V-Ray
if you have any idea i will be very grateful !
