Exist the possibility of make a normal mapping just switching morph target with the original low poly model, and then, use the Zmapper for this.
But how we can do the same with the painting?. We can import the low poly, but for extract the polypainting we need go up to the highest level, and, of course, the original low poly model deforms again. How we can do this?.
Simply store a morph target before dividing the low poly model. When you return to level 1, switch to the stored morph target. No problem at all.
How extract the high resolution polypainting over the low poly model without go to the highest level?
Yes, store morph target first BUT also, when you are subdividing, turn off Smooth UVs (Suv) so it doesn’t smooth out the model when you subdivide.
