Hello. There is such a problem:
for example, there is a model with UV and texture, but we need to add another object on UV. Or you just need to give more space to some shell. But the texture is already there. How to do this without redoing the texture?
This allows you to adjust the texture to suit the modified UV.
But this is only for older versions of 3Dmax. And there were no updates
Maybe someone knows a similar program, or maybe there is another way to solve such a problem?
I know that a substance-painter can fit a texture to a modified UV. But this only applies to the texture made in the substance-painter, and you need to draw only in the 3D window.
