I have a complex model and I have unwrapped it using texture atlas. Now I want to place uv islands in two uv sets (UDIM - I’m planning to use two 4096x4096 texture maps on this model)
A single object of the model cannot have uvs on both uv sets (please look at the example). This model have hundred of objects. So placing uv islands manually on both UV sets is not easy. Does anyone know how to place uv islands easily while maintaining the uv scale according to the objects? If you have other ideas about this please let me know. Thank you.
Here is my model.
Here is the current uv map
