I just wonder - is there such thing? It would save a lot of time, because we could use smart uv projection more often, instead of time-consuming and boring manual uv-mapping. (I’ve just spend about five hours for uv-mapping).
For example, i have several different uv islands. These uv islands have very different size. Some islands are huge, others are tiny. If i use automatic packing (Ctrl+A, Ctrl+P) with fixed margin for every uv island (for example 0.40) i recieve a non-optimized texture with lots of blank space, where small uv islands looks like holes in cheese.
So it would be nice if there happen to be some algorithm which can set up relative margin for smaller uv islands - the smaller the island, the smaller its margin. With this algoritm we could have properly packed textures, even after automatic uv mapping.
I mean, we could deliver another one devastating strike to destroy manual uv mapping forever
