Excuse me sir, I really don’t want to annoy, but please, can you tell me if there’s some method to select?
I just tried to hit “b” to be honest, but I see this won’t work. Are there any selection tools available?
Excuse me for such stupid question, maybe (again) the solution is just below my nose and I just can’t see it.
Edit: Almost got it, I thought about a workaround: 1st, import the image as reference, 2nd use the reference to draw a nurbs/curve object which will be the selected region, 3rd UVMap it and match the reference to the same texture.
This way I should obtain a nurbs/curve textured object which just uses the portion I’m interested to.
Then, either with render layers and/or with compositing nodes, do whatever you want with the image, after all just render the result to a new image.
The only problem I have is I don’t know how to unwrap a curve to UV.
I tried experimenting with the material, I get vertex coloring, but all the vertices are the same color, there’s no mapping. How can I do?
