@francesca pracanica Almost all of the functionality from this addon is now in Blender by default. You can now just mask off a part and use the "Mask Slice" or "Mask Extract" operators in the header menu "Mask".

@Julien Kaspar I didn't know, thank you very much.

For your work experience, I know the question is subjective and depends on many factors. But in general have you found problems using mask slice, or mask slice and fill hole in a mesh with many polygons, 1 million or more?. blender might crash and it is better to use other methods to deal with what you have to do?. I just want to know your opinion

@francesca pracanica Yes these can be quite slow to use. On very high resolution meshes I can recommend to use the "Line Project" and Fairing options in the "Face Set Edit" tool and afterwards remesh.

@Julien Kaspar Ok understand, it always depends on what you have to do because the options, even of the same brushes or tools are many.

My questions are in reference to your video, where you remove a part that comes out, like the leg. You mask it and you could do "mask slice", or "mask slice and fill hole". Or invert the mask and use the brush "line project". Or use the draw face set and then edit face set where there's a "fair position" option and others.

Thanks Julien, I try to learn from these questions.
