Super Knife! Cool New BMesh commit.


Joseph Eagar logs:

Implemented a new "super knife". Activate with k. Holding CTRL will allow extended cutting ala old lines mode. Confirm with enter and escape. You cannot cancel, btw, you can only confirm (and undo later if you want). Hopefully I'll support undo within the tool soon.

  • Supports cutting edges, into faces, etc. You can pretty much do whatever you want. Will snap to vertices too.
  • Note that if you cut into a face, it must be valid topologically when you press enter to confirm.
  • It's pretty and graphical :)
  • You can only cut visible geometry.
  • UVs/vcols are a little buggy still

Now, thou shalt all cease and desist all lack of motivation for
testing! No longer shall users put off testing until "it's cooler"!



  1. I must be the first one to respond on here about this.

    Joe this is so awesome I feel like to cry. I have learned to live without Bmesh thus far.
    But this new commit would bring a whole new level to blender art wise as modeling things
    become a little less labor intensive.

    This is excellent work and I'm sure those that have been following your blog
    will have renewed commitment to you(money wise too :)).
    Thank you kind sir for this...

    I can't believe it blender is finally getting serious for wide pro use. Hurray!

  2. It's always exciting to see updates from Joseph. The B-Mesh system is coming along really well too. Good work Joseph! =)

    Have anyone noticed he sound a bit like Phill Collins? =D

  3. That is very cool. I tried it. It's gonna accelerate so much our modeling. too good.

    Now we need to know where to report bugs and test it. If someone know where to put bugs, please inform us.

    Thank you.

  4. Nice feature, but where is a Bug tracker for Feedback?? (8lender official bugtracker doesn't seems to have any bmesh bug repots, but maybe is just me, since i can't search it) and the previous bugtracker provided by another Blender dev seems offline.

  5. the problem with this is that the bmesh branch is useless at the moment. You can't export to obj. you can't load the blend file to the main blender branch.

    if only the exports and imports were atleast functional many people will be motivated to test this thoroughly.

  6. Joe you da man! I just downloaded a build, checked it out, and that knife tool is something I have been looking forward to. Awesomeness! I've seen a bunch of posts nay saying Bmesh in the past, but I want you know there are a lot of us out here who really appreciate all of your hard work. Bmesh is a very important project for Blender's future IMHO. I am sending you a pay pal donation today. Wish I could buy you a beer, and pat you on the back right now. Thx sooooooo much!

  7. Great tool!!! when will be integrated ?, and can it do subdivide in a edge without affecting the faces? I only see demos whith cutting tools

  8. This looks almost exactly like what I would like to see. I'll have to give it a try myself when 2.6 is available.

    Can it be made to work with lasso or box selection? Being able to just sweep the mouse over specific intersecting edges of planks, boxes or pipes and instantly generate joined vertices would be a real time saver. Modeling intersecting ceiling beams and rafters would be an absolute breeze this way, combining the ease of use of a single knife cut with the instant results of a boolean join.
