Soft Editing


From the weird-but-interesting department: an experimental mesh editing script by Wahooney:

This is the result of about 30 minutes of python and a loose understanding of Jacobson’s Verlet Integrator. A method that allows for soft editing of organic meshes. Not sure if I’ll take this further, some changes might need to be made to Blender to make this easier.

I have a LONG history with Blender - I wrote some of the earliest Blender tutorials, worked for Not a Number and helped run the crowdfunding campaign that open sourced Blender (the first one on the internet!). I founded BlenderNation in 2006 and have been editing it every single day since then ;-) I also run the Blender Artists forum and I'm Head of Community at Sketchfab.


  1. It's looks awesome! Looks like realtime cloth simulation in no gravity state
    i bet it could be useful for RT cloth (soft body) sims in game engine or smth like

  2. Like dsavi said; it reminds me a lot of mesh relaxation in sculptris. Very interesting thing, maybe also when your setting up your scene environment set with cloth and other organic stuff.

  3. Wow very nice. How about using this as a realtime implementation in the game engine. I can imagine some cool effects with this in a game!!

  4. Thank you for sharing the code man ! I took a quick look at it and it's pretty small for such an effect. Cool !

    It's really interesting. I'll take a further look at this next week. It could be really usefull to code a really simple and quick skin deformer !

    Thanks again !

  5. Awesome effect. Maybe the script should called "liquefy", because in fact it liquefys a mesh (like pictures in photoshop).

    very cool

  6. Useful? Absolutely! Experimental modeling is very interesting and gives the artist crazy new tools to push their meshes with. Bless the artist who does not feel bound to re-create realism.

  7. Oh Yeah!! I can really see the use of this. Put on play/record and store all those vertex transformations as animation. Fun psychedelic effects!!

  8. Interesting. It is like applying the fractal-button but then localy. Very handy for making things like trees plants and make variations of instances. Is there a relation with proportional editing (pgup, pgdown)???

  9. This is interesting if you key frame during playback...e.g. realtime vertex keying...that would be great.......
    ....yeah...I'm gonna need you to go ahead and come in on Sunday too.

  10. Thanks for all the positive CnC, guys and gals :D

    I'm looking into the volume preservation stuff, but the day job has to take priority for now. I've already gotten rid of the requirement for a reference mesh, so progress is happening :)

  11. I think is really cool and should be added to the soft selection options plus it would be great to have it as an sculpture option. By the way I have been thinking of a modifier called selector that pases a vertex group to the next modifier based on touch, or interception with other object. That way the "next modifier will only affect that area. What do you think abou it? would it be dificult to do?
