Ladybug Tools for Sverchok and Blender

  • I would really like Ladybug for Blender 4 and preferable parts of Honeybee. At least the geometric parts.

  • As im sure the BlenderBim has more focus than these analytical tools, perhaps the VI-Suite can be an alternativ for temporary use until we see Ladybug and Honeybee comes around?
    The VI-Suite tools can be shown here:
    https://blogs.brighton.ac.uk/visuite/images/

    However, VI-Suite uses blender file format, so any parametric studies with IFC nodes will not work. You need to export IFC with BlenderBim, save the file to Blender file format and change all items which contain "/" to "-" or any other character as VI-Suite for time being do not support "/".

  • An alternative is to use the donate button and set up recurring payment and indicate that development of this module should be prioritized. I have done this, but we need a critical mass to help prioritize development.

  • For users of ladybug tools, is there a significant advantage in doing these analysis on 3D solids as opposed to analyzing rasters? I think Whitebox Tools and some GIS-oriented programs can do some of these metrics.

    For those unaware of Ladybug tools,

    Please, update Ladybug tools, Blender 4.0 and so on. It not works

    We are in times where Sustainability is a "must" in everything. Ladybug tools "must" be in any OpenSource workflow.

  • BlenderBim and Ladybug were the reasons I started to use Blender two years ago. Sure, I can use Ladybug in grashopper but it is much harder to integrate into an efficiant workflow.

  • To revive this thread and save all the effort that was put implementing ladybug-blender, I've updated the https://github.com/ladybug-tools/ladybug-blender to support the latest version of sverchok. No other changes added, only api update and it seems to work (tested on Blender 3.6.11, on Blender 4.0+ sverchok is throwing lots of errors not sure if it's supported completely by sverchok).

    Latest build:

  • Would this build of ladybug tool yield same issue as VI-Suite where the "/" sign in the IFC scheme will make non radiant material? Also, are you the main programmer for ladybug tool now for BB?

    No idea, it works the same way as before sverchok made changes to API.

    Also, are you the main programmer for ladybug tool now for BB?

    I work on BlenderBIM, just wanted to help out with ladybug tools as the changes wasn't really related to the ladybug internals but just how it was integrated with sverchok.

  • @Andrej730 Thank you, I was hoping the LB add-on would come back to live soon. I've tried to get it working but I am getting this message:

    Any idea what is going on?

    What version of sverchok and Blender?

  • Blender 3.6.11
    Sverchok 1.2.0

  • Blender Windows portable (.zip), not the installer

  • Yes! Thanks a lot :)

  • Hi everyone,
    I tried to replicate @pstrokap 's success, I got some results (compass, sun paths etc.) but I ran into an error (red box) on "LB Direct Sun Hours". What am I doing wrong? Thanks for your help!

  • @topologic got the same setup as you and it seems to work. Here's .blend and .epw (rename extension to just .epw after saving) for a reference.
    I use ladybug-blender-240515, latest sverchok from https://github.com/nortikin/sverchok and Blender 3.6.5.

    Perhaps check system console (Window - Toggle Systen Console) - maybe there are some errors?

  • Thanks. The issue was that I am using Blender 4.1. Some of the LB nodes are not working in 4.1

    I believe some of the sverchok features are not working on Blender 4.0+ as well, so currently it's better just to stick to Blender 3.6 using sverchok.

  • This tool is needed...

  • The Sverchok download page was updated with the current working versions for different OS.

    Hello everyone,
    im new to the community. first of all thank u very much for the incredible work so far, making so much possible and accessible for all (Sverchok, IFC Sverchok, BlenderBIM)!. im now very interested in getting my hands on Ladybug, but having some trouble finding the node "LB Out". I see it in the demovideo and in the most of the shared screenshots, but im just not able to find it in my system. Im using the recommended: "ladybug-blender-240515, latest sverchok from https://github.com/nortikin/sverchok and Blender 3.6.5."
    tried also sverchok 1.2 and sverchok extra without the expected success. in some older posts i see a "LB to sverchok node", which i wasnt able to find neither. is there something im missing? would be very thankfull for any hints or ideas.

  • @nicomora
    it appears you're trying to find a node through F3 Operator search:

    When there is a special search for nodes that can be added available in shift-a menu:

    Search itself:

    solved by this. thanks a lot!

  • Though I think it's still a bug since LB Out is indeed not present in any Ladybug nodes subcategories (should be in Ladybug -> Viz). Seems like a bug in sverchok itself, documented it on github - https://github.com/ladybug-tools/ladybug-blender/issues/47
