   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.

   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.

   Greets from Berlin.

   @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:

    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

    Is there a way to change colour gradient with nodes from yellow and blue to another ones? And also change gradient data type from sum year hours to something else?

    Hi @bicukow, I think you might find answers to those questions on the ladybug forum: https://discourse.ladybug.tools/
