Dynamic shading does not work when using LB Generate Point Grid

Hello.
Thanks to you all, I am successfully conducting research on dynamic shading.

However, I have a question.
When doing daylight analysis, if I create a grid arbitrarily (using LB Generate Point Grid), dynamic shading does not work.
Below is a comparison example.

What do you all think?

Hi @imj06050215,

This is expected. The reason why it does not work with LB Generate Point Grid is because the grids don’t know which rooms they belong to. If you use what you describe as “Method 2” in your screenshot, the room identifier will be added to the grids when they are created in the component.

It is possible to add the room identifier with a fairly simple custom Python script, but before going down that route I want to know if you are satisfied with “Method 2”, or do you actually need the arbitrary grids?
