Adam -- 2.0.0.7 is correct.  I think Jeff got a little ahead of himself.  :)

Hi Jeff. I just reinstalled diva - version 2.1.1.1, but the grasshopper version is still being shown as 2.0.0.7, not 2.0.0.8.  Is 2.0.0.8 included as the DIVA.ForGrasshopper.gha in the C:\DIVA folder? I copied this into my gh components folder, but I'm still seeing 2.0.0.7 as the component version, not sure why..

Hi Adam,

This should have been corrected. If you right click on a component you will see the version- if it is not 2.0.0.8 then you should install the latest version. Let me know if that does not resolve the issue.

Thanks Jeff. I would like to use the GenericTranslucentPanel_20 material, but this material is not shown in the gh material component even though it is in the material.rad file and accessible in the rhino diva menu. Not sure why it is that I can't get to it in gh. I see in the material.rad file that "The model requires the following two files have been added to a directory included in your RAYPATH variable (c:\daysim\lib or C:\Radiance\lib): rang.cal & Translucent20.dat" I'm not sure if this could be the problem because I only see "rang" in my Daysim\lib and I don't see "Translucent20" in either folder.. Any thoughts on this? I found that someone else had similar problem not seeing the translucent material in the gh menu.. here.. Not sure if they resolved it..

thanks

Adam

Adam- instructions for creating a custom radiance material for the grasshopper component are here.

Hello. Is it possible to use a translucent glass material in a daylight analysis using Grasshopper? The specific problem I have is that I would like to model a translucent skylight and use grasshopper/diva to test angle variations of shading fins above this skylight on interior illumination levels. As there is no translucent material in the gh diva material component, is it possible to assign a custom material in rhino and then include it in the model which is analyzed when the gh daylight analysis is run? or another way to do it?

thanks

Adam

The component is crudely meshing a nurb surface. Try meshing the curved surface to the desired resolution and then pass the mesh to the component.

Hi,

I have a problem with the geometry. It comes as a curved wall to the input on the Diva material component and exits as a simplified straight wall after this component.

Any advise or help?

Cheers!
