<p>I'm looking to produce different visualizations where I change the color and transmissivity of my window panes (see attached two images with the same color and different transmissivity).</p>
<p>Changing color is easy with a custom material (I'm using Trans in the radiance library), but when I change transmissivity I only see the decrease in incoming light across the room, but the "brightness" of the window doesn't change. In theory the window should appear darker as less light is transmitted…</p>

<p>Hello!</p>

<p>Hi guys,</p>
<p>I have a problem, which I hope you can assist with. I run DIVA version 4.1.0.12 in Rhino 5, and have been using the program for a few years with success. However, now I have a problem where I experience unrealistic results when running simulations for different models - both simple and complex ones. </p>

However, now I have a problem where I experience unrealistic results when running simulations for different models - both simple and complex ones. </p>
<p>As you can see in the picture Test box when running a very simple model, the DF is 100pct in all of my calculation nodes. Notice, all of my layers are turned on and there is a roof when running the simulation.</p>
<p>Pic. 2 show a more detailed model with a clipping plane inserted afterwards, where the result is also 100pct. in all of my nodes.</p>
<p>I have also tried changing the materials, uninstalling, reinstalling, an older version of DIVA.</p>
<p>I have also tried sending the models to my colleagues, who successfully can run the model showing realistic results. Based on this I assume it is a software issue...</p>
<p>The last picture is from the .rad file created by DIVA when running the simulation - so something goes wrong on my computer - but what? I hope you guys can help me...</p> diva daylighttag:www.grasshopper3d.com,2018-07-19:2985220:Topic:19217342018-07-19T20:42:11.254ZJeff Niemaszhttps://www.grasshopper3d.com/profile/JeffNiemasz

<p>I am a PhD student and I am using diva/grasshopper for doing daylight simulation.</p>
<p>I want to ask about: how could I customize a kinetic shades and define it in Diva daylight analysis as a shading device? notice that I have already build the kinetic unit on grasshopper.</p>

<p>Hi everyone, I'm trying to do a simple simulation of a house (regular ortogonal geometry, nothing fancy) and it just won't run it. I opens energyplus prompt but it keep appearing this error: 1. Solution exception:It was not possible to locate the file 'c:\(...)\diva\testeout.err'.</p>
<p>The same geometry and setup was working on the previous versions, I've uninstalled DIVA already and reinstalled and even put em exception on by antivirus... any ideias??? Thanks!</p>
