Simulate light diffusing materials

@mikkel thank you very much for the quick reply, everything worked out!

Hi @mikkel ,

I didn’t know if a new topic is needed, but I encountered something that doesn’t make sense to me and I wanted to see if anyone has an explanation.

Using the same .xml file in LBT and another calculation software, produces different results.


On the first, the light spots are much more clearly defined. I am using the same radiance paramaters for both calculations. The weird thing is that I get very different DGP values, 63.1% from the first software and 28.6% from LBT.

So I started wondering if I did something wrong with applying the material?

Hi @Hristo,

Are you able to share the model/simulation folder?

Hi @mikkel ,
I am, I just don’t know how exactly. Reading through FAQ atm.
Should I upload the model and definition as I have it. It’s pretty big. Is there a way to compress or am I misunderstanding something?

Hi @Hristo,

If you are able to share the Rhino/Grasshopper file please do so. Just remember that I should be able to recreate the issue, so you have to also upload the .xml file and any other files you have used in the simulation. Otherwise, you should have a folder that looks something like the one below. You can zip this and upload it here.
