Light pass through glass

General
1

Hello all,

I have a building which has glass windows. The problem i am facing is that the light does not pass through the glass material. The material act like an opaque material. I have tried many combinations of glass material but none of them let the light pass through though everywhere else it happens.

Pls let me know how I can have a glass material which act like a normal glass letting the light pass thru.

thanks

Hi @Harsh_Sharma, two initial questions:

  1. Are you rendering this model in CesiumJS?
  2. What is the format of the model? Is it a glTF? If so, how are the glass windows defined? I ask because there is a KHR_materials_transmission extension which is not yet supported in CesiumJS.

Hi,

I am rendering in cesiumjs. I have tried the glass material both with transmission and without. Either case, the sunlight does not pass through…

Are there any plans to support khr material transmission in cesiumjs?

Thanks
