Light Point of view

Hey everyone,

I am trying to calculate transmittance using lights, in other words, from light point of view.

But I am facing some difficulties about accessing properties such as shadowmaps, shadow position, light far plane, etc. as it seems to be really different considering directional lights, point lights, spots, etc.

I can access the _ShadowCoord or the _LightMatrix0, _LightShadowData, _ShadowMapTexture, etc.

Edit: The question was edited.

 

The question was a bit badly formulated so I edited it.

 

Yes you can access such shader uniform in your own custom shader.
They are just common uniform.
Read unity build-in *.cginc and use it as you need.

 

Thanks for your reply @StevenGerrard, do you know how can I retrieve the directional light depth ?
