How to get Worldspace Light Direction in ShaderGraph?

Hey there I found great example of rim light in Shader Graph by Keijiro
but I want to create directional rim outline shader, like in this example.
It suggests to apply WorldSpaceViewDir as rim offset.
Is it possible to achieve something like this with Shader Graph?

 

You can learn from his graph how it's being done. All the info is in the picture although low res. Ultimately you can download the project he made available free with that example as well as others and look at how he made those shaders.

No I mean I know how to make rim light but wondering how to make shader graph with rim only on the lit side like on second example link

 

In that example, they are using lighting functions but shader graph doesn't have any nodes for that yet.



Looks like you can use the camera view direction to mask the rim light from the camera view angle
Pretty sure there's a node in Shader graph for camera space

 

You can access unity builtin variables by create a property whose reference is that variable.

 

The above worked for me. Thanks @toothbrush.

Extra caveat for those on LWRP moving towards URP. It seems that built-in shaders variables shouldn't be exposed? This wasn't an issue on LWRP but moving to URP my shaders stopped rendering properly.
Luckily it's a simple solution: don't expose those built-in variables

Aforementioned warning:


Solution:


Uncheck those boxes ^^

 

Try to create a var Reference "_WorldSpaceLightPos0" But issue error : "Shader error in 'Master': redefinition of '_WorldSpaceLightPos0' at line 1297 (on d3d11)"

I also tried use custom-function of string type : manual use "_WorldSpaceLightPos0" complains that it not declared.

Any hint?
