    Hi guys,

    I'm really struggling to get this done.

    I'm aware I can get the "_CameraOpaqueTexture" texture via "Scene color" node, but I would like to access it from inside a custom function node in order to work with it via HLSL code.

    I tried this directly on the code...
    SAMPLE_TEXTURE2D( _CameraOpaqueTexture, SS, UV);
    ...and no success :/

    I tried too setting up a texture2d variable inside shader graph and changing the "reference name" as "_CameraOpaqueTexture" and then moving from there but ...no success neither

    any help or suggestion would be really appreciated

    cheers!

    Ok, it looks like finally I had some success...

    Two things are important here:

    1) it looks like you CAN't have a custom texture2D property if you have on your graph already the "sceneColor" node
    (even if you're not using it...)

    2) when you create a new "texture2d" property and you set its reference name as "_CameraOpaqueTexture" in order to get the "URP opaque texture" there... it is extremely important you disable the "exposed" property on the Texture2D properties section

    all this made the deal for me

    cheers!!
