com.unity.shadergraph 4.1.0-preview Package Notes

Moved `NormalBlendRNM` node to a dropdown option on `Normal Blend` node.
`Sample Cubemap` node now has a `SamplerState` slot.
New Sub Graph assets now default to the "Sub Graphs" path in the Create Node menu.
New Shader Graph assets now default to the "Shader Graphs" path in the Shader menu.
The `Light Probe` node is now a `Baked GI` node. When you use LWRP with lightmaps, this node now returns the correct lightmap data. This node is supported in HDRP.
`Reflection Probe` nodes now only work with LWRP. This solves compilation errors in HDRP.
`Ambient` nodes now only work with LWRP. This solves compilation errors in HDRP.
`Fog` nodes now only work with LWRP. This solves compilation errors in HDRP.
In HDRP, the `Position` port for the `Object` node now returns the absolute world position.
The `Baked GI`, `Reflection Probe`, and `Ambient` nodes are now in the `Input/Lighting` category.

Shadow projection is now correct when using the `Unlit` master node with HD Render Pipeline.
Removed all direct references to matrices
`Matrix Construction` nodes with different `Mode` values now evaluate correctly.
`Is Front Face` node now works correctly when connected to `Alpha` and `AlphaThreshold` slots on the `PBR` master node.
Corrected some instances of incorrect port dimensions on several nodes.
`Scene Depth` and `Scene Color` nodes now work in single pass stereo in Lightweight Render Pipeline.
`Channel Mask` node controls are now aligned correctly.
In Lightweight Render Pipeline, Pre-multiply surface type now matches the Lit shader.
