• Physically Based Lighting - Part 2: "Emission ,"
• Exposure - Part 3: "adpat"
• Materials - Part 3: "GLass"
• Probe Volumes - Part 2:"Project Settings > HDRP Global Settings >" should be "Project Settings > Graphics > HDRP Global Settings >"

Confusing tutorial steps:

The following might just be user error on my part, but I've noted down places where I got stuck following the steps.

• Materials - Part 2: There is no Ball_PF gameobject under Props > Room 3 >. I continued with the tutorial step using Structure > Room 3 > UnityMaterialBallSmall > Ball > Ball Part
• Probe Volumes - Part 2: In step one of this, it says to disable "Probe Volumes". I think the setting name is "Adaptive Probe Volumes"? It took me a moment to realise this.
• Visual Effects - Step 4:

** The steps for this don't seem to work at all. In the Spawn block, Count is a property that can't be edited in the graph. You can set the default value but it will not change anything. I got this working by finding in Hierarchy VFX > Butterflies and setting properties in Inspector.
* Path is said to be {}Art > Particles{}, but it is {}SampleSceneAssets > Particles{}.
Light Layers - Step 3: It says "notice that the {}Light Layer{}", but I couldn't find "Light Layer" on Light_Spot_1200lm. I assume that this is "Rendering Layer Mask", but that is not clear as a new user.{}{}

Tested on (OS): Ubuntu 20.04
Notes:

• Tested in 6000.0.0f1 (HDRP 17.0.3), did not regression test.
