As Blender grows it increasingly is using Nodes for creating new procecural objects. Both the Shader Editor and the Geometry Node Editor are used to create procedural materials with Nodes. Although the nodes are not the same, how they work is the same.

I will use the Shader Editor to look at basics that are common to all node editors.

Node Wrangler – this should always be installed if you are going to edit nodes.
Helpful hotkeys with Node Wrangler Installed
– ctrl-X delete the node(s) and keep the connections
– ctrl-t Add Texture Coordinate and Mapping to Texture
– Ctrl-shft- click on node to see effect of node

Bouncing Blcoks demo of my cube
see BasicLayout.blend – cubebounce.002

1. Set collodion on the plane (or object) used as the floor
   2. Go to Properties ‣ Physics and choose Soft Body. Uncheck the Soft Body Goal, and check Soft Body Self Collision. Also, under Soft Body Edges, increase the Bending to 10.

You may want to create a Basic Layout for each of you main Blender Functions, Editing, Video, etc. Note that what I call a Basic Layout is basically the same as a Blender Template. The difficultly of creating a Template is that you must manually create a folder.

World versis Object settings

Once you have created the folder you can create the layout or template that contains the features you need.
A major part of your layout will be the world background the you set up. When you first begin you will probable want to just stick with the default settings. These settings do not work for me because I do not have very good vision, so I make a few very simple changes.

World Background.
– I generally use a solid black
– Your setup may include a HDRI
–HDRI setup – This is an option as you become more experienced and need more sophisticated lighting.

====================
My setups for opening in a :
-Basic Layout for most Blender modeling.
– background solid black
– basic materials (colors)
–

– Opening in the Video Sequence for Video Editing

World Background Setup. Remember that the World Background does not include a light source.

Finally back up after being down for two days. Not happy with Blue Host. Somehow they messed up my SSL certificate and getting it re-registered was a pain.

Blender Dynamic Sky
This is an new addon as of Blender 2.8 called Dynamic Lighting. see video. I am sad to say that after a couple of hours playing with the adjustments I am very disappointed in it. Probably just me.

Blender Manual – very good

!!! Warning =  “The Dynamic World could not be found in the Worlds’ Data – this message caused by not having Render set to EEVVEE !!! Also make sure you are working in a blendfile that has been saved. Should work in cycles onece everything is ok.

Additional Methods to cut a hole.

An example of an easy to make extrude item.

1. 
   Open Blender to new layout.
   Select the default cube
2. 
   Add catmull-clark modifier,
   set multiplier to 5
   Leave render at 2.
3. Start Extude/Size sequence
   

Detail Video -Teardrops.
The basic sequence is:
extrude – resize – extrude – resize.

What is a vision friendly site. It is a site that does everything possible to reduce white backgrounds on a screen. This site does use white text on a black background for a better contrast,
If you truly have bad vision,as I do, and you are overly sensitive to a bright screeen you should turn on the Microsoft High Contrast setting in the Ease of use section of the Control Panel.
This video gives details. It is unfortunately done with High Contrass off so for me it is difficult to watch. I will try to remake it at some point with High Contrast on so it is less painful to watch.

If you use google Chrome you can add an extension that will make most pages open in dark mode. Go to chrome settings and select themes. Download a dark mode theme. You will have to activate the theme with the extensions widget at the top right of the screen.
