Blender 3D – using nodes – part 001.

Compositing is used quite frequently in Blender to make rendering faster, add images, make distortions, make the render look more realistic, and much, much more. Used with nodes – an entirely different way of visualizing the graphical programmable shaders , 3d and rendering.
First open your Blender 3D and go to : Compositing.
In this tutorials I just show you how to deal with nodes. So you need to set your render and / or your material object from scene and will deal with that. You can used Shift+A keys to add your nodes.
You can select one node or multiple nodes if you use the Shift key.
If you have many nodes then you can use M keys to mute the selected node.
This will bypass the entire node / nodes and will reconnect the first with the next node.
The Ctr+X keys will delete the node / nodes .
The Alt+D will disconnect the node.
If you want to duplicate your node / nodes just use Shift+D keys.
You can duplicate your node / nodes with your connections then use : Ctr+Shift+D .
Some connections will be the same from one node to many nodes.
You can put together with this:
– select your nodes connected and then drag with your mouse over connection with CTR key pressed, see this next steps :
