Blender as Compositing-Tool

“Blender as Compositing-Tool” by Berthold Grünhagen
If not, simply drag-and-drop the node-connection from one to the other.

For rendering out and preview the compositing you have to add 2 more nodes ( output-nodes ):
ADD – OUTPUT – COMPOSIT (for rendering)
ADD – OUTPUT – VIEWER (for preview)
The preview can be showed after pushing the BACKDROP-button on the bottom of Blender.

Change the compositing by changing the values. Just left-click and hold the left mouse-button in the value-field of your node and move it to the left or right. You can also put values in it by left-clicking in the value-field. Now you should see the results in the preview!
•  Adding your passes
In our CG-Tool we rendered out the passes Color, Diffuse, Shadow, Specular and Zdepth.

Now we put our passes (here Color and Specular) together. To do this we need a MIX-node (ADD – COLOR – MIX). The FAC value sets the power of the influence of the added pass or node (here: the second image).
