Nodes can be daunting if you’ve never used them before. In this video I try to explain some basics of how to use the Cycles material nodes to colour, overlay and combine a couple of different images using “factors” and also adding transparency.
Sometimes we would like to exclude or mask an area from being affected by texture painting. It’s possible to use the face masking button, however for more control it’s easy enough to paint or generate a second texture to mask the effect of the paint.
Virtually everything in Blender can be referred to as a “Datablock” At times this behaviour can be confusing! Hopefully this video will demystify the Datablock concept somewhat. How to link datablocks between objects and how to unlink them and generally get a feel for what it’s all about.
How to use the material slots to apply multiple materials to an object and then placing a different image on the faces of our default cube
A quick look at how to use the nodes to create double sided materials to apply to opposing sides of a plane, and how to use texture layers to put different images on the front and back.
