I would like to start developing my own shaders within unity.
For starters I would like to do a screen spaced blur.
Are there any good tutorials to learn shader development besides the official unity documentation, which i find a bit hard to understand?
I think this is what you are looking for: http://en.wikibooks.org/wiki/Cg_Programming/Unity. The tutorials are organized in an increasing difficulty order and each was written with Unity in mind.
Easy to understand tutorial
And the following wiki book helped me much
Don't forget Jessy's video tutorials
And some Unity3D resources really helped me to build up the basics
