Just started work on a new project which I’m hoping will have turn out to be pretty nice looking … however I’m still way behind the curve on this 3D stuff.
On to the main question:
Are there any existing shaders that support bump mapping for iOS devices in Unity 3?
(Or do the default ones work and I just have to enable OpenGL ES 2.0?)
And some related questions that I would love an answer to if you have time 
What’s the performance like?
Where should I go for good tutorials/sites about shaders with a focus on writing for iPhone/iPad?
the default ones work if you enable ogl es 2.0
But you normally likely would want to opt them far more through GLSL ES so you don’t do the rest of these shaders.
Also you want to opt them to not use more than one pixel light for example.
the amount of GLSL ES information is scarse, you will likely have to invest in the corresponding opengl related book
Hey thanks for the reply mate, I was hoping you were on
I’ve got no problems buying a book, any recommendations?
Generally, the OpenGL Shading Language book or the opengl programming library 5th edition in case you are interested in the ogl api too.
the stuff holds up to a given degree (ogl es 2.0 has no fixed function pipeline which also removes some macros for things. unity offers some of them again through its own internals and the glslinc )
Thanks mate, I’ll check them out (pretty sure the University library has the Shading Language book, although maybe not a recent edition).
Everyone else feel free to post your thoughts too
