[jitter] Re: Re: building a jitter app with shaders included

Hi Karl,

It should load the file either way (written into the slab as an  
atribute or loaded with the file message). Just be sure you include  
the file and the spelling is the same.

  I think you do not need to add the cg.framework anymore. It knows to  
do that on the compile. That was for jitter 1.5 I think. Try it  
without doing that.

I don't think that including the shaders in the build script works.  
Because they are loaded later and wont be found when compiled in. But  
I could be wrong about this. Never tried honestly. I just added them  
to the package/contents/support after the build.

> [jit.gl.slab obama @file cc.uyvy2rgba.lite.jxs]


nice context there! are you sure you included the  
"cc.uyvy2rgba.lite.jxs" shader and not just "cc.uyvy2rgba.jxs"?

It should find them, even when written in as an attribute. But I guess  
the work around is to load you shader files after the app has loaded.  
But it should just work as an attribute!

I also, for organization, have all my shaders in a folder that I add  
to the package/contents/support folder and it still finds them. That  
way you can make a folder with copies of the shaders you are going to  
use and just add that folder each time after you compile. Makes for  
faster workflow.

Good it works, the rest seem to just be idiosyncrasies.

cheers
