The default vertex and fragment shaders are missing from the COLLADA_RT distribution. The shaders directory has a Makefile, but I cannot find any of the *.cg files. Does anyone have these shaders?
Those shaders aren’t used anymore.
The fact that the directory and makefile are still there is a mistake.
The code in the RT that dealt with those shaders is dead code now. The COLLADA FX Loader library takes care of any cg shaders needed. Those shaders referenced in the makefile were used before the CFXLoader existed.
We are slowly stripping out dead code from the RT.
