    I'm getting some shader compile errors on load followed by a crash (which may be unrelated)

    The easy thing to do is just get rid of shadow support on vita (although I'm not sure what the shader platform define is), although from what I've read in these forums shadows should work.

    I really wish that it would log the actual shader program it tried to compile, because theres no way to know which line of the shader in question produced the shader compilation error.

    Currently this is a bit of a convoluted process, but in essence:

    1. In the editor, select the shader and click "open compiled shader"
    2. Isolate the section starting with "sce_vp_psm" / "sce_fp_psm" (search for the string, cut all lines before)
    3. Now the line number in the error (ERROR (331,35)) should almost match the source - you will probably have to add/subtract <5 lines.

    I just added some code to output the lines where the error is (+- 3 lines) to the console output - next update should have this fix.
