specular matrix for mesh - "invalid input type" meassage

    Feb 13 2014 | 1:24 pm
    I'm trying to draw particle system with gl.mesh object.
    I send vertex matrix to mesh first inlet and get my 500 cubes.
    Then I send color matrix (float32, 4 planes, same dim as vertex matrix) and get my cubes colored.
    but I have to set mesh attribute lighting_enable to 0, in order to see the color.
    and then my cubes don't react to light - they dont have shadows.
    I' trying to send specular matrix to mesh' 5th inlet, but get message "jit.gl.mesh invalid input type" in max window.
    I've been trying float32 and char, 3 or 4 planes, but still get this message.
    I found somewhere in forum, that this specular matrix should have same dim as vertex matrix, but from where comes this "invalid input type"?
    draw_mode is "quads", I tried auto_normals, auto_tangents, sending normal matrix, still the same problem.
    Any help, or pointing out to search will be appreciated.
    * I'm doing the stuff with max5 for some reasons (had some problems to move to max6, even though I do have it)
    thanks, Sakerdon
    here is example patch, which draws 1 quad for simplicity.
    I'm getting "invalid input type", when setting matrix "spe" to val 1 (step 5)

      looks to be a bug.
      thanks for the report.

      any results / updates on this bug?
      I can't attach anything to the specular array input without throwing "invalid input type" errors
