matrix GPU processing to texture : jit.gl.fbo: error initializing capture

    Hi,
    I am trying to move some matrix processing onto the GPU to be used as an intensity texture but cannot get it to work. What I have so far (based on an example by Wesley Smith) works when doing the processing on the CPU but when trying to do it on the GPU I get the following error message:
    jit.gl.fbo: unsupported framebuffer format! jit.gl.fbo: error initializing capture
    I am rather new to OpenGL (although quite a long time Max user) so I may miss something obvious. Does anyone have some hint ?
    Thanks in advance.
    Best, Julien

      jit.gl.slab outputs 4 plane textures, so i don't think this will work with @colormode intensity.
      if you really don't want to use jit.op for this, you could try jit.gl.pix.

      rather, you could try combining the rgb values from one texture with the noise values from another texture. jit.gl.pix will also only output 4 plane textures.
