jit.gl.node enigma (exclusively bluring certain textures)

    Hi all Here is a little patch that demonstrates that I want to perform gaussian blur on exclusively selected textures. I’m almost there But still one thing is missing. Any suggestions would be greatly appreciated. also, attached below is the leaf.png file endless thanks
    here is a link to the patch and .png file

      set the gl.node @erase_color to 0 0 0 0

      Thanks a lot Rob ,
      I had ended using a [jit.gl.slab @file co.lumakey.jxs] and played with the [param lumcoeff f f f f]. this was all guessing based on a jit.gl.pix patch from matmat (silicat).
      It is my personal goal to learn jit.gen and jit.gl.pix and I have spent a while including everyday this entire past week to try to learn jit.gen but I'm missing too much information that seems to be taken for granted by users who know the terms. I've made myself a documentation including :
      -Expo '74 by Darwin grosse https://cycling74.com/tools/expo-74-gen-patches/ -The BEK advance jitter workshop -the the gen patch a day patches -The Gregory Taylor Gen tutorial (swiz & Vector) -Gen overview Doc -Andrew Benson jit.expr article and help patch
      And so far all I've I've been able to do with jit.gen is
      [snorm] | [* n n n ] | [+ n n n] 
      as a more efficient way then [jit.expr] to control [jit.gl.multiple] ----- I do refer to wikipedia for help to understand what a [dot] dot product is [concat] 
      but it is not in the context of jitter. So it ends up going over my head.
      I would love to understand the following jit.gen patch. How lumakey works
      hoping Max 7 will have better gen explanation (tutorial & doc)
      Thanks again Rob for your @erase_color 0. 0. 0. 0. answer.
