How can I change this black color in a procedural texture of Astrocyte?

This is an astrocyte (brain cell that relates to Alzheimer’s disease prevention).

I would really like to be able to adjust my nodes so that I can make the black color transparent or translucent. Appreciate any ideas. Also appreciate any feedback or suggestions - mesh creation of organic shapes is still eluding me!

The black parts of your model are black because the normal are facing the wrong way due to the way you have used the colour ramp in the displacement slot. Essentially your bump map is too harsh.

The best way to mix transparent and color in your node setup would be to:

  • Plug a transparent shader into the bottom slot of the mix shader.
  • Remove the Fresnel node.
  • Replace the gamma node with a math node set to “Multiply” and make the multiply value around 0.1 (to start with).
  • Take a noddle from the output of your colour ramp node and plug it into the fac slot of the mix shader.

Thanks Moony! Im gonna work on it and see how it comes out with your changes. Nodes can get pretty deep!
