VVVV Gamma ,Make the black parts in the texture transparent

vvvv gamma question

I want to make the black parts in the image below transparent, but I’m not sure how to do it. Is there a Node or NuGet package that allows setting transparency based on color, or is there a better approach?

If you want to make a mask and blend it with another texture use a Blend node!

I would suggest to do it so:

  1. Take any texture
  2. Make it Black and White in any way you like.
  3. Apply this BW as AlphaMask for SetAlpha.

In your example, you just need to make a contrast higher, so that the gray area will be white.
