Why Symmetry node has only a Color version and not a Grayscale?

[Cristóbal Vila]

Why a so basic node as Symmetry has only a Color version and not a Grayscale?

This forces us to use two extra nodes (hence, add complexity)

• A Gradient Map to convert from gray to color

• And another Grayscale Conversion to convert from color to gray

The Mirror node (as many other basic ones) has both versions, Color and Grayscale. But not so Symmetry.

Not a tragic thing, but it seems like an incomprehensible forgetfulness or absence…

You can make your own SymmetryGrayscale based by modifying a copy of the existing node.

Right Click on the Symmetry node and Open the Reference

In Explorer, right click and Save a copy As' of the graph with the new name e.g. SymmetryGray

Open that new graph

Change the input node from a Input Color to an Input Grayscale node

Save the graph

It will not appear in the node list from the spacebar, but you can drag it into a graph where it will act as a node when you want to use it.

YESSS!!

Thank you so much, Dave!

I just learned a great lesson. And storing this node in my Assets Library I can access through Spacebar.

Now I just need how to create/change a new (greyscale) icon for that node… but this is not so important. Just a cosmetic thing.

Very appreciate your help, Dave 🙂

Glad to help. It is also useful to understand how some of the nodes work, for example by looking at the function graph within them.

That is, for sure, something that I will do from now on! 🙂
Thanks again, Dave.
