Shader tool: Automatically mute nodes when not used

[Mustard2]

Check if this is feasible, and if yes, how to do it automatically and efficiently.

This should prevent Eevee to compile parts of the shader that are not used.

@Mustard2 something like this maybe?

Seems nice! Did you use one of the depsgraph functions to make it update automatically?

[cl3m3c7]

yes

[Mustard2]

As long as there is an option to disable this automatic behaviour and also an option to call it as a single-time button, this seems great.

As for the other features, since having depsgraph function can be expensive depending on the number of nodes, it's better to have an option to switch it off.

But impressive work.

yea, I was going to add a warning about the performance hit.
also for now, it does not handle all materials on activation, it works only on the material that has has changed. Also it was added in the advanced panel for a reason 😉

Ahah ok, when you have a working version just drop a MR and I can take a look. :)

Sorry I'm not having a lot of time lately..

[cl3m3c7]

okay, and no worries.
