Bake textures on button press / only cook part of a node tree on request?

[ron2812]

Hello everyone!

I was wondering if it's possible to temporarely activate one side of a node-tree to do some texture baking via a button on the UI of a digital asset?
Once the baking is done, this part of the tree should stop cooking.
In a nutshell, i wanna be able to create a procedural model and once it's done, just hit a button to bake out textures (depending on the model)

I'd like to try this in Unreal so my idea was to have digital asset in UE4, adjust some parameters to create a variation of my model and hit a button to generate the textures (curvature, normals from HP/LP, you name it..)
which i can then import into the engine and use on materials.
If i need to change the model I wanna do adjustments, rebake textures and refresh them in UE4.

Is this possible?
And if yes, can someone point me in the right direction?

Thanks in advance!
Ron
