For example to coloring a Text on a middle layer part, i need to define just a region of the object to process it independently from other FFF's. Till now it's only possibel to define different settings of several layers.
Thanks for your request! I agree it would be really helpful for a lot of different use cases to specify regions in 3D where processes would be applied.
