Well, you are right about the stealing part.
I doubt axel1994 was asking for the name of the feature, but was instead was interested in a brief high-level description of what the feature is -- the same I tried asking for earlier in the thread.Since i'm the one that'll make it, i'm still deciding the name.
This doesn't need to spoil the feature if you're concerned about someone "stealing" it -- it could be just a high-level statement like "it's a new rendering system based on radioactivity", "it's an AI system for making groups of people accurately simulate people getting on a bus and how they relate to the other passengers", "a new way of dynamically altering terrain based on erosion".
It could also be more technical -- "something to allow the developer to automatically texture, set up UV coordinates, etc. any given 3D model (regardless of complexity) within 1 minute".
What slightly confuses me is how you seem to certain that none of the current engines support it, given your current knowledge of programming.
While a feature might not be a bullet point on an engine's feature list, it might be possible to implement using the engine regardless.
This is what it is: "something to allow the developer to automatically texture, set up UV coordinates, etc. any given 3D model (regardless of complexity) within 1 minute" and automatically model it etc.
Do you think any engine that had that will not want game devs to know?
The design of the engine, who it can be used by, what the engine can create with/without coding, what it can teach and its price and some other stuff, is what will make it different.
You mean like Unity that allows you to swap out sub-meshes with different textures? Also allow's you to delete submeshes and you can actually cheaply buy a small add on to create other meshes. All rigging can be done in mecanim if it has bones..!
