IT would be amazing to have the Houdini Engine integrated into the Xenko Editor. It allows you to create dynamic objects (eg a procedural geometry) in Houdini, and import it into a game engine as an object with parameters. After using this object as part of your scene composition the object is then baked for runtime.
As example would be to have a procedural rock object. This can be made in Houdini using volumes and all kinda fancy things. You might have an input parameter of a random seed, linked to a volume noise function in your rock generator. This object is imported into Xenko and many copies can be placed around the game scene. Each instance would have a random seed different value set, and therefore be a unique rock.
There is a free version of Houdini for non commerical / learning https://www.sidefx.com/products/houdini-apprentice/
And a very reasonably priced version for ‘low commerical’ https://www.sidefx.com/products/houdini/houdini-indie/
