You can use *any* 3D modeling software to create 3D meshes Blender is only one of the modeling tools supported. We support many standard formats for 3D and 2D data (reading and writing), like X3D, VRML, Collada, OBJ... So in practice you can use any software that can export to any of our formats. See e.g. https://castle-engine.sourceforge.io...ata_export.php where we show also how to export from 3ds Max or Maya.

Also, you can create your own editor on top of the engine classes, definitely. You can build and modify our scene graph (the graph of X3D nodes) at runtime, and create a 3D editor, where you can edit existing models or build new ones.
