“The Medieval4D toolset is a combination of both a simple 3D modelling program and a ‘core’ catalogue of pre-built 3D objects and textures. To create medieval structures such as houses, Inns, shops etc, you simply drag and drop these objects in to the modeller then move/rotate/scale/texture them as you see fit. You can then export the finished model in .x format to be used directly in your games.”
