I created a video to show the potential of the Vulkan renderer included in my framework. Now the engine can import 3D models from several 3D formats (including collada) and render them with Vulkan libraries.
The engine is equipped with a proprietary material system and mesh format. The materials of the imported models are converted to the engine's materials format which is then converted into the shaders that are used to make them work. As you can see from the video, the engine is already capable of rendering millions of triangles at high framerate and resolution (3840x2160).
