Recently, the Castor3D engine was updated to version 0.17.0. The new version has many improvements and innovations. For example, a debug box was implemented, allowing displaying AABB and BVH cluster lighting. Support for MSDF fonts, support for diffuse transmission, support for webp images, and basicu images was added. CastorViewer can now directly open files from an external 3D file format. Reflections from a procedural sky were implemented. A method for displaying a light map instead of a skybox was added. Anisotropic specular Disney BRDF was implemented.
Details are in the official changelog. The new version is available for download.
