In the archive, there is a 3ds Max 2017 scene with Corona and V-ray + fbx files. Previews are rendered in Corona Render 13. The models use Corona Legacy Mtl. A version of Corona no lower than 1.5 is required. Material conversion to V-ray was done using the V-ray scene converter. The scene includes a model of a black chokeberry bush 374 cm tall; if necessary, you can remove the moss by selecting the polygons by ID. Polys: 1022016 Verts: 1576192 Objects and materials in the scene have logical names. "For Corona Render, it is recommended to use a version no lower than 1.5, as the glossiness of the materials is set with PBR in mind. Those working in V-ray versions lower than 3.1 should be careful. In the materials section, BRDF is set to Microfacet GTR (GGX); if your version is older than 3.1, the BRDF field will be empty. Select Blinn, Phong, or Ward - whichever is preferable for you."
