I give to your attention the drone DJI Mavic PRO 2
!!! MORE VIEWS can look here:
Who works in the V-Ray version is lower than 3.1. Be careful, in the materials in the BRDF section there is a Microfaset GTR (GGX), if your version is older than 3.1, then the BRDF field will be empty. Choose Blinn, Phong or Ward - which is preferable to you.
For Corona render, it is recommended to install a version not lower than 1.5, since the glossiness of materials is adjusted to PBR
Enjoy using and successful projects =)
