The children's climbing frame is an essential element of any playground. Playing on the climbing frame develops a child's balancing skills. Active movements in the fresh air, with a large influx of oxygen into the body, stimulate both physical and mental processes. Muscles are actively formed, the child becomes stronger, more agile, and skilled.

For those working in V-Ray versions lower than 3.1, be careful, as the materials in the BRDF section use Microfaset GTR (GGX). If your version is older than 3.1, the BRDF field will be empty. Choose Blinn, Phong, or Ward – whichever is preferable for you.

For Corona render, it is recommended to use a version no lower than 1.5, as the glossiness of materials is set with PBR in mind.
