Image (c) Daly Realism, 2019. Licensed as CC BY-NC as a combination of the Damaged Helmet model and Yokohama Park environment map.
From the sources:
[creator] Made with 3ds Max, Substance Designer, and Substance Painter. Based on a concept drawing by Oscar Cafaro.
Pre-glTF version at https://sketchfab.com/models/b81008d513954189a063ff901f7abfe4#comments
[Khronos] The original model was built on an early draft of glTF 2.0 that did not become final. This new model has been imported and re-exported from Blender to bring it into alignment with the final release glTF 2.0 specification.
Used directly as glTF without any futher conversion. Environment light maps are not part of the model and are applied separately. The environment map used for the image is Yokohama Park.
