Standing interior fun 3D model

cgtrader

This standing fun model is modeled in Autodesk Maya 2022. The UVs are laid out. materials are applied. the all mesh is grouped under Fun group. The renders in the preview are done using Arnold's renderer and no post-production in the images. I have viewport smoothing applied to it by pressing 3 on the keyboard. to remove that smoothing select fun group and press 1 on the keyboard. the HDR image used in the rendering is attached in the files. apply it to the dome( sphere) around the model.
