Note: The scene comes set up with V-Ray as the renderer. To render with scanline you will have to select all entities and apply the standard multi-sub material.
Scaled to a 67 millimeter compressor wheel. Includes 2 different compressor covers. Includes both standard and V-Ray materials and textures. Uses 2 iterations of TurboSmooth and poly count is without TurboSmooth modifier calculated. The last 3 thumbnails were rendered with standard materials and default scanline render. The OBJ file has no smoothing applied and no materials or textures. Thanks for looking.
