IMPORTANT - READ BEFORE PURCHASE
Note: Renders shown in this page are for showcase purposes only. Render set-up [Illumination] is not from Blender but a live-viewer and is not included with your purchase. Any 3D model you see in the picture is exactly the same, no changes, so you can recreate these renders as you need or better. Renders are only or will be included if I state such thing in the description of the 3D model as for its contents. Often or whenever I can. I post a screenshot of the 3D model in Blender, so you see what the 3D model looks like out of the box. I want to be honest and sincere with you [client]. So just a heads up. Consider before purchasing. Thank you for your understanding.
