What is included: 3D hot water bottle model in the upright and laying down positions, the rendered images, and the model's blue, green, orange, red, roughness, and metalness textures/maps. Colours may vary from the preview images depending on the lighting in your scene.

The camera, lights, and plane that were used in the preview image are included ONLY in the Blender file. I used Blender 2.79 for this 3D model. In order to achieve the same renders you will need to use the free HDRI 'georgentor' in the background. You can download it from HDRI Haven. All of their HDRIs are completely free and licenced as CC0.

For Blender Users:The subdivision surface modifier is present (not applied) in both Blender files and set to 2 subdivisions. Shading is set to smooth. The node setup is included in the Blender file for the models' materials, but the texture files will need to be added or the models will appear purple when rendered.

All formats:Both the low-poly and high-poly models are packed in the zip files for each format, except the Blender file (remove the sub-div modifier if you want to use the low-poly model in Blender).
