After unzipping the .zip file, you will see all the files included in the product.
The Blender file has all the paths set to relative to avoid conflicts of missing textures. For that reason, we recommend that you always keep the textures and the Blender file together in the same folder.
If the textures are separated into a different folder, you will have to load them back into Blender by hand, or following the command File – External Data – Find Missing Files.
The Blender file is ready to render. If you have kept the file structure as it was in the .zip folder, when clicking Render Image your rendered image will appear in the top right window of the Document.
