One object per gig. That means if you would like image consisting of 4 different bottles, it is 5 gigs total, 1 per bottle and 1 for composite image.
Design of label not included, so you need to either provide your own label or order gig extra. If you require complex labels, you might need to order more gigs. Ask if unsure.
Custom 3D objects start at 13 gigs per hour, and amount of time required varies based on object.
If what you want is simple for me and you have proper files, I will take care of your order expediently. I decide what is simple for me.
If you require 3D book mockup look at my gig specializing just in 3D books.
Best results can be expected if you provide images sized 3000x2000 and above at 300 dpi. Depending on item in question smaller images might still look good, but quality of what I can give you begins with you.
