I am a 3d modeller, I see online a lot of sites which are selling 3d models with brands on them, example: ferrari car, HP laptop, Sony Playstation. So I had a model of a construction crawler crane with a brand on it. Should I remove the brand before selling it? Thanks. by 3d modeller i mean 3d max modeller, a computer software. So it's not a physical item. I am using Autodesk 3d max software. Thanks guys for the answers really helped.
