What are the limitions and things to consider when creating and selling warfare equipment assets?

Hello!

I am interested in creating 3D assets for a modern warfare theme, including guns, vehicles, and planes. I aim to create replicas of real-life equipment but in a cartoonish style rather than a photorealistic one. I would like to ensure that I stay within the legal spectrum while keeping the models as close as possible to the original designs. I understand that using real-life names of products is a big no-no.

I would appreciate guidance on the following:

1. Is it permissible to create replicas of real-life equipment for the purpose of creating 3D assets in a cartoonish style?
2. If obtaining a license is required, what steps should I take to ensure that my models are legally compliant without one?
3. Are there any specific guidelines or restrictions from Unity regarding the creation and sale of these types of assets?

Thank you for your assistance in clarifying these matters.

In the following, I have an image of one of my models and an image of the real thing to demonstrate.

 

There is no legal spectrum. There is only lawsuits. You may 100% accurately remodel an existing brand item and get away with it. You may perfectly modify design features of that brand to make it „safe and legal“ and still get sued (or rather: takedown notice etc blabla lawyer bs).

That said: you will not be able to get a license.You will be relatively safe even if you model it close to the original as long as you significantly alter or remove recognizable brand markings (logo, name, prominent design features). No company cares about you small, measly, amateur artist whatsoever. But people buying from you who may get sued may hold you responsible and squish you like a grapefruit.

Anyhow: use common sense. Stay away from accurately modeling prominent brand features and you will be fine!

PS: the CIA is on to you. They‘ll be watching. Sleep safe.

 

That was very helpful and informative! Thank you for taking the time to answer me!
