I like creating game with unity and i upload some of my games to gaming sites like kongregate for example but most of my games have horrible graphics and are just blocks, but i would like to extend further in terms of creating a game with better graphics. But my problem is that i cant create 3D models and i cant afford to hire a 3D modeler. So i thought of the solution of using models off the unity asset store but my question is: Am i allowed to use free models/animations on the unity asset store in my game even if the game is used commercially?.
Generally, yes, you’re allowed to use free models commercially, however you should check if there are additional restrictions placed on the model and they’re compatible with your goals. (They would show up in “license agreement” link on asset store page)
For example, “Unity-chan” has its own license agreement with additional restrictions:
How do i know if a model has “additional restrictions”?
See the license included with it in the file or the host site. If there is none then avoid it.
They’re explicitly mentioned on item’s asset store page.
If there’s nothing mentioned, but it is on unity store, then it is covered by store EULA.
If it is not on unity store and has no licensing info, then using the asset is risky.
So your basically saying that if its on the unity asset store and has nothing mentioned about any additional restrictions its alright to use?. Does the same applied for payed models?
You can email an asset publisher and ask them if you can use it in a game that you intend on selling.
On the publisher page there is “Support E-mail”, which you can use to ask questions.
As far as I know, yes. There are restrictions though: by default you are not allowed to resell assets you bought on asset store.
If you still have doubts, contact unity support. I think they’ll reply you eventually.
Interesting point - I kinda don’t agree with it - could you clarify why an asset without an additional license beyond the asset store EULA should be avoided?
My opinion is - If there is no additional licensing restrictions from the asset creator - the asset store EULA covers the asset. There is no risk of using any assets on the asset store for commercial purposes - as long as you abide by all user agreements.
One exception I can think of is the 2D character sprite pack which is created using Spine, and packages the spine run-time within the asset. Spine EULA requires purchase of the external basic spine tool in order to use the asset store package.
Hmm seems I somehow managed to miss the keyword asset store and previously answered generally speaking how to handle free models from the net 
So yeah, if there is no separate license then it’s the default asset store one.

Easy answer. If it is from the Unity Asset Store, paid or free, you can use it for a commercial game. The only exception is if the owner provides additional licensing requirements, which you must follow. The vast majority of assets on the asset store do not have additional licensing requirements beyond the EULA from Unity itself.
I disagree with some of the advice above. I think it is redundant (and probably annoying) to email every provider and ask them if their package can be used in a commercial game. When the provider uploaded their package without additional licensing agreements, they basically already gave you/everyone permission to use the package in a commercial game.
Maybe me, but if I put something on the store for free, it would annoy me to have to answer 5 emails a day asking me if they could use the package in a commercial product. Yes yes… that is why I uploaded it without any additional licensing agreement.
Oh yeah - I completely agree if coming from another source other than the asset store - a random website hosting a free 3D model without a user agreement - should not be used in a commercial release. Good point Ostwind.
