Can someone extract 3D models from unity players?

[VIC201]

I just ask because of the restrictions from some 3D model sellers like this one:

Game developers : all is well as long
as no one with normal wits and average
criminal energy can extract the models
from your application and re-use them,
it is always best to convincingly discourage
such people - this is really all we ask,
apart from a copyright notice
if your application is likely to be spread
more than 100 times, or, at an exhibition,
shown to more than 100 people.

I recall someone saying that: “If it’s in memory, someone can snag it”. That said, it would take some serious knowledge to extract models from memory. So you shouldn’t worry about that quote, as it takes way more than “normal” wits to get a model that way (I wouldn’t even know where to begin ).

The people you quote have to be reasonable about model extraction and it seems that they are. Don’t worry, you should be ok.

Unity encrypts your app by default, I think.

it does?

I am just wondering cause I don’t believe that is true. but maybe. I’m not totally sure either so …

It’s actually really easy. You just need to know where to look. There are also model/map/sound/etc extractors for all kinds of games, from first party Nintendo stuff(amnoid.de - welcome) to the latest Unreal Engine games. From what I’ve seen, a reasonably skilled programmer can get at this stuff if they really want to without a huge amount of effort. Unity keeps things locked away just as good, if not better, than many other engines. I don’t think there’s much to worry about from a license standpoint.

That really depends what they mean by that. Most big bucks games out there don’t employ more restrictions on model data than unity does. All models and all other data is packaged into one proprietary data format. So its not as easy as just knowing which directly to look in for a zip file.

On the other hand, as stated, its on the client computer. With enough willpower and time, the user can get to anything.

Is this flatout2 unity demo made with help of 3DRipperDX?

I don’t think so. IIRC, this was posted here in the showcase forum quite a while back and included some background information on how it was done. I’m pretty sure you’ll find it if you search.

there also is glintercept. capturing meshes, textures and shaders is as easy as taking a screenshot.
