When modeling objects for use in an engine do they have to model them from scratch every time?

When modeling objects for use in an engine do they have to model them from scratch every time?

Is there any sort of way to "scan" items/objects that can be recreated in modeling software?

You are fucking kidding right?
Most human faces and props like shoes and backpacks are scanned. The rest is outsourced to chinks.

retarded question

also yes you can 3D scan objects for use in 3D modeling software, with lasers or cameras, anyone can do it, you'll have to translate the point clouds to polygon models though and you need to run it through some LoD tier algorithm which simplifies it heavily

I understand motion capture.

What im saying is can they scan 3d objects and re-create/texture them in an engine?

vanishing of ethan carter heavily did this

Star Wars: Battlefront used photogrammetry for most of their environments, where you can just take photos of things and turn it into models and textures.

That was mostly organic models and also they scanned in some movie props or something, but I'm pretty sure the process for all of that is called photogrammetry.

The majority of 3d objects in games are scanned

So basically you're trying to ask "Hey can I take a picture of this rock and manipulate it as a 3D object in Maya?"

and the answer is yes, there's free software to do this, you just need to take a trillion images of the object and wait a few hours for your PC to map all the points and create the point cloud model

>you just need to take a trillion images of the object
Depends on how accurate you need object to be
for practical uses, 3d mesh still have to be manually done over scan and then the scan is used to create normal map

Yea I remembered that time Squenix showed us that rock asset that they scanned i to the game.

They had all the tools, Marvelous Designer, Crystal Tools and if I'm not mistaken they have that license for the Yebis post processing program also

yeah, actually you can also just have an algorithm simplify the object just fine (a little manual fixing might be required to remove floaty bits) and then have another one mapping it to polygons

it's probably more time consuming in some cases than just creating the model to be honest

Yes. EA games use that tech, which is why Battlefront looks so gorgeous and can still run on toasters.

A friend of mine works in landscaping and they regularly use laser nodes to scan the entire surface area, in order to model projects in 3D.

Judging from this video, we might no longer see job ipenings for 3D Modeler in mayber 2-3 years.

Technology really is unpredictable and frightening

The technology is like 15 years old and I wonder where you plan to get a real dragon to scan

valid only for boring photorealism looks.

you model it from clay and scan it, already done

of course you need modelers still but makes it more intuitive for artists

There are many scan techniques, but it all depends what you want to model.
There are even scanning apps, like this 123something thing from autodesk.

I feel you, my man

>you model it from clay
Lol, have you ever heard about Zbrush?
Actually talking heads from fallout are made by plotting vertexes from latex masks. Then during XCom Apocalypse Microprose hired artist to make sculptures to scan but like everything with the game it ended up as complete disaster. No one does this nowadays

This isn't true at all.

Faces and shit like rocks yes but not the majority

>Is there any sort of way to "scan" items/objects that can be recreated in modeling software?
It's called photogrammetry.

Activision pretty much scans everything for cowadoody

yeah I have used zbrush

The environments and props in Battlefront are stunning.
