Using the Oculus Touch and HTC Vive motion controllers, your movement in the real world is mapped one-to-one in VR; you can reach out, grab, and manipulate objects just as you would in real life.

You already know how to use this tool, because it works like the world works.

Well be showing more and announcing the release date at GDC on Wednesday March 16, 2016.

And when its released, it will be a built-in feature of the freely-downloadable Unreal Engine, with full source on GitHub.

Creating Vr Content Mod Makers To

The same Unreal Editor thats used by everyone ranging from indies and mod makers to triple-A development teams with 100,000,000 budgets.

But you can also use a smartphone-like pinching motion to zoom in and out.

With one pinch, the world is shrunk to the size of a Barbie Doll house on your table.

You can manipulate it granularly and ergonomically, and then zoom back to human scale.

Or teleport to the laser pointers target location with a single button click, inspired by Bullet Trains locomotion.

Scroll, press buttons, tweak Object Details, interact with menus, drag objects out of the Content Browser and drop them directly in the world.

In VR, you can frequently accomplish the same result with a single, intuitive motion.

This should come as no surprise, as a mouse only tracks two degrees of movement (X and Y), but in VR your head and two hands track six degrees of freedom each: X, Y, Z, and three rotational axes.

You could roam around the environment, place objects, and move lights, all in real time.

We take this for granted now, but it was pretty revolutionary in 1998.

Unreal Engine 4 introduced Physically-Based Rendering and a slew of new features that together achieve an unprecedented degree of photorealism.

This breakthrough is the brainchild of Epic technical director Mike Fricker, who began prototyping the concept back in 2014 on Oculus DK1.

I thought the idea was a little bit crazy because the Unreal Editor demanded precise controls, while early VR hardware struggled with low-fidelity input.

You can manipulate 3D objects in 3D with the motion controllers just as you do in the real world with your hands.

Mike Frickers pioneering implementation brought the same magical feeling of using an iPad for the first time: Your brain already knows how to use this thing For me, VR editing feels so real that I have dreams about it.

Some parts of it are awesome right now, others parts have rough edges, and were rapidly advancing on all fronts.
