CREATING FOR VR: PRO TIPS

THE EPIC GAMES ART TEAM SHARE WHAT THEY LEARNED FROM MAKING ROBO RECALL 1. Prototype in Vr

To save some time during development, create prototype meshes first and test them in VR. What looks good on your monitor might not translate as expected in VR. Refine your prototype meshes further, then test again. Continue to iterate and make changes as needed and only proceed to the time-consuming detail modelling of objects after you are satisfied with how it feels in VR. Unreal Engine 4 makes it quick and easy to reimport updates to your meshes, and you can also easily enter and exit VR to test them.

2. optimise for Vr

When you develop for VR, you have to constantly optimise your assets to make sure the game always runs at 90fps (frames per second) during every phase of the production. If you don’t run at a rock solid 90fps, you could get motion sickness and not even test your own game. Fortunately, Unreal Engine 4 offers plenty of tools to profile performance and optimise scenes.

3. make animation Precise

In VR, players can be so close to the action that the precision of each animation is even more important. Make sure there are no sliding footsteps, no objects penetrating the ground, that bodies react to impact and robots always look at you, and so on. All of those details add to the quality of the experience and the player’s sense of immersion. Unreal Engine 4 has tools to layer animations and add small corrections where they are needed. Also, we have developed an important feature called physical animation, which enables you to drive simulated rag dolls towards an animated pose using things like forces, torques and motors.

4. Use sprite orientation mode

When making VFX for VR, materials applied to sprites break down and look fake and flat. To solve this, Unreal Engine 4 has a new Sprite
