Realtime PBR in Blender

Posted by Aidy Burrows on Aug 24, 2016

After this PBR video you’ll know…

  • An amazing great indie game project using Blender > Unreal Engine 4 = Swarm : Manchester. ;D
  • Several realtime PBR solutions for Blender that emulate the Unreal Engine 4 look and material inputs.
  • PBR sometimes stands for Professional Bull Riders.
  • You caught me out since this list is padded with non information such as this line.
  • How to quickly setup the experimental real-time Cycles build
  • Proper Fresnel in Blender internal and it’s limits.
  • A new blender game engine in development.
  • A sense of completion for reading all the way this far down the bulletpoint list. Bulletpoint list reading level up!

Real-Time PBR Blender internal file can be found here.

 

UE4 vs Blender

I’ve been texturing and developing for my own game project in Unreal Engine 4 – Swarm : Manchester. Something I found a growing need for was a real-time display of the UE4 PBR setup within Blender.

PBR in a game engine means we need these textures….

● Roughness

● Metalness.

But where do we put them in Blender?

So I’ve dug around and created my own solution and been generally keeping my eye on the scene, and now I’d like to present in this video the best real-time PBR options currently available for Blender and how to use them.

 

LIMITATIONS

Check out the image below, that’s pretty close for blender internal right?! It’s a reasonable approximation surely! The biggest thing missing is the Fresnel – check out how on the UE4 sphere there’s a greater reflection at the glancing angles – that’s Fresnel in action. So in the video we go into why that is and possible solutions.

There’s always room to develop the shader further, so if you do decide to take it further or take it another way, you know i’m interested so keep us posted!
