What is PBR

[xDeadlYx]

I have a Question, in Update 18.10.5 they said (Rhino Prime’s Iron Skin has received the PBR treatment! This also allows Iron Skin to reflect your chosen energy color. (Default is still gold!)).

So what exactly does that mean ?

PBR = Physical Based Rendering.

[AEP8FlyBoy]

PBR or Physically Based Rendering is a rendering technique used to give materials on textures light diffusion parameters based on the type of material. Increasing graphical quality without impeding performance on a large scale.

Metal shines differently than Cloth which shines differently than Dirt and so on.

Basically, it looks better, and we can now color Iron Skin so... yeah, both good things. ^-^

That your iron skin on rhino prime is now the same color as your energy.

Means you can now change the color of the gold bits on the Prime Warframe/Weapons basically.

to expand a bit - the big important part about this Rendering technique, is that unlike traditional rending, Physical Rendering allows an object to be comprised of a (theoretically infinite) number of materials, every little section can look like it's made out of literally anything that you want it to look like it's made out of.

this is a huge step up from traditional rendering where even if say, a character is wearing cloth clothing, with amor plates on it, and exposed flesh, the entire character would need to technically be rendered as one material.
which means that to get things to not look ridiculous, rendering settings would be adjusted so the skin looks like skin and cloth looks okay, but that would leave the metal to look nothing like metal.

note that this mostly affects lighting, reflective calculations in general. but that's very important, as lighting and reflections is what most of the detail you see in the real world comes from.
so getting this stuff right makes things look a lot more 'real'. or it has the capability to that is, you have full control over how it looks through rendering settings.

here's an example comparison:

 

and here's an Article explaining the general premise behind Physical Rendering.

Too bad it wrecked Rhino's Iron Skin with the Default Prime Skin eh?
