PBR or Standard materials ?

[Dakanok]

Hi,

We are developing an archviz application with Babylon. So, obviously, we are looking for the most realistic render.

In the archviz world (outside babylon), PBR is currently the way to go, so we plan to create PBR materials.

But what is the babylon roadmap regarding this? Is it just a (really cool) feature added without further development, or a real direction took by the development team ?

What about performance ? Are the PBR materials using more resources than Standards ?

Thanks for your expertise.

Hi, 

PBR are already in the core : http://doc.babylonjs.com/overviews/physically_based_rendering and http://doc.babylonjs.com/overviews/physically_based_rendering_master

Resource-wise, I don't know... But I guess it depends on your mesh and your textures

[Dakanok]

Thanks Temechon for your answer.

I know PBR are already implanted. We are using it.

My question is : will PBR materials still be maintained in the future of Babylon, or is it better to stick to Standard materials ?

About performance, let's say we are using the same mesh and the same texture with Standard and PBR material...

Obviously they will. Both will be but as we also want to provide more realistic rendering we will invest more on the PBR.

Using the same mesh and same texture (like in diffuse and albedo), the PBR will be slightly slower because involved equations are more accurate and thus more expensive.

Thanks Deltakosh for your reassuring answer about the future of PBR in Babylon.

Just a last question: with PBR materials, at your knowledge, is there any incompatibility with some graphic cards ?

[GameMonetize]

nope  this is the job of Babylon.js to ensure that it works everywhere so we've got you covered

[Dakanok]

Cool, thanks.
