IdTech 4 PBR shader?

[TeaMonster]

You guys may remember Blackrayne Studios from quite a few years ago. He's just announced that he's working on a PBR shader for IdTech 4 (Doom 3/Prey/Q4).

Not sure how advanced it is or if it's usable yet. I didn't see any announcements here so I thought I'd let you guys know.

From his post on Duke4.net ( )

"Interaction Shader for Quake 4/Doom3/Prey and CG source along with batch files(you need Nvidia CG to compile the shaders to interaction.vfp).
https://github.com/j...l23/idtech4_pbr "

By the looks of things, he hasn't adjusted any of the existing maps to use the shader properly.
It would be a nice addition to D3/Q4/Prey if he completes it.
