Title: Relief Mapping
Post by: Swifty on January 12, 2018, 01:58:06 am

Thanks to taylor, we've had normal mapping since the Xt builds. Along with it, we've had support for reading height maps for a while but the shaders never did anything with them.

So I'm pleased to finally announce some formal height mapping support in Freespace. I've coded relief mapping which will finally allow our models to have raised/depressed occluding surfaces not part of the mesh.

No test data included but maybe Axem can post the test models he gave me here (Or give me permission to share them)

Does that mean that damage decals can now cause depressions in a target's hull?

m!m's screenspace decals write diffuse and normals into the gBuffer, no height data. Getting the same occlusion effect in there might be a bit trickier so that's something I'd have to get back to you on.

I hereby give Swifty S. Swifterson permission to release the test models. (Note to people checking out the Rahu, that isn't quite the final model yet. I have a few small things to change still!)

Yes! Freaking yes! Finally! I was waiting for this since I bought Substance Painter :D. Great job guys!

Some of my newer models like Anteros or Schrodinger have heightmaps if anyone is looking for some test subjects.

Next up: I hope it will be displacement mapping and tessellation. And real-time environment PBR mapping and lighting.

Anything become of this? There is quite a bunch of ships having Height maps prepared by now...

I've always had heightmaps available but that's just because I've used them to generate dumb normalmaps with a GIMP plugin.

There was some discussion on Discord (#SCP) today.
