Re: Physically-Based Rendering Builds
I tested out this latest PBR build, and it looks fine. Though any issues on team glowmaps have yet to be reported, glowmaps are no longer being applied for no reason.

By the way, will this AO maps work well with heightmaps? I think so, but all we need right now is the height map support. Kobrar has written some custom shaders, so you may want to look into it before integrating it, along with new effects such as self shadowing in normal and height maps. It also makes the model gloss/reflectance more accurate and physically.

Re: Physically-Based Rendering Builds
A black and white AO map should work out of the box. I assume red, green, and blue channels are sharing the same values. So in that case, ambient and cavity, taken from the red and the green channels, will have apply the same amount of darkening on ambient, diffuse, and specular lighting.

well, actually, i am talking about about images with only a grey channel, not quite sure if we are talking about the same thing right now - if you handle those like you just described, than everything is fine

Re: Physically-Based Rendering Builds
Oh, I get what you're saying. I think if this texture only has one channel, OpenGL will just place that channel into the red while setting the rest of the channels to 1.0. So your map will only affect ambient occlusion and not cavity occlusion. So, yes, it'll still work out of the box just a bit more work is needed if you decide you want your map to affect diffuse and specular lighting and not just ambient lighting.

Re: Physically-Based Rendering Builds
Will ambient lighting affect normal/parallax/displacement mapping? I've heard that recent game engines of this generation, such as CryEngine and Unreal Engine 4, support this.

tested it, seems like it is so, which is a waste of memory actually, if you want to have both being the same, like i do

a suggestion: LODs 2 and 3 don't use specularity, thus they are more or less unlit models, it would make sense to use the unlit map for them, right now, they are totally black for a ship with high metal amount

Re: Physically-Based Rendering Builds
Here's the result of the ambient occlusion test of this PBR build. It's a recently released Raguel, with an AO and unlit maps applied.



However, I don't know how to create reflectance/gloss maps using GIMP, which is used as my primary image/texture manipulation program.

Re: Physically-Based Rendering Builds
That's because trying to make PBR reflectance and specular maps by hand is damn near impossible. Look into getting either substance painter or Quixel Suite.

Re: Physically-Based Rendering Builds
As someone who primarily uses Linux now, both Quixel Suite (which requires Photoshop) and Substance Painter are not natively available on my platform. In addition, both products cost more than I'm willing to pay for modding and content creation.

I'm not that good at modelling and texturing, either.

On the other hand, I've heard that AwesomeBump, and a special branch of Blender now support PBR.

Re: Physically-Based Rendering Builds
If modellers can't make good use of PBR without expensive proprietary software I think that's seriously at odds with FSO's ethos.

AwesomeBump sounds like it will suffice. As for the PBR viewport in Blender, Cycles itself is a PBR engine, it is capable of exporting PBR textures, it's just difficult to get them to look correctly in FSO due to the differences in calibration, that feature just allows the view-port to use PBR in real-time as well.

It is possible to make PBR textures using GIMP, you just have to know your way around the mask system very well. It also requires knowledge on the sRGB values of the material(metal, plastic, etc.) you want to use.

Re: Physically-Based Rendering Builds
I tried using AwesomeBump, but... when I tried opening textures larger than 2048x2048, not only it hang, but also causes my AMD laptop display driver to stop working, only to be recovered instantly.

As I say, I prefer using GIMP for texture manipulation, for the time being. I intend to use it for creating PBR assets.

Re: Physically-Based Rendering Builds
Hey, Swifty. I've got a problem here. It seems that the PBR build has encountered an access violation when turning on the ship thrusters in the Ship Lab while viewing the PBR-enabled ships such as my Raguel. Then, my AMD laptop display driver amdkmdap stopped responding and successfully recovered.

Checking with the debug build, this problem doesn't happen. I think it's due to the driver. Regardless of that, optimizations and preventive measures must be implemented.

Re: Physically-Based Rendering Builds
Updating the display drivers to the very latest version should solve that problem. Lacking that, filing a feedback is appropriate, given that Windows 10 has a feedback app that allows suggestions and problems be reported, and Microsoft takes these to improve it.

I am a Windows insider since November last year, and I'm not the only one. Looking into the "Display Drivers" subsection of the Hardware section, there are many people complaining about display drivers stopped working, even on Insider builds.

So... did updating your drivers fix the problem, or not?

Are... are you asking that FSO somehow update your drivers for you?

Re: Physically-Based Rendering Builds
Me. Generally, I agree that changing settings via the AMD Radeon settings could be a workaround, until at least it's fixed in newer builds.
