Re: A PBR upgrade for the P3Dv4 C172
Hi Nick.
I take it then, that we can no longer have a polished metallic paint effect, unless we use the old NON-PBR model?
Thanks.
Steve.

By the way. Just for comparison. This is what I get using PTA v2.67.
The PBR model.
and the NON-PBR model.
Same time, same day and same location. I personally prefer the PBR version.

Re: A PBR upgrade for the P3Dv4 C172
That is a good question. I would like to know what format the dds is too. It looks likea DXT1 type to me, with no Alpha channel.
Also, by experimenting, the DXT5 and 888-8 format seems to work as well. Would there be any long term side effect to using the no-loss 888-8 format?

With red channel in metallic texture you can control if the surface is metal or non-metal. If you set the channel to white then surface is pure metal (black - dielectrics/non metal), with albedo you can control the brightness/colour of the metallic surface to your taste, with roughness (metallic texture alpha) the smoothness of the surface (black - rough, white - polished). There is no reflection mask or specular map anymore, the smoothness of the surface is controlled by roughness - metallic texture alpha channel.bladerunner900 wrote: ↑17 Dec 2019, 17:28 I take it then, that we can no longer have a polished metallic paint effect, unless we use the old NON-PBR model?
For metallic effect you have to copy c172_metallic.dds texture to your livery folder and edit it's metallic channel (red), than tweak albedo color and metallic alpha channel to your liking.
I recommend checking material section in Learning Center.chm in Prepar3D v4 root directory.

Well. Here's my second attempt. The first was a black version of this but I see the logic now and will refine it further, for just the spinner for instance.
Once more, thank you Michal. I can't wait for the Spitfire to go PBR.

Sure. Here you go.

For now, I think I have followed the A2A protocol. As in, the c172_albedo.dds is DXT1 with mipmaps and the c172_metallic.dds is DXT5, also with mipmaps.
No doubt the c172_albedo.dds could be given a slight blue tint

I'm giving up painting and taking up brain surgery. It's simpler.

I hear you. I can't see me doing this very often. Probably just to update the ones I have already done. When the time is right.Ron Attwood wrote: ↑20 Dec 2019, 11:13 I'm giving up painting and taking up brain surgery. It's simpler.
