• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

Hello,
So with the new update of Prepar3D, the PBR support is added. I have a few questions about it. All answers are highly appreciated.
1. How is this going to affect the market?
2. Will people be still interested in the older sceneries with the fake reflection maps?
3. Will the support for Dynamic Reflections be the same as it always was?
4. Are there any tutorials, on how to convert pbr textures to be used in the sim. (Preferably MCX)?
6. Will there be any tutorials on how to get started with PBR and modelling specifically for a flight sim (If it’s different)?

Thanks for reading. I’ve also heard, that you have to re-do all the textures.... How come? I am in the middle of making textures for my scenery, and I don’t want to waste any time. Why aren’t the old textures fine?

Best regards,
AidasP
 
I am also curious about PBR, but I think the answers to those questions may become clear as we get more experience on the subject, hopefully in the following weeks.

I myself will do the first experiment with 4.4 this weekend.
But supposedly current sceneries are not to be affected by the new PBR support implemented, their appearance and behavior shall remain unchanged.

My additional question is if the PBR scenery objects/building will be noticeably different for normal user, from within the aircraft cockpit, from a distance I mean.

Clearly from close range it is noticeable, see:
 
Hello...

As sunayk stated, since the SDK v4.4 was just released (approximately 72 hours ago - as of this writing), many of us, haven't had the time to install or update. Most likely over this weekend, alot will come to light. There is some information concerning the PBR Materials within the Learning Center though:

https://www.prepar3d.com/SDKv4/LearningCenter.php (under the Modeling tab -> PBR Materials)

To get more information on what PBRs are and what they can do, there is a 3 part "tutorial" on the subject:

you can find out in DCS, it the best simulation game that maximize the PBR at the moment
see post #135 for some screen capture

from my opinion, applying PBR for scenery (airport) isn't give big difference, it more important to be use in aircraft, for realistic model and texture

4. Are there any tutorials, on how to convert pbr textures to be used in the sim. (Preferably MCX)?
6. Will there be any tutorials on how to get started with PBR and modelling specifically for a flight sim (If it’s different)?

P3D v4.4 Documentation cover PBR material, even though it not as detail as FSX material Documentation. but painting software such as Substance painter and Quixel, use this PBR for painting, more easier for developer to create more realistic texture
