• 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.

P3D v4 PBR (Normal Map) Moire Noise Issue

Hi All,

My PBR assets appear to have deformation in P3D V4. They appear to show a moire effect from the normal maps - and I was hoping someone may have a fix for this?

The effect appears to be worse on corrugated metal type materials - and looks worse from a distance, see below:

Note: I only get this issue in P3D V4 not in V5

Any support is greatly apreciated!

Hello...

how were the Normal/Bump maps created? It would be easier to know what the normal maps look like prior to converting them to DDS.
 
Hi,

Normal Maps were made using substance painter,

An example is the below:


Find it strange that V5 can render it completely fine, yet V4 applies this effect,

Apreciate your time

Within Substance painter was it Directx or OpenGL? I believe that is the latter one.
 
Correct - Was open GL, However the export preset utilises the converted maps in the correct channels
 
OpenGL isn't correct for P3D though. DirectX is. How do you have Substance Painter placing in the correct channels.

Red in Alpha anything else?
 
I use the following export preset, with the converted (Direct X Normal Map):

OK... what does the Blue channel look like afterwards?
 
Hope this helps:




I am unsure what the issue is, but plenty of my other PBR textures work fine with the same preset? - and V5 also is okay, so seems odd

In most cases,... the blue channel should appear white (nothing appears to be there when going through either ImageTool or one of the DDS plugins)... Red should be solid black after the fact.
 
From Image tool:

RED Channel;
red-png.59456


Blue Channel:
blue.PNG


As per SDK the blue channel represents the blue channel from the Normal map - so not sure what the issue would be here?

Right-click on the Red channel in the presets. What does it show? along with the other channels?

Red Channel: "Default Black"
Green Channel: "Normal DirectX (Green)"
Blue Channel: "Normal DirectX (Blue)"
Alpha Channel: "Normal DirectX (Red)"
 
Hmmm....

Have you tried placing this normal map through Image tool or Photoshop dds plugin or GIMP dds plugin? How was it saved into a dds file?
 
ahhhhh... OK... MCX doesn't convert properly especially when an alpha channel is present... also,... may not have converted it to a DXT5 but a DXT1
 
OK... It does seem strange but that what I have noticed with MCX sometimes it does alright and then other times not... Have you tried putting through ImageTool? I mean in converting into a DDS
