• 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.

Hi all,

I am struggling to get my head around creating comp textures for MSFS using photoshop using the RGB channels for AO,Roughness,Metalness.

Does anyone know of a tutorial document or video? All the PBR videos I have found so far do not seem to fit what I need.

thanks
Stinger
 
Hello...

Where specifically have you looked or having difficulty? All PBR components (AO, Roughness, Metalness) are the same. The only difference is where and how they are placed within the COMP, It appears you have the information on what component goes where.

If it is "how" to place them in there proper channels within the COMP with Photoshop, then I can suggest a tutorial. "PS: Creating AO" for photoshop within the Resources area at this site. The only problem with it is the placement of the different maps in their proper channel (such as Prepar3D v4.5 through v5.1 compared to MSFS), but the "how" is the same.

In a nutshell, you create each of your three comp layers in a separate greyscale psd file, and then you go from here:

Mode should be RGB. Make sure to assign your greyscale images to the output channels in the correct order.

I wrote down these steps. I'm a newbie and I think this is right:) Correct me if I'm missing something.

How to create PBR Comp file in Photoshop for Blender

- if you have your AO, Roughness, Metalness each in a layer in photoshop......
- save each image into separate .psd files ( AO, Roughness, Metalness)
one at a time, select image and make it the only layer visible, then -> file->scripts->export layers to file
make sure "visible layers only" is checked, name and save (if you don't make sure "visible layers only" is checked, it will output
all your layers and if you have a lot, it will be a mess!
- you should have 3 .psd files for AO, Roughness, Metalness
- open all 3 files in photoshop as separate images
- change all to grayscale image->mode->grayscale
- also flatten the 3 images if not already (important) Layer->Flatten Image
- click on channels to view channels
- in the dropdown select merge channels (should be to the right of
the channels menu (four lines)
- run through the process and select the AO for the first channel, then Roughness and
Metalness
- Finally change to RGB image->mode->rgb color
- save as a .png file with the name "name_COMP.png" with name being whatever you want to
call it.
 
If you install ImageMagick you can even make this a one-liner on the command line:
Bash: 
convert ao.png metal.png rough.png -combine comp.png

I use this a lot for textures from texture.com oder cc0textures.
 
I agree, @sleepy_t, ImageMagick makes this dead easy. In your example, though, I think you may have metal and rough reversed. The correct order is R=ao, G=rough, B=metal. I think that IM reads the input files in RGB order by default.

Does this work for making straight Photoshop comp files without blender? My metal textures turn white at night and I can not find the cause. The look amazing during the daylight. I am using RGB 8 bit and export to DTX5 DDS. My metalness and roughness are in their correct channels.

You are mixing them up :)

You can do your stuff in Blender, AND PLEASE BAKE TEXTURES else small airfields are huge in size, then you combined the texture as shown above in Photoshop or Gimp, finally you can open them in Blender and export.
