• 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 Guys!

How do you have to create bump map for FS2020? In FSX and P3D there was a method in photoshop to Red channel to black, blue channel to white, Green and Alpha to emboss the texture in different angles.
Is this the same method for MSFS2020?

Thanks!
 
Hi,

You can use some freeware to create this texture bump very easily : ShaderMap, Materialize or AwesomeBump
 
Thanks a lot! To be honest I do not want to implemet an another external program to my workflow. I liked to create the bump map in photoshop because simply I had more control if I generated it from the texture source psd (I could switch off layers that I did not want to have a bump.) I have created an action so with one click I can generate a bump map from my base material.

I have checked the sample file in the SDK. It seems the structure is different. Red Emboss from right, Green emboss from bottom. But it seems some of the normal maps examples do not have only a white (blank) Blue channel but at some of the smaples have ?ambien occlusion? on their blue channel. The SDK does not mention anyithing about that. Does it have an effect in the game?
It would be actually really nice if we could incorporate ambient occlusion where we do not want to have separate Occlusion Roughness Metallic Texture.

Just a small update. The AO map on the blue channel of the normal map seems to be ignored by the sim. At least for scenery object (Artmodel). Or do I miss here something?

No, you no longer need to switch any channel of a normal map. Depemding on if using a OpenGl or DirectX version, you might have to flipped the Y though.
