• 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 Gauge brightness at night

Hi, I've made a $vc gauge sheet for this panel. I'm trying to get it to light up at night, so for the emissive texture I have it set the same as the diffuse. My issue is that the whole panel is "lit up" at night. (naturally this is expected since the whole panel face is mapped as opposed to seperate faces for each button etc.) Is there a way where I can manipulate the texture sheet to have for example only the buttons or text light up and not the whole face of the panel?

Use a night texture instead. The night texture belongs in the plane's texture folder not in the plane's panel folder.

hi again tom!

I have tried that, but I don't seem to be getting any results. I'm not sure if its because of me using .dds or .bmp or the alphas (orientations?), but it appears as if there is no emissive textures at all

First of all, if for some reason the link kindly provide by Tom, I attached the PFD file. From what I am seeing, you probably need to take a closer look to the file -by the way, nicely written by Fr. Bill Leaming-.
At first glance, make sure you have two textures properly assigned to the specific material used in all your "planar" polygons: One named $Vc as DDS with No Alpha channel (DXT1 to DXT5 file extentions; if I can recall for FSX and P2D) and other one named (for example) Vc_L (same deal).

I hope this make sense to you and good luck!
