• 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.

Object illumination in FSX

My terminal has several buildings. All is textured using the same texture sheet, but the parts that are textured using a different part are being illuminated by the sun the wrong way around.

Say a part facing north is lighter due to the sun on face A, then it is dark on face B, with the south side of B being light. How can this happen?
 
You have to flip normal .
Get to your model and choose editable poly and choose on element. Then click on Flip Normal.
This can happen if you choose mirror command from the menu. You have to choose mirror on the modifier tab.
 
Ah OK thanks. I'll try this!:D I just can't understand why it's only happened on the areas where it's using a certain part of my texture sheet.
 
This just turned my object inside out. I can't select a face a flip the normal. It is the "flip normals" in surface properties that you mean?

Also this occurs on different parts of the same object, it's just textured differently.

Okay, what you're describing tells me that somewhere in your project you must have cloned some part(s) of your building and used the "Evil Mirror Tool" button on the top menu...

...that is what is causing your shading problems.

Reselect those cloned/Mirrored polys, then click the "Evil Mirror Tool" again, then immediately add a "Mirror Modifier" to the top of the stack.

Check in the sim again, and if all is well then collapse the stack to e-mesh or e-poly as desired. :D
 
Unfortunately it's not as complicated as that! But thanks for the suggestion. What I had done was remap my terminal with a modified texture, and forgotten to update the bump map! The polys that were illuminating the opposite way were doing so because there was a blank area in the bump map where in the diffuse and illumination maps I had put in some more textures. Silly really.
 
Oh, I see. Not so oddly I've noticed a similar affect should I "forget" to include a bump texture for some part of an aircraft I'm working on... :)
