• 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.

EDIT: Always the same with me ^^ I post exactly 1 minute too early. Searching an hour for the problem, then i write here and 1 min later i find the problem. :-)

Can be ignored, i found the issue (hidden objects that interfered).



Hi again.

I followed the great Tutorial from Bill, basically through the end, what worked pretty well and i didnt have any issues following the steps. I could bake AO also and it looked great.

Now i tried to make the same AO bake out of my own buildings, wich is not that much different than the Portland FireDep. Infact its a bit easier even. The problem is that i get black parts in the bake and i have no idea why. You can see on the pictures, the windows and garage doors are fully black.

All steps are as far i can see the same as Bill did it. So i made this:

- model the building without the windows and garage doors cut
- made the unwrap to a colortile image
- cut the garage and doors
- extrude it inwards
- bake the AO

And i get this:

Tried all kinds of things already but it stays black.

Would be great if someone could help :) Thanks.

Are you sure you have a light source in your scene? If I am not mistaken, you either need to have a light source in the scene itself or your environment needs to be configured to become the light source. Otherwise there is nothing to bake for the renderer.
 
Actually he only needs a light source within the rendering/ enviroment, not necessarily within the scene or project. If using an enviroment light which enviroment scene is he using?

It also could be that the rendering/ bake isn't setup strong enough
 
Thanks everyone :) I forgot to delete the 2 layers that ive hidden That were the cutter objects for the windows and garage doors. Seems they interfere with the baking somehow. As soon i deleted them i could bake as usual.
Not sure about the lightsource, usually i put in a HDRI and a image-plane used as ground. That seems to give me good results. Probably the HDRI acts as kind of a lightsource.

Anyway, in this problem it was indeed the 2 hidden layers though.

Thanks again still, every input is always appreciated!
 
Yes, the HDRI acts as the light source within the rendering tab/ baking. Depending on which HDRI you use can change the look of the baking also.
