• 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.

How to add Satellite Background Image on Blender 2.8?

Hi,

I wanted to add Satellite Background Image for scenery development using EMPTY > BACKGROUND IMAGE. I tried the method stated here but Blender 2.8 doesn't have the Dimensions tab.

How can we do this for Blender 2.8?
 
After abandoning the old background feature in 2.8 there seems to be no way to set the dimensions of background images directly, at least with the latest release. As a workaround I create a plane of the desired dimensions and set the cursor to one of the vertices. Then I add an image empty, snap one corner to the cursor and resize the background image via 'image size' (x dimension) to match the dimensions of the plane. Unfortunately, you can blow it up only to 1000 meters, so I scale the image up to, say, 100 percent first and set the size to x/100 (if the imagery is smaller than x = 100 kms). After that the plane can be deleted. Of course, that only works if the image already has the correct aspect ratio - otherwise you have to fine-tune the scaling manually. But maybe there is a more 'elegant' and exact way. As far as I see all other current solutions only work in render mode or - in case of simple textured planes - are useless when in wireframe mode.

It mainly talks about Blender 2.79. I need solution for Blender 2.8.
 
Ok - lets try again.

In 2.8 the scale is set to metric by default. Which is the best for dealing with measuring anyway in MHO.

1.with your UI empty (youve deleted the default cube)
2. selct the Z view using the BLUE Z orientation top right (your looking down)
3.drag the image you want to use as the background in to the centre of the UI screen.
4. The scaling screen will open on the UI right side.
5. look at the SCALE OBJECT it will read x 1.000 , y 1.000, z 1.000 - its the 3rd set of controllable sectors in that area (location and rotation are above it

This is the OBJECT scaling you need to change the background size REMEMBER the scale is NOT Blender units as previous version but in metric 1 metre

Note that the tab your in has a ORANGE square in the icon area left of the scalable UI.
To change the measurement default to imperial (feet and inches) look 2 icons above for the cone and circle icon and click in there and select units, in there youll have the option of metric or imperial

hope thats what you'r looking for to change the size of the background image??

Here's another solution for 2.8 to keep control over the placement and the dimensions of a background image exact to a centimetre without the need of scale factors:
  • Add an image as background (empty).
  • Apply it's width x 2 (size entry of the empty - in pixels or centimetres, doesn't matter as long as the value doesn't exceed a value of 1,000).
  • Add a plane of the size of your background image (same units as applied to the empty - scale to 1,1,1 afterwards, of course)
  • Make the plane the parent of the empty.
  • Apply the final exact dimensions to the plane in its dimensions box. The background image will scale up accordingly.
  • Hide the parent plane in the viewport.
Linking the background image to a mesh object wasn't possible in 2.79.
