No. Previous versions are not compatible with 2.80. The only way to do this would be to export to some other format that supports all the features you need and then import to a previous version. In vast majority of cases you will run into problems when attempting this so this is not a very good idea. It's best to choose a version and stick with it from the ...

It seems it is dropped officially. Personally, I still use it because sometimes that's the only format I can get models I need in, but while it's inconvenient, it is still possible to import 3ds to Blender 2.79 and copying models from 2.79 to 2.8 is no problem. As for exporting,...
The normals on your mesh are inverted. The effect you're seeing is caused by backface culling in the game engine, where faces with normals pointing in the opposite direction of the camera aren't rendered.
In order to fix this, you can try to recalculate the normals to face outside by using Mesh > Normals > Recalculate Outside or Shift + N. If they are ...
Blender's node system cannot be exported since the 3D formats aren't able to store them and the game engines do not have nodes that are equivalent to the ones found in Blender.
What you need to do is bake your textures. Generally for game models you start with a high poly, detailed model from which you create the low poly version that can be used by the ...
The .stl exporter already has the option Selection Only to export the selected objects. In Blender 2.80 the exporter options can be found in the lower left area of the file browser. In Blender 2.81 you may need to click on the cogwheel icon to show the options.
Blender 2.81 and later
In my case the following method helped:
Note: They only started supporting alembic files in both unity and blender in the recent months. Blender needs to be 2.81 and unity needs to be 2019.3.0a6 or higher and also have the alembic package installed in unity. Mine didn't work until I restarted my computer also.
Second note: ...
I am using a great tiny add-on called "Create Bounding Box" by Shane Ambler
script link. It adds a bounding-box around the selected object.
Just install the add-on script by going to edit menu > preferences and install. The add-on is also compatible with Blender 2.80
For anyone looking for a Blender 2.8 version of @CoDEmanX's answer
def clamp(x, minimum, maximum):
return max(minimum, min(x, maximum))
def camera_view_bounds_2d(scene, cam_ob, me_ob):
Returns camera space bounding box of mesh object.
Negative 'z' value means the point is behind the camera.
