FGBlenderTools - FlightGear Development Tools (Blender)

[ctesc356]

Hello,
a concrete application...
VNLK, the famous airport of Lukla in Nepal.
With its 12% sloping runway, the generation in ws2 is unrealistic and ugly.


We tried to improve the scene with an ac patch on the existing terrain.

The ability to enhance the 3d landscape that FGBlenderTools offers makes it possible to get something that comes close to reality.


Playing a little with the regionalized textures makes it almost perfect.


Ok, we are far from automatic generation, but for specific adaptations, which some sites deserve and on reduced perimeters, it is an interesting tool.

We lack the possibility to intervene on airports generated by genapts, it would be an alternative to WED which is very heavy and exclusively 2d.
xDraconian has promised to look into it...

A work in progress: the Alpe d'Huez Altiport (LFHU) with its 15% slope.

@ctesc356,

Those results look great!

I've got my computer in a bit of a mess right now. Installed a new OS and time is going into getting everything functional once more. Just yesterday I was able to compile the Blender dependencies, so I should have Blender operational soon.

I've begun to work on importing the airport BTG files while loading the tile terrain.

Work Items:

Import tiles into separate collections - done
Import the airport terrain while loading the terrain tile - In progress
Support for loading multiple tiles and aligning them appropriately - not started
Experiment with multiple Scenes - not started
- Airport loaded with their associated objects to allow positioning
- Main Scene containing terrain only
- Airport Scene containing airport terrain and objects
- Object Scene containing only a single object

Hello,
I wanted to test your work.

Under Mint 19.1, Blender 2.83.3 installed by downloading "blender-2.83.3-linux64.tar.xz" from "www.blender.org" I can't install "pyshp" and "pyproj".
If someone has a solution...

As to work with "fg_btg_io.py" these libs are not essential I did without.

To get a compliant situation, I installed Mint 20 and Blender 2.82 by the package manager.
"pyshp" and "pyproj" are installed.
But... mint 20 comes with python3.8 and apparently FgBlenderTools is not compatible?

What can I do about it?

[xDraconian]

@ctesc356,

It works with Python3.8 just fine.

Blender utilizes the Python installed within its installation folder. I assume you have a path similar to blender/2.83/python/bin.
Check to see if this python/bin folder contains pip or pip3.8.
install pyproj via:

Code: Select all

pip install -U pyproj

or

Code: Select all

python3 -m pip install -U pyproj

If you are missing pip then review the FGBlenderTools readme file. There are instructions for downloading pip.

[ctesc356]

Hello,
thank you for your help. I finally managed to install "pyproj" and "pyshp" with the damn "pip".

To install in blender's python 3.7.4:

Code: Select all

./python3.7m -m pip install -U pyproj

./python3.7m -m pip install -U pyshp

into ".../2.83/python/bin."

The test:

Verify pyproj Installation within Blender
Open Blender's internal Python Console
import pyproj; pyproj.test()

doesn't work, but it's well installed in ".../2.83/python/lib/python3.7/site-packages".

PYTHON INTERACTIVE CONSOLE displays:

>>> import pyproj; pyproj.test()

Traceback (most recent call last):
File "<blender_console>", line 1, in <module>
AttributeError: module 'pyproj' has no attribute 'test'

[xDraconian]

That appears to a success. Don't worry about the pyproj.test() failing. They may have removed that within pyproj. As long as you are seeing the modules within site_packages it should work.

Hello,
Testing your improvements:
- when loading a "btg" the mesh does not turn to "global"position in blender
I uncommented the lines :

Code: Select all

# rotate bucket into viewing position
        if bucket_num != -1:           
            bl_obj.rotation_mode = 'ZYX'
            bl_obj.rotation_euler = rot_euler


.
of "fg_btg_io.py" and it does.

- The recording (SAVE btg) doesn't work. I added the following lines at the beginning from ""fg_btg_io.py":

Code: Select all

from .btg_bounding_sphere_chunk import bounding_sphere_chunk
from .btg_vertex_chunk import vertex_chunk
from .btg_normal_chunk import normal_chunk
from .btg_uv_chunk import uv_chunk
from .btg_property_chunk import property_chunk
from .btg_geometry_chunk import geometry_chunk


it seems to work.

If there's anything I can do to move forward, let me know.

Did Zac´s problem get resolved? I am seeing the same on my Windows laptop with Blender2.83, but not with my desktop running Blender 2.82.
BTW blender 2.90.1 is out now. Dare I upgrade?
Alan

Edit:
P.S. I still have Blender 2.82 on my laptop, and it works OK with that.

[Alant]

Furher tests.
Blender 2.9 has the problem that Zac reported.
Another problem with Blender 2.83 is that the textures are not loaded when the .blend file produced by FG dev tools is loaded. The model is grey.
The same -blend file (produced by Blender 2.82) loads correctly in Blender 2.81, Blender 2.82 and Blender 2.9.
I have been testing using the 707.ac file in fgaddon.

I have not tested this hypothesis, but the problem may lay in the new versions of pyshp/pyproj, and not with the Blender version.

Mageia 8/54, Blender2.83.
I installed FGBlenderTools_v0.4.1. The "3D View" addon is installed and enabled, the "Import / Export AC3D FG" addon reports an error:

File"/usr/share/blender/2.83./scripts/modules/addon_utils_py",line351 in enable mod=_import_(module_name)
File $home/username/.config/blender/2.83/scripts/addons/io_scene_flightgear_import/_init_py",line 25, in <module>
from bpy. types import Operator, INFO_MT_file_import, INFO_MT_export
ImportError: cannot import name 'INFO_MT_file_import' from 'bpy.types' (unknown location)

where am I making mistake?
tks

[Zdenal]

sorry,
Mageia 8/64, python 2.7.18

I'm here again. I advanced the installation of FGBlenderTools. An error is reported when Blender starts :

File "/usr/share/blender/2.83/scripts/modules/addon_utils.py", line 351, in enable
mod = __import__(module_name)
File "/home/zdenda8/.config/blender/2.83/scripts/addons/io_scene_flightgear/__init__.py", line 63, in <module>
from . import fg_shapefile_io
File "/home/zdenda8/.config/blender/2.83/scripts/addons/io_scene_flightgear/fg_shapefile_io.py", line 35, in <module>
import shapefile

and FGBlenderTools are not available.

When I comment out line 35 in the fg_shapefile_io.py file: "import shapefile", FGBlenderTools are available, but only for .ac files. .btg files cannot be loaded.

Thank you for your help in finding the shapefile module

[Zdenal]

And again: after installing "pyshp" and marking the files to load (in Blender):

Info: STG import time: 0.0005 seconds
Error: /usr/share/games/flightgear/Scenery/Terrain/e000n40/e007n43/3072361.btg: Unsupported BTG version: 6
Info: BTG import time: 0.0010 seconds
Error: /usr/share/games/flightgear/Scenery/Terrain/e000n40/e007n43/3072361.btg: Unsupported BTG version: 6


Am I getting closer to my goal?
