Updates for new FBX version #114

Closed shyam98 closed 4 years ago

This tool is super useful but unfortunately there are some limitations in terms of the output file versions, especially for FBX. There could be a lot more utility if there was a way to use the newer fbx sdk and control the export file version. Let me know you are interested or if I can help in any way!

@Tom-Ski i'm currently checking if fbx-conv still compatible with Blender 2.8 and their new default material (Principled BSDF). It looks fine so far but i had an issue with opacity : opaque materials went fully transparent in G3DJ file. I built fbx-conv locally on linux (thank you for the travis build instructions btw) and it was ok : opacity is 1.0 now. There was a fix merged #94 a long time ago (nov. 2015) but not included in last release (aug. 2015). This plus PR #113 make me feel a new release is needed. Btw, it would be nice to have a versionning (at least tags) in order to know what's in the latest release.

It seems you have trouble configuring build for windows in travis and i guess it blocks a new release. Unfortunately i can't help on Windows stuff.

No pressure, it's just a reminder just in case Blender 2.8 users start to complain and open issues here and there.

Yup, windows is pretty much impossible (on the fbx sdk versions we use). So it has to just be bundled manually which is pretty shit.

I can setup some nodes on jenkins and deploy that way, but it just requires getting round to it.

yeah, opacity is working after you build it on linux. can confirm had a time figuring out the makefile though. here's a couple commands I ran to build it roughly complete/in-order on ubuntu 18:

git clone https://github.com/libgdx/fbx-conv.git
wget http://images.autodesk.com/adsk/files/fbx20142_1_fbxsdk_linux.tar.gz
wget https://github.com/premake/premake-core/releases/download/v5.0.0-alpha14/premake-5.0.0-alpha14-linux.tar.gz
sudo apt install g++
cd fbx-conv/
FBX_SDK_ROOT=<path>
./generate_makefile
cd fbx-conv/build/gmake/ && make -f fbx-conv.make
LD_LIBRARY_PATH=FBX_SDK_ROOT/<path to so>
fbx-conv/build/gmake/bin/Debug/fbx-conv file.fbx output_file.g3dj

This is what is used for travis that works https://github.com/libgdx/fbx-conv/blob/master/.travis.yml
