Re: [Bf-committers] Proposal: Building blender using docker.io
Hi, I don't have strong opinion about having some container-based approach next to our current build process if it's maintained and used by reasonable amount of users. But i'm against making it officially suggested way to have blender compiled locally. `this is because using blender on a real hardware and system is what you really want as an artist. It is also more convenient for development. If there are difficulties with making blender compiled on a real system this is either to be addressed via documentation (HowTo Compile section in Wiki) or adopt current install_deps script. And one more thing -- we should not bump requirement to an external libraries and just break compilation with older versions. Such actions will piss everyone off regardless how they're building blender. Blender should be kept compilable with reasonably older version of libraries comparing to what we're using for official release (disabling some features at build time is acceptable for this). P.S. We can also share official release environment as a chroot or virtual machine image for those who wants to create truly static builds.

Re: [Bf-committers] GSOC 2015 Project Idea - OpenGEX Importer
Well, someone made an exporter and is keeping it up to date.. Which is not so much the case with Collada..

I don't agree that including every standard is going to solve the problem. Wouldn't a student's time be better served fixing the errors in the collada importer since it's an already established albeit complicated standard? On Fri, Feb 13, 2015 at 2:01 PM, Jonathan Railsback jonbit...@hotmail.com wrote: Everyone - How about an OpenGEX Python Importer Plugin for Blender? I've been doing some work with the Blender COLLADA importer, and something with a simpler, more coherent spec (such as OpenGEX) could help Blender attract more users in game development area. I was trying to use Blender to customize models from popular asset stores (Unity, Turbosquid) but was always hampered by the fact that nothing ever worked quite well. The Autodesk FBX-COLLADA converter has issues, and other tools I found exported animation using a non-matrix format (rot-X,rot-Y,rot-Z,scale, and translation) that didn't work well with Blender unless you implemented annoying work-arounds (which I'll be glad to share if anyone cares!). For whatever its worth, I've read the COLLADA spec and the OpenGEX spec as well, and OpenGEX is at least a lot more compact so it must be easier to understand :) I've been pondering working on such a thing myself, but I suspect a student working on it full-time over the summer will make more progress than I can in a few evenings here and there. Eric Lengyel, author of the OpenGEX spec, created it to support his game engine, and has written exporters for Maya, Max, and Blender to allow models to be imported into his engine. I guess the idea here is that an importer would help support cross-tool content pipelines in the game development area, since the export plugins for Autodesk tools already exist. I suspect I wasn't the only one on Earth that has tried to edit models but got stuck by the mess that is COLLADA and the non-GPL-friendly blackbox which is FBX. I did some Googling, and I think someone has already written a python library to parse OpenDDL (the text-based language used by OpenGEX) so I dont think it would be a totally ground-up effort.
