@anponteg // Unfortunately no. But UPBGE is the latest version of Blender after all, so you can just use it to whatever you want to do with Blender.

Is it possible to have upbge-git installed without conflicting with blender?

It looks like the build is failing again with the Embree patch. I'll try to fix it soon.

EDIT: Now it's done :)

Just updated it to make it compatible with the current master branch of UPBGE. Please let me know if it doesn't work.

Please update the PKGBUILD to make it similar to blender-2.8-git and fix python version.
