* master:
Fix missing model error in Irr-instancing
closes https://github.com/assimp/assimp/issues/2024: make code more readable.
closes https://github.com/assimp/assimp/issues/2019: fix the qt-viewer without export.
applied coding conventions added check against the known faces
issue_2016 only add material uv mappings if set, ignore when no uvmapping set removed unneccessary pad_i1 field (to prevent unnecessary field read exceptions)
Update XFileParser.cpp
Update XFileParser.cpp
Some FBX files have Null/LimbNode attributes with an empty Properties70 element, where the Element is not NULL, but it's Compound is. The code only checked if the Element itself is NULL, thus causing a DeadlyImportError when trying to instantiate a PropertyTable for an Element that doesn't have a Compound.
fix build for independent build dir
Some review findings.
If someone configures git to always show a commit’s signing information,
this breaks the definition of GitVersion in revision.h:
```
#ifndef ASSIMP_REVISION_H_INC
#define ASSIMP_REVISION_H_INC
#define GitVersion 0xgpg: Signature faite le Fri 15 Jun 2018 20:39:53 CEST
gpg: avec la clef RSA 4AEE18F83AFDEB23
gpg: Impossible de vérifier la signature : Pas de clef publique
878b4b2c
#define GitBranch "master"
#endif // ASSIMP_REVISION_H_INC
```
This can be avoided by passing the `--no-show-signature` to the `git
log` command for retrieving the hash.
