Set specific format as primary file - IRR for example

[GitHubDragonFly]

Hi Viktor.

Just to ask if your code could be adjusted to deal with a specific format as a primary format?

For example, IRR files appear to be a scene that can contain other file formats (like X or IRRMESH) and this PR in the ASSIMP repository shows what an IRR scene would look like.

As per the mentioned example, if I try to use my viewer with it then it's a hit and miss of which file format is to be treated as primary, the following are the examples:

• scenegraphAnimMod.irr file all by itself will show the shapes from the scene
• scenegraphAnimMod.irr + dwarf.x files will show the dwarf
• scenegraphAnimMod.irr + cellar.irrmesh files will show the cellar
• scenegraphAnimMod.irr + dwarf.x + cellar.irrmesh files will show the cellar
• scenegraphAnimMod.irr + dwarf.x + cellar.irrmesh + textures will show textured cellar

This seems to have alphabetical approach and only 1 importer is ever used - tested with the following slightly renamed files:

• 1scenegraphAnimMod.irr + 2cellar.irrmesh + 3dwarf.x files will show the shapes from the scene

I don't really expect any solution for this, just curious if there is any possible way to actually have it working properly.

I will close this topic but if anyone ever comes up with some solution then do reply here.
