This is an animated seagull. THE ANIMATION IS PRE-BAKED!
If you want to fumble with the rigging or re-animate it then you have to do it in Lightwave or you just re-rig the whole thing in your favorite package
The animation was done in Lightwave and exported to Blender using ALEMBIC
The ALEMBIC format is versatile, loads into every package: Maya, Max, Houdini, C4D etc...
2K Textures. Hand painted. COLOR and ALPHA
The ALPHA texture is used for soft feathers and it gives a more artistic effect. This bird is not PBR
Use it in visualization, far/medium shots but don't use it in close-ups.
The best approach is to load the Blender file and see what it does. There are no complicated solutions, hidden traps etc. Very straightforward setup.
Loading the Alembic into any application should work.
