Load 3d files with Qt3D

Hi i’ve build Qt3D for my Qt version (4.7.4 mingW), and i succefull compiled my small app. Now i want to load my 3D files, but the only file format i can load is .3ds For every other file formats like .blend, .obj, or .smd and maybe other file formats it give me error like : “Asset importer error: Failed to open file” for obj files “Asset importer error: Failed to open SMD/VTA” file for smd files “Asset importer error: BLEND” for blend file why it do this, ive tried to use assetviwer example it can also load only 3ds format.. There is a solution?? Thanks in advance!!
