Re: [Assimp-discussions] Error loading file: (assimp:) std::bad_alloc - When loading a complex model

[kim k. <kim...@go...>]

Hi,

could you send us some information about the model size and your system? I
am a little bit concernet about our memory consumptions and it would be
interesing to see how its scales with bigger models.

Thanks a lot,
Kimmi
