You can use -fno-exceptions or by defining the symbol JSON_NOEXCEPTION and TINYGLTF_NOEXCEPTION to fully remove C++ exception codes when compiling TinyGLTF. hpp is working well, but is overkill for TinyGLTF and tiny glTF header-only library headers. org/tinygltf. Describe the issue When create GLTF file for the scene with lights, actual reference to the light does not assigned to the node. In our usage scenario we would like to write images to separate files as they are shared between multiple scenes, but at the same time to be able to output the scene to a custom stream. target = TINYGLTF_TARGET_ELEMENT_ARRAY_BUFFER; // The vertices take up 36 bytes (3 vertices * 3 floating points * 4 bytes) // at position 8 in the buffer Search wiki. Otherwise, it is free to a If load file in Windows system, and the filename contain WideChar character, tinygltf can't open it. glb file through a call of the TinyGLTF::LoadBinaryFromMemory will most likely crash, which could result in an Denial Of Service. Implement glTF loading. Thanks a lot, @syoyo and @Ybalrid!!It would be great to see the tinygltf viewer animation branch merged soon!! Btw, are you aware of any (open source) skeletal animation editor (apart from Blender) in which for example you could load mocap files, set/tune the "resting" skeleton pose, blend animations, retarget them, etc? For future reference: A little late on this one, but here's a way to access data from buffers when querying. This library is included in the project SDK.
