I need to make a unique index and vertex buffer for all the meshes (primitive for GLTF) inside the model file, in order to batch the drawcalls

The scene graph, from the Node graph, is using the children nodes to build the tree.
At the moment all the functions are recursive, so I need to move in a iterative way.

While the primitive (triangle, quad, colored, etc) manually created working, the GLTF model doesn't.
This let me think to a problem related to the indexes size and the layour memory for the uniform buffer.

in the x86 version, when I create the logical device, during the allocation memory, which happens inside the function VK_AllocationFunction callback, the allocator get a misaligned pointer allocation.
Need further investigation

This need to sort the draw surfaces per material

The descriptor set allocated using vkAllocateDescriptorSets looks leak. Actually I don’t release the descriptor with vkResetDescriptorPool because it looks like fail even if I call at the end of render frame, but I know I have to release in some way.

At moment I'm using the memcpy, the byte per byte copy.
Possible I can add a SS2, SSE4.1 and AVX version to improve the performance

The special key like shifts, controls, arrows, etc are not returned.

Using this with texture load from file or binary does not properly work.
I suspect depends by the staging buffer: the size of the SRC memory could might be greater of the DST memory due the alignment passed in here.

Just the first face is generated correctly, other are black.

The texture map is not correctly mapped onto the model!

This mean to add the "set" keyword in the Uniform structure in the material and group them by:
Set 0: Scene
Set 1: Object
Set 2: Material
(Look at the function Draw in the RenderCore for more details)

The issue could be when loading or when uploading into memory, need investigation!

There are some issues during material set, I have forgotten to use the mask, I need to fix1
