Hi, Can somebody please figure out vertex normals. They should be byte. But not sure. They are in 3848536924.VertexBuffer.

It's the last thing i need to finish my 010 Editor template exporter.

Here is info:

612424467.VertexBuffer
Vertices
Offset > 0x1C, Stride > 12, Vertex count > 7412 Data Type > Float

3848536924.VertexBuffer
Normals, UV, etc
Offset > 0x1C, Stride > 20, Vertex count > 7412

2139299717.IndexBuffer
Indices
Offset > 0xF5DC4, Index Count > 4320, Data type > uint16

Thanks in advance.

EDiT: Tried this one but it doesn't yield nothing good

byte bx = Var0, by = Var1, bz = Var2;
double length = Math.Sqrt((bx * bx) + (by * by) + (bz * bz));
double dx = bx / length, dy = by / length, dz = bz / length;

EDiT: I got some clues but not sure how they are converted. There is some unknown after x,y,z. maybe it's somehow involved in conversion.

I can see some patern in it.

did you get the normals? what formula did you use to get the final coordinates?

in the end, I did it, thanks to everyone who posted on this topic.
