Extraction of models with uv from Intel GPA

GPA-Mesh

Attaching UV to models extracted from GPA

This is a very tiny cmd tool. extract UV information from VBV(Vertex buffer vector) csv file to insert into the .obj model.

Use:

1. Extract a single model

gmesh -s TEXCOORD1 D:/my_buffer.csv D:/my_mesh.obj D:/out_mesh.obj

command :-s [texcoord column name] [vbv.csv path] [mesh.obj path] [output path]

• texcoord column name (specific name for UV in VBV)
• vbv.csv path (It should be the vertex buffer vector(VBV) file '.csv' exported from GPA)
• mesh.obj path (It should be the mesh file (.obj) exported from GPA)

2. Extract multiple models

gmesh -m TEXCOORD1 D:/mesh_and_vbv

command : -m [texcoord column name] [mesh and vbv files folder]

• mesh.obj and vbv.csv files folder (the mesh file and vbv file name must be the same, e.g. ground.obj & ground.csv)

Limitation

• Currently, only models with a StartIndexLocation of 0 in the GPA DrawCall message Execution Arguments are supported, and support for StartIndexLocation will be added later.

• As the Obj file can only store one layer of UV, if need UV2 information (such as LightmapUV), can export two obj models with UV1 information and UV2 information respectively, and use the copy uv function in the free software 'blender' to merge uv1 and uv2 together
