contains 587 points for each uv, pos, normal, as well as 1310 indexes of the Triangle_Strip (format, ps2 always have grids in this form)
Model in attachment in gltf format (all data in the Traviso.bin binary file as float, in order of position, normals, texture coordinates, then uint32_t indices). I chose this format because it is simple (too lazy to study fbx, sdk is not very clear, but what I want is ideal) and its description is textual (in my favorite json), and the data is in binary form that is ready to be loaded into the video card. I know about collage, but this format is entirely textual, based on xml I don't like and is outdated.
The Delta Morph PLG chunk contains 12 facial states

For several days now I have been puzzling over how to correlate deltas and grid vertices. Although the section with data on points has 1 more set of indices for the mesh (with which it did not work to build a mesh), but it is one for the entire mesh, and the set of indices I used is considered an optimized set. It is unlikely to be useful, besides, it has 954 face 3 indexes + material index, and the set of points to which the indexes are applied is the same. I think deltas should be applied to grid points and has nothing to do with indices. And the data0 field should contain the point numbers.
