Hey guys! I've found this universal FLVER importer plugin for Blender on GitHub. (all credit goes to elizagamedev)

But it cannot open most FLVER character files. I forked it, and made some fixes on my own, however without the knowledge on how to properly debug a blender python plugin, I can't figure out how to fully fix it. Currently it throws an exception when retrieving weights. (Index out of range, in importer.py, line 164, it's got something to do with bmesh) When not importing the skeleton, it imports the mesh now without any errors, but the mesh looks pretty rough. (Looks like it's flat shaded)

If you have any insight, and could help me out, feel free to contribute.

• 0. Open the exe. (Yes this has a very basic GUI)
• 0a. Optional: select a save location.
• 1. Select the .flver file you want to convert. Once you browse the file, it will convert immediately.
• 2. Use the Bloodborne tool (all credit goes to daemon1) to get correct bones, and copy them from that ascii to the ascii you got from this. (Replace the 0 at the beginning with the bones from the other (Bloodborne tool converted) ascii -- select everything from the beginning upto the same number you see under the 0)
• 3. Use XNALaraMesh.2.0.2 BLENDER plugin to open the ascii, make sure "Join MeshParts" is disabled. Noesis is NOT recommended, since most hair/fur have 3 UVs -- Noesis only exports 2 at most. (At least into FBX)
• 4. Have fun.

Code: Select all

for vert in bm.verts:
                weights = inflated_mesh.vertices.bone_weights[vert.index]
                indices = inflated_mesh.vertices.bone_indices[vert.index]
                for index, weight in zip(indices, weights):
                    if weight == 0.0:
                        continue
                    vert[weight_layer][index] = weight;print(weight)

Thus it displayed the weights of c2310.flver for me. If you print out vert.index you might get more clues.
(But without the sample flver in question it's hard to judge.)

if self.data_type == self.DataType.BYTE4C:
            weights = struct.unpack_from("BBBB", buf, offset)
            return tuple(weight / 32767.0 for weight in weights)

You're in _unpack() of flver.py, aren't you?

Why do you inserted
weights = struct.unpack_from("BBBB", buf, offset)
for .BYTE4C and not for .BONE_WEIGHTS?

So something like (... ... 1.0 1.0) is no weights, probably. Unless you're using a wrong divider. Additionally divided by 2 you'd get (... ... 0.5 0.5)

else if (member.Type == LayoutType.Byte4C)
                        {
                            for (int i = 0; i < 4; i++)
                                BoneWeights[i] = br.ReadByte() / 255f;
                        }

weights = struct.unpack_from("BBBB", buf, offset)

if self.data_type == self.DataType.BYTE4C:
            weights = struct.unpack_from("BBBB", buf, offset)
            return tuple(weight / 255.0 for weight in weights)

            weights = struct.unpack_from("BBBB", buf, offset)
            return tuple(weight / 255.0 for weight in weights)

(in flver.py) with c00_000_00.flver (Bloodborne)
I get this error:

Thank you, I wish the same to you! Thanks for all the help too!!
