I was about to write a tutorial for Bone Weight Copy plugin for Blender when I discovered that there is a new version of Blender (2.65). Among the new features is "Transfer Weights" which is used for the same purpose. It has also a "Limit Total" option which is used to bypass the "4 bones per vertex limit" (you can choose the number of bones). Here is a little tutorial: ![]() Transfer Weights (B): The tool will appear when you enter in Weight Paint mode (A). It has 3 options (D): -Group: Selects which weights will be transferred. *All: Will transfer all weights. *Active: Will transfer only the active (selected) bone group weights (F). -Method: Selects how will be transferred. You can choose any of them and see the different results. -Replace: Selects what will happen if the model already has weights. *All: All weights will be replaced, the former ones will be erased. *Empty: The vertex groups with weights assigned will remain untouched. For a full transfer of Weights I recommend to select “All”, “Nearest vertex” and “All” respectively. Limit Total (C): The default number of bones per vertex is 4. We don’t need to change it. Keep “All Deform Weights” option unchecked. Transferring: -Import both models. First, the model with the weights you want to transfer (model 1), then the model where you want the weights transferred (model 2). I usually make invisible the bones representation by clicking in the eye icon (E). -Right Click to select model 1. -Shift + Right Click to select model 2. -Click in Transfer Weights (B): You can change the options and see the results in real time. -Click in Limit Total (C): If the message “No vertex group limited” appears, it means that there was no need to use this tool (there wasn’t more than 4 bones in any vertex). You can check the weights by selecting the different bones in “Vertex Groups” panel (F). 24 bones per material limitation: To avoid this error you have to subdivide the mesh: Spoiler: click to toggle -Click in the "+" button to add a new material slot. -Click in "New" -Rename the material. If you want the same material name write "material-0", "material-1", etc. -Enter "Edit Mode", select faces, select a material slot and click in "Assign" Renaming the mesh The name of the mesh will be the name of the .smd file. To change it: Spoiler: click to toggle -Right-Click in the mesh in the right panel. -Click in "Rename" and change the name. Hope this helps. Edited by Segadordelinks, Mar 19 2014, 03:20 AM.

That would certainly come in handy. I'm sure I and many others would appreciate it. |

I know it sucks to keep old versions installed, but you can use the SMD import plugin with the old blender and then save that as a blender-native format, do your bone weight stuff in the new version, then export back using the old one again? |

I tested the smd plugin with the new blender and it works really fine

Yeah, I just tested it, as well, and it seems okay. Not that I really know wtf to do with things once they're imported... That said: Siegfried129, I'd still love a tutorial on weight copying and bone limiting if you feel up to it.

@khaledantar666: When I try to import smd files I've got this error message: (I've downloaded the latest version of smd tools) Spoiler: click to toggle The model appears, but the vertex are screwed up. When there is a vertex for different faces, it creates a vertex for every face. Do you know how to fix it? |

Hi Sega, That is a useful discovery thanks for sharing, I'll certainly try it. Regarding importing smd, I have latest (2.65) version of blender and I am using the same plug-in so I don't know what is causing the problem. Maybe you should try to reinstall blender and then those plug-ins from scratch ? |

Which version of SMD Tools do you use? |

This is the name of file "io_smd_tools-1.5.2.rar" in which both plug-in files were included so I think it is version 1.5.2 |
