this question is not a visual one I have a character- machine designed, made of multiple meshes. I have manipulated the preset skeleton to the humanoid mesh's shape. however when I put the bones in pose mode and select the mesh part I want to weight, then going into weight paint mode with control+tab, the way it is shown in the tutorial I'm following (introduction to blender rigging- blender guru.com) is that the mesh turns to weight paint and the bones to pose so I can attach the bones to the relevant mesh sections. this does not happen. I have tried making the mesh one piece, manually switching modes and various key combinations but regardless when the mesh is in weight mode, the armature remains in object mode please advise

on a side note, i have used this tutorial before with another, simpler mesh and have had no issues so I don't know what has caused this apparently isolated error UPDATE:through sheer luck I found that it works fine if you put bones into pose, select mesh and go into weights. Nothing else, no changes. The bones change to object mode when this happens but once parented they work fine

  • $\begingroup$ have you confirmed that the mesh you are trying to paint is parented to the armature before trying to do this? Select the mesh, and then the armature and Ctrl+P to parent. $\endgroup$ – ohgodzilla Oct 14 '16 at 17:26

I suspect you are trying to assign from Object Mode. Try again from Pose Mode?

First make sure the bones you are wanting to work on are visible and selected in Pose Mode. To make things clearer I usually hide what I am not working on. Select the Mesh Object and then the Armature - still in Pose Mode - and press CTRLP and select Armature deform. Select the Mesh Object and go into Weight Paint....

Parenting

Under the Weight Menu select Assign Automatic from Bones

Weight assign

  • $\begingroup$ Thank you for the help. I have however with further research realised where the issue stems from and have began on rigging. Thanks $\endgroup$ – Cyanidewaffles Oct 15 '16 at 23:35

The answer to this is simple, though I struggled at first with the order. you have to parent the bones to the mesh, select the bones in pose mode, then immediately after click on the parented mesh and enter weight paint mode. this allows for the correct use of the tool when parented
