When i weightpaint in Motion Studio i usually set a pose. Then i bend my character to have a look at the deformations. Let's say the left knee. I can even weightpaint in this pose. When done i set my pose back and go on with another part of the mesh.

Since i was told that i better not set the default pose before i am finished with the rig (i still may need to adjust some joints while weight painting. That's the step to check if the joints are at the correct position, and if they have the needed freedom), which means i don't have a pose in which i can reset my mesh, how is it though to work here? How do i weightpaint the new bones?

Well what I do is set the default pose as shown in the vid - once this is done I don't really need to go back to it that often.

Next I set up a short animation sequence - sometimes using .BVH sometimes not. Just a second or 2 will do as long as it covers a good range of movements. As I scrub through the animation any mis-weighted vertices show up pretty quickly so I active the weight painting tool at that frame and adjust the weights there - no need to return to the default pose to do this although I usually can if I want to.


Hope this helps.

Ah, so you need the default pose for weightpainting. Thanks :)

But i may still need to do adjustments at my joints. Which can conflict with the Default pose as shown. I can just hope that my joints setup is correct. This is something that i usually check while weightpainting. :rolleyes:

Okay, let's touch the evil button. I will find out early enough if my joints fit :p

Well the default pose is not strictly necessary for weightpainting but obviously can be very helpful.


The biggest problem I have is remembering to remove SDS before adjusting vertex weights.:o


I've also had some success by setting joint limits before I attach anything to the skeleton by simply setting limits that look relatively normal for the movement range I'm after. Putting it another way - I use the character mesh as a reference and set as many of the skeleton characteristics as I can before attaching the mesh.


Here's another short video showing some of my workflow.
