I just trying research some feature what i need on my project with MMBAnimation Community. I have tried linking object feature. When i link many object, they are work propely, but when i tried link the character object with rig, i can't go to pose mode to animate the character using rig. I just can move character based object mode like grab (G), rotate (R), scale (S).
So i decided download character pack by vmcomix on blendswap. You can download and use it for FREE. You just need register on blendswap to download it. Let's try the character called Porl from the character pack.
I just trying using character pack, but i still having same problem. The solution from the problem just adding proxy to the character rig. Proxy make duplicate of rig, so you can move character using rig with proxy rig. If you still confuse, let's try this step to practice.
|test render character|
|File > link|
After do that, you can see big guy on workspace. I prefer scale the size first before give proxy rig.
