Welcome.
I have a problem with adding rigging to my model, mayby because i’m not good at this. I added rigging to it but I have a problem with rear legs of it when i trying to make sitting or lying pisition - possible by bad weight pait. The model was created for 3d printing not for animation - I wanted to add rigging to simplyfy changing poses and didn’t ended very well. I’m looking out for someone who would help me fix it, because I know that I’m not good in it. I’m also not perfect in moddeling but I beggining cathing it.
