Big skin deformations

kabazu

Let's see if someone can help me, I am making a character, and I was making a larger version with transform constrains, I have managed to resize and reposition the skeleton depending on which skin is selected, but when adding one of the images of the large version of the character, they look deformed, they inherit the transformations I've done to the bones, is there any way to avoid this?

Am I correct in assuming that your rig is using the skin constraints only for changing the position of the bones? I have tried that way myself before, but I found it quite hard to rig.

I've seen a user on Twitter making body shape controllers:

It's probably easier to control the body shape change by using the scale like this.

This is just my guess, but the rig is like the attached Spine project.

If you are okay with such a simple rig, you might want to make it like this one.

I hope this will help you.

the problem is that I want to use different images for each skeleton size, this way I stretch the pieces of the small model to make them big :think:

In that case, I think you can use the mesh binding in animate mode and skins together, while using the body shape change by scaling. If you have never done mesh binding in animated mode, please refer this blog post: Blog: Mesh binding tutorial

Set the skin constraint (Skins - Spine User Guide: Skin constraints) so that the transform constraints are not used for the normal size skin, but only for the big size skin, and then bind the mesh of the big size character images to the scaled up bones in animate mode. The result will look like the attached Spine project.

Though the character images for the example project are too simple that it may be difficult to see the difference, if you check the images folder, you can see that the original image size is different for each skin. They are bound to the scaled bone without stretching thanks to mesh binding in animate mode.

Chiming in to add that you can use the constraints to resize the bones while the images are bound to the root, then after doing that, you bind them to the correct bones so they don't stretch.

I did the same in this stream:
