Fit to Body is Enabled, but Active Object is Not a Base Mesh

[aberizrihays]

I have clothing and I have my person selected, but I still get this error whenever I try to add clothing/eyes/etc.

I have tried to select vertex groups, I have tried to do this in Edit Mode. Nothing changes.

Can you make a screenshot where the object is selected and these panels are expanded?

Things I would also like to know are:

• Is the "model" panel available and can you change values there?
• Does the same thing happen if you first add a rig ("rigging" -> "add rig")

[aberizrihays]

I hope this is what you are looking for.

I have also lost the "model" and "rigging" panels since I started trying to add skin/clothes.
(Edit: I am still able to change model values in "Shape Keys")
(Edit 2: I was able to create a new human with a rig, delete the new human and reparent the problem child to the rig successfully with appropriate weights. However, I still get errors when trying to apply skin/clothes.)

Did a quick dummy test on a new human, all default settings for the rig. It had no problems adding skin/clothes. .-.

[joepal1976]

It is hard to say what has happened here, but the selected human object is not classified as a base mesh (in the "set object type" panel it is marked as clothes). This might happen if you modify the set of vertices in the mesh, such as adding or removing verts, or using destructive or additive sculpt.

If you wish to try to repair the object, you can attempt to set it back to "Base mesh" in the set object type drop down. But my guess is you will run into additional problems down the line when continuing working on the character.

What you could do is try to set it to "base mesh" and then save it as a new character ("manage save files" -> "new human save file"). If you are able to do that, then the character should be repaired if you open it in a new scene.

I set the object to a "base mesh" and the model panel reappeared. Everything appears to be functioning normally, including loading and unloading clothes, hair, etc.
At first, it would not take a rig with weights, even after a restart. I ended up having to generate the rig so it was the correct size, then unparent and re-parent with automatic weights.
