I've just finished doing some animations for my model for my Unity game and I noticed that on the top, it sort of collapses on itself (see screenshot provided) and I'm not sure why it's doing this.
I had a look around and everyone talks about how the model's clothes clip through the body but not the clothes itself.
The top only has 1 layer, it's not a box shape but I believe I have used one of the modifiers to change the thickness of the material(I was following an online tutorial but removed the cloth simulation due to it causing more errors then it was worth but even after removing the cloth simulation, the material kept the same thickness)
If screenshots could be included with any helpful advice, it would be greatly appreciated as I still consider myself a novice when it comes to blender :)
Also please note that due to this model appearing in an upcoming game, I cannot share or upload the model, sorry.
