Hello! This is going to be my second question thread. I have started blendering around last week and I am trying my best to improve. Actually I have made some cool static meshes and scripted them inworld like into a hoverboard. Anyway, I seemed to be doing ok with static meshes. However, I have recently bought an avatar called "Kemono". This avatar is popular these days. Most clothing and attachments don't tend to fit on these avatars unless they are specificly made or are modifyable ( and you know how to do it). The marketplace has tons of clothing and such, however I wanted to go ahead and make myself a chest armor piece just to learn rigging. The creator of "Kemono" avatars has provided a download file of the avatar mesh dummy here : https://utilizator404.wordpress.com/downloads/ So I downloaded it, opened the one that is for default blender and not avastar. Then I created a very simple chest armor piece. When it was done, I started looking for rigging tutorials. I eventually came across this video : https://www.youtube.com/watch?v=EI0bujHVMPM After following this video, I uploaded the mesh. Now my problem starts here, when I turn "Skin Weights" preview on, parts of the mesh go invisible. Like so: Now, what happens when the mesh is uploaded is it seems fine untill I wear it. When worn, most parts of it go transparent and you can see through it. Anyway, sorry for the long explanation but I wanted to show my problem clearly. Any help would be appreciated. Thank you! :] Here is the error in all its full size glory:
