Hello, I'm new to Blender, but I know most of the basics of creating some things. So I'm trying to make a rigged mesh avatar, and I have come across this issue again and again. I know about the mirror modifier, and I do apply it. But as for that, that's just it. I upload as a .colldae file, and I get this as the result. What step did I miss tahat I can connect the mirror mesh to its twin and upload it as a whole? My second question revolves around the invisible giant that appears whenever I try to upload the workbench female model. I tried re-edting the female to match the idea avi I had in mind, but every time I upload to see the preview, I see an new female body mesh that I have never seen before. Can anyone explain what's going on, and how I get rid of the larger body?

I'm sure there may be a thread or two about this, and if so, please do share the links? All help is welcomed. Lately, I have been attempting to create tattoo or marking for meshes yet of course the normal tattoo only is applied to the default body. I know I need the UV mapping, which for the mesh I'm working with, I have, but how do I actually apply another layer without replacing the first? And what format would the said marking have to be in?
