Hoping someone can help, I have a vest that I have Modified. (One of the unlocked Rockstar ones) to make in to a Police Vest. 

 

However when I go in game I get some shuddering from the mesh.... I am using Blender and Sollumnz to modify and export the mest... I am fairly new to modding Ped's and this is my first real attempt at something bigger than retexturing... 

 

This mesh is one piece, its a single mesh that's been extruded and manipulated, not 2 mesh's joined together... (that was my first attempt and the shuddering was much worse)... I am assuming its the weight paint thats the issue?

 

I do have Zmod and a licence so I can use that to fix it, just not sure how... any advice is appreciated.. thank you.

I guess the vest is conflicting with clothes that are beneath it.

maybe make the vest bigger or remove the tshirt … Just a guess

Thanks, will try that
