I have a union in roblox studio and whenever I try and resize it, it gives me this stretched out texture and its a very weird static texture.
This is supposed to be the fabric material. What is this and how can I fix it? It happens whenever I try and resize a small union.
I recommend using the resize models plug-in for this case.

Typically scaling unions with the default tools does not 100% correctly. The plug-in above should solve your problem. Try and apply the texture after the union too.
