Im trying to make a texture for this helmet. But Ive unwrapped the helmet and in texture paint it just paints all over the helmet when im only painting in one spot.
How can i fix this?
Welcome

…to tell you how to fix your setup we first have to know what exactly you have done, because obviously something is wrong 
.
So: because this “painting” seems to paint in triangles… you are not in vertex paint mode ? And
the UV’s do not overlap ?
You also showed only a clipped part so we do not see any settings in the full window.
( Please do not show in 3000x2000 , because one have to do more work than if you use a smaller window and one could see this directly in the forum.)
So make it easy to help you
