I have a rather silly question that, i'm 90% sure, has already been answered here but i cannot find a way to word a search to get the right result. So sorry for that.
I like the default UV Grid texture that blender generates but in some cases,(like with low resolution images) the grid's tiles are way bigger than most of the poly i have on my model so it's not really useful to spot the stretching.
So i was wondering if there is a way to make the tiles smaller without having to manually import my own UV grid? (it's easy to work around but i'd like using the shortcut rapidly from blender's UI) Thanks
