I am wanting to make a pack of cards in Unity and Maya. I am familiar with UV unwrapping in Maya, but I never used sprite sheet for my models i unwrapped. (They all just fit onto one texture so far).
I learnt somewhere that I shouldn't use two materials on the same object unless I have to (maybe this is incorrect, I don't know, but many of Unity Stanard Assets for example seem to have multiple materials.
In my way of UvMapping, I would need a square source texture which would have both the front and back of the card next to eachother like this:
but my source texture of which i wish to use has all the cards in rows, and the back of the card on its own 5th row:
If I was to use that texture in Unity, and the mesh i have made in Maya, do I even need to UV-Unwrap it? If I do, then how to I make it so that the front and back faces have their own material that I can then set the texture coverage, offset, etc from with Unity (set by the cards suit and face values).
I hope this question makes sense as is, but if I have been unclear and need to explain some part more fully, please let me know.
Many thanks for reading!
