It is unclear if content licensed CC BY 3.0 can be upgraded to CC BY 4.0. However - strangely - it is clear that:
CC BY 3.0 licensed content can be laterally upgraded to CC BY-SA 3.0 content, and
CC BY 4.0 licensed content can be laterally upgraded to CC BY-SA 4.0 content, and
CC BY-SA 3.0 licensed content can be vertically upgraded to CC BY-SA 4.0 content.
If anyone can link to information that difinitively confirms or refutes the upgradability of CC BY version 3.0 to version 4.0 please share here. Until then, a couple possible solutions to the above-listed scenario:
Combine both of the above example works that are under CC BY 3.0 and CC BY 4.0 into a collection under the single license CC BY-SA 4.0. This does not necessarily change the license of any other assets in your project. Only the derivatives of the two sets of assets would become CC BY-SA 4.0, not the code nor any other assets licensed in separate collections.
As you said, keep the two assets separate, not derived into new works, but use game engine wizardry to "combine" them on the fly on-screen. It is true that the combination of individual assets by the game code does not generally constitute a new derivative since the assets remain separate in their "natural" inactive state. However, this seems cumbersome to me. There is no moral issue here in my opinion, it just seems like it would be a lot of extra work who's only advantage is avoiding CC BY-SA components in the project (e.g. solution #1). All projects are unique and have their own unique requirements, so if this is your preferred solution, go for it! :)
Ah, yes. ANY ONE of the three, not all three at once. Though please do list all 3 licenses in your credits so other people know they also have that same choice.
@slade_38012: If you don't understand GPL, I recommend choosing one of the other two licenses. Namely, CC-BY 4.0, which is easier to understand, IMHO.

Under the terms of CC-BY 4.0 you are indeed allowed to modify the image and use it in your game/youtube-video/t-shirt printing business/whatever, commercially or non-commercially, so long as you give proper credit to SCay. Check out the FAQ for one good way to give credit: https://opengameart.org/content/faq#q-how-to-credit. For instance, add the following text to your credits page or credits screen:
ok, cool. Thanks for the clarification.
Sounds good... but, what album art are you referring to? Is there album art embedded in the flp files?

Groovy. Thanks.
Where is the vector image from?
Nice. How was the tree made? It looks like a familiar technique.
