Hey Benjamin! Beat me to it, haha. 😀
For your suggestion, that would ultimately fall on whatever Sketchfab allows, however it would likely be totally doable. I’m not entirely sure how they do transparency, (might be worth a look at their documentation!). You would create a UV Map for your pine needle plane so all of your planes use the same texture, likely with a transparent background, which Sketchfab would use in its engine. From there, I believe they allow you to check on “double sided” for your shader, which would allow you to see both sides of the leaves.
Really, besides the UV unwrapping, the rest would likely be done in an image editor and Sketchfab itself, but I hope that helps give you some guidance!
