Wow, this goes beyond me
flip3d, you've asked that exact same question directly or indirectly 6 times so far by my count, and you keep getting the same answer:
If you modify the physics, export it as an AV, and then upload that AV to swaps, it is
your work and is acceptable to upload.
What part don't you understand?
If however, you download (or, ahem, "otherwise obtain") an EA or kex, and modify the physics, then post it as an EA without the original creator's permission, you have gotten out of line.
Phrank, you beat me to it on that one. That was out of line to post Inky's SR-71, and the "note" flip3d inserted at the end of the description proves he did NOT have Inky's permission to post it. (If he did, it couldn't have been "brought to his attention" that it was Inky's - he'd already have known) And giving credit "after the fact" doesn't make it right.
flip, you should keep posting the question until someone finally gives you the answer you want! Whatever answer that may be, I really don't have a clue
what you're wanting to hear...
