I wasn't sure if there was an FAQ on this or whether the hero converter has any support now whatsoever, but it appears the darkspore hero converter isn't working, like, at all. The PNG created appears to be either a really strange Maldri model or a completely bugged model. Every fixed PNG looks identical
(I'll upload it in a reply to this post shortly)and doesn't work when moving into the game. My spore client follows the installation order recommended on the site and is a disc installation patched up to the latest patch prior to the new Origin update.
The converter has been placed in a folder named DarksporeConverter on my desktop and is running as administrator. I have renamed all of the hero PNGs to the hero's name in lowercase; e.g. "wraith.png".
This is the original Seraph-XS .png, named "seraph.png"

This is the converted Seraph .png
EDIT: I also tried converting a spore creation I found on the Sporepedia. Here's the PNG;

It came out the exact same as before.If anyone else who has the converter working could try that original PNG and see if it converts, please let me know!
