You and the OP don't have the same web address. Am I the only one noticing it?
Also, I should think any site without the "S" on its url http isn't secured and looks phishing.
The TOR link is the TOR web address from the official Bitblender site. Check it out at least.
I think some need to inform the bitblender about this mistake and I will advice the OP to make use of bitblendervrfkzr.onion with the exclusion of the http.
When you visit the site, you'll see that it hyperlinked to bitblender....onion without the http one, if that really worries you.
