Can't second this. I dare say FreeBSD's ports tree covers ~98% of Linux' third party software. I may be wrong, but I don't miss anything.
There may be some few very special packages only available under Linux, and for sure there is the one or other user insisting on a certain package, not (yet) available here. But that's rather an exception.
For what may be missing here there is either an alternative (not seldom even better - you just didn't knew it yet; give it a shot. being always open for alternatives should be common when using alternative OSs anyway), or it's not really a loss (IMO), or it will be ported to FreeBSD sooner or later (maybe, you do it one day.

)
Personally I never missed anything under FreeBSD (Well, games. But they are not crucial. Since I switched to FreeBSD for me it's less gaming, more production. Just a change of what I was used to before, and not to the worse.

)
After all, what's the use in having all software packages as bleeding edge versions, when the whole shit does not work reliably because of a giant not conformable update mess and dependency hell?
Why not just simply do a
pkg install blender?
(You probably missed that section in
The Handbook? Well, coming from Linux you are experienced to not having an useful documentation. But here is unix ground.



The
FAQs are also really worth to skim, cover a lot of typical newbie questions.)

Once you get used to the changes you will admit: good choice.
