New parts added are always a great idea in itself, but a rather complex task to pull off; Scrubs has to model each individual part on his own, in his free time, and as precisely as possible while still making it low-res enough to work for an online service mostly used by low-performing hardware.
Therefore, if you have a look at the "Missing Parts" forum entry here, you will quickly see that it's quite a long list. Furthermore, Hero Factory/Bionicle consists of (aside of constraction) mostly decorational parts, which usually have no further purpose and/or usage (by TLG, there are some incredible creative MOCs with Hero Factory/Bionicle parts of course), and the are old as well as disused, therefore they aren't top priority.

So, I would love to see Hero Factory/Bionicle parts here as well, but they are hard to produce and unlikely to be used often, so therefore they are unlikely to be seen here any time soon.

Very true, and well said. Scrubs is just one guy, and very talented might I add (seriously puts LDD to shame). At least there's people here that can compensate for that with bricks. 😄

I would also like to see Hero Factory parts, though to me it's mostly about the constraction parts such as used for the mech's from Invasion From Below

I think NGCHunter2 is mistaken about usability. IRL if used bionicle feet, chest plates and poldrins as heads. weapons as claws or wings. i remixed them into beasts, robots, and star ships. just because parts r ment to be decoration dose not make them unusable as anything else. and why not start a patrion? u get enough people to pledge then this can be more than a free time thing and become a full time then.maybe even make enough to higher more modelers. or even just reach out to volintear modelers.

I think you misunderstood me; I clearly said that "Furthermore, Hero Factory/Bionicle consists of (aside of constraction) mostly decorational parts, which usually have no further purpose and/or usage (by TLG, there are some incredible creative MOCs with Hero Factory/Bionicle parts of course)". TLG doesn't use them too often, of course they can be and are used wildly in MOCs, but there are a ton of other parts that are high priority because they are still used by TLG as of today or are newly added.
Also, Scrubs has a Patreon already (https://www.patreon.com/mecabricks), which sadly doesn't make enough money/month that Scrubs could afford doing Mecabricks full-time or even hiring other modelers (though it has to be said that Scrubs puts quite his whole free time into Mecabricks already, though modeling parts isn't the only thing that has to be considered when maintaining it).

what about reaching out to volentears? also what about promoting the patrion of youtube n social sights?

i too agree we need bionicle on mecabricks
