I get extreme amounts of downloads on my scenes for some reason, i suggest you use logos and more interesting thumbnails. (placing the logo of the manufacturer above the gun) I can even do logos for you if you want.
To hide all the spam, i went into settings and disabled ''default'' and ''Marble & Athlons BFDI''. Then place your scenes in technical and just forget that the spammers ever existed.
I wasn't lying, the 2 scenes this user posted are useless because they are just re-uploads! This is what you're doing, you should know! They are identical to loads of other scenes with the same thing going for them, it indeed is immature and lazy to post something that's been done thousands of times before.
Don't get me wrong, i mostly blame Algoryx for making the simulator free to immature and lazy people.
I'll never like Algodoo in it's current state. Too bad the creator jumped off his own train. If there was a version of Algodoo in the future that would be more ergonomic and less crashy than the current one, i'd consider using it over Phun, but this will likely not happen. Building deformable stuff, which is pretty much the only thing i do and have ever done, is much easier and less problematic in Phun compared to Algodoo.
You are asking this question to mostly people who have never used Phun, there isn't even a link to Phun on this website (It's phunland.com/download) , this question could be asked 5 years ago but now? I'm the only Phun user left.
Tutorial of my old way of building cars:

Building a realistic structure car like this one is just not a good idea unless you have built deformable stuff for a long time. I'm really into cars and how they're built, how their safety-cages and crumple-zones work. It's too hard to explain how i built this, i don't have names for many of the methods, you will just have to pick it apart and look at how it's built.
