Blender is a 3D creation tool that professionals and hobbyists alike use for all kinds of projects.
Second Life, on the other hand, is a virtual reality, a metaverse (lowercase m), that one could describe as the Internet in 3D. In fact, I find myself using the term “flat Internet” to refer to the normal Internet these days.
If you are one of the many Blender fans, you probably should grab yourself a Second Life account to live as and with your creations on the platform. What else you can do is to sell your creations to other users who LOVE buying 3D objects and gadgets to enhance their 3D lifestyle.
I have a pack of Second Life objects imported for Blender, if you’re interested. They help you in scaling stuff for Second Life 1:1 scale. They are the same as ZEN METAL Systematic SL package. (Both are 1 Linden, so you can gift them, too without forcing the receiver to pick them up themselves.)
