Starting out in Blender

.blend - native Blender format. You can open it with menu File -> Open. Also, Blender can import .dae, .fbx, .abc, .obj and other (menu File -> Import). Some of additional import/export plugins you can enable in Edit -> Preferences -> Add-ons (for Blender version 2.8+).

Hi there, have you checked the file version so far?

So, first you unzip the package, then what do you get? Can you send a screenshot of the unzipped folder?

Taking a screenshot depends on your operating system.

on Mac os:
you need to hold shift + command + 3

On windows 10:
you should just push the print scrn button
On windows 7:
again use print scrn to take the screenshot, then open up paint and push ctrl + v to paste it, then save the image.

After you've taken the screenshot you can easily drag and drop it in this conversation.

It seems like it doesn't work here in the forum talk. So, the best way would be to follow my instructions. Do you see a .blend file in the folder of the model?

Perhaps you would be better downloading the fbx (if there is one) and then importing it into Blender as the version shouldn't matter then.

I agree with SimonTGriffiths, still if you're blender is the latest version, you shouldn't have any issues opening the .blend file.

Thanks for the suggestion SimonTGriffiths I will try it.

In blender I recommend .fbx as a non native archive, this is a format i use on it as well as rhinoceros, 3dmax.
