Preparing your asset from Mecabricks

Head over to Mecabricks and make yourself an account if you do not already have one.

Find an asset that you like and open it in the online Editor.

Then go to the export menu as follows:

Opening the Export options menu.

A new window will open, make sure to select the Collada .dae format as it includes textures.

Feel free to play around with the Normals and Logo on Studs options. I suggest to disable the logo on studs options as it will introduce extra geometry.

This will give you a file that we can parse in Blender.
