How to import 3D objects


You go to a website that offers free 3D objects, for example https://sketchfab.com/ or https://www.turbosquid.com/ or https://archive3d.net/ or https://3dsky.org/ or http://www.cadnav.com/

Look for some, for example here I searched for a hat.


Download the 3D object to your PC. Often websites offer several formats. Preferably choose the Collada format (with the .dae extension), or alternatively the Wavefront Object format (with the .obj extension).

If the object is not offered in either of these two formats, you can convert it for example :


On Planet, click OBJECT > NEW



Type an object name, go to the TOOLS tab and click on IMPORT .dae/.obj.

you may have an error message when importing, often because the object has too many triangles or that the terrain where you are importing has no more space.



And here's your hat !
All you have to do is apply a texture and resize it with STRETCH option 3d.

If your object consists of several volumes, you should link it first (mode LINK, option LINK ALL VOLUMES) in order to be able to resize all the parts at the same time.

If you have applied a texture and your object still remains in one color, it is because it did not contain any uv information to stretch the texture. You can then use Planet's UV_MAPPING mode to create uvs.

How to reduce the number of triangles of an object in blender

To delete a part of an object, left-click on it and it will be surrounded by a yellow line.
Press the Delete key and you're done.

If you want to reduce the number of triangles in a part, here's how to do it:

1) click on the wrench on the right


2) pull down the "add modifier" menu

3) click on "Decimate

4) At the bottom, "Face Count" indicates the number of polygons in the object (see green arrow).
By dragging the "Factor" slider (see red arrow) with the mouse, you can reduce the number of polygons: the image of the object will change, as will the "Face Count" value. When you're satisfied with the result, press Ctrl+A to Apply.

Finally, one last tip: to see the object's textures in color, click on this icon in the top right-hand corner.
