Export from Blender to Unity

Introduction

In this artiĀ­cle we are going to see how to export 3D modĀ­els, with mateĀ­riĀ­als, UV maps and aniĀ­maĀ­tions, from Blender to the UniĀ­ty engine, in which forĀ­mat and a some useĀ­ful tips to preĀ­pare modĀ­els before exporting.

How to export a 3D model?

The process is simĀ­ple, being in object mode, we select the 3D modĀ­el or modĀ­els that we want to export. Then click on File > Export and choose the forĀ­mat to which you want to export it.

In my case I always check the "SelectĀ­ed Only" box to export only the selectĀ­ed 3D modĀ­els to Unity.

Format to use

The forĀ­mat I use is .fbx (FilmĀ­box), which has not givĀ­en me any inconĀ­veĀ­nience and allows me to export the mateĀ­riĀ­als conĀ­tained in the 3D modĀ­el, the aniĀ­maĀ­tion skeleĀ­tons, the actions defined with the Action EdiĀ­tor and the Shape Keys. 

Things I take into account before exporting

Before exportĀ­ing from Blender to UniĀ­ty I try to improve cerĀ­tain aspects of the 3D modĀ­el in order to have everyĀ­thing as orgaĀ­nized and simĀ­ple as possible.

About the names of the 3D models

In Blender's OutĀ­linĀ­er we can modĀ­iĀ­fy the names of objects and since those names are going to be exportĀ­ed directĀ­ly from Blender to UniĀ­ty, I like them to be as descripĀ­tive as possible.

In the long run, when we have many 3D modĀ­els in our project, orgaĀ­niĀ­zaĀ­tion is fundamental.

About the origins of 3D models

The oriĀ­gin of an object is the point in the space that repĀ­reĀ­sents it. The transĀ­forĀ­maĀ­tions of transĀ­laĀ­tion, rotaĀ­tion and scale of the object will be applied with respect to that point. So, in genĀ­erĀ­al, we are interĀ­estĀ­ed in its being in a coherĀ­ent place in the 3D model.

The Blender 3D CurĀ­sor is used to change the posiĀ­tion of the origin. 

We enter the geomĀ­eĀ­try editĀ­ing mode and select a verĀ­tex, edge or face where we want to place the oriĀ­gin. Then press "CTRL + SHIFT + S" and choose the option "CurĀ­sor to SelectĀ­ed", to move the 3D curĀ­sor to the selectĀ­ed element.

Go back to Object mode, right click on the 3D modĀ­el, go to the "Set OriĀ­gin" option and choose "OriĀ­gin to 3D CurĀ­sor". This will place the coorĀ­diĀ­nate oriĀ­gin of the 3D modĀ­el in the posiĀ­tion where the curĀ­sor is.
