Use Eevee When Creating Materials For Video Games If you are assigning the texture in Blender, you should be able to preview the result before you export and make changes to your UV map where needed. The UV map needs to be well structured to prevent artifacts on the textures when imported to the game engine. Most of these will also require textures and as a result, may also require a UV map.Ī UV map is a 3D object that is cut apart and mapped out onto a 2D image editor, as a means of being able to more easily map a texture from a png or jpg onto the 3D model. Do You Have A Suitable UV Map For Your Objects?Īll solid objects that you will use as potential assets in games will require the use of materials, which can be created either in Blender or in Unity. This won’t move the object meshes, only the origin points get placed back to the center, which can make things simpler in Unity. In this case, you can apply all the transforms of your meshes so that they all have the location value 0,0,0.
If those objects are static meshes used as part of the scenes environment, then you may not be planning on using those objects in another capacity and may want them in Unity exactly as they are in Blender. The process for applying the rotation and scale of the objects is the same, but you would instead select all the objects together and then apply their transforms all at once rather than selecting each object one at a time. If there are multiple objects in your scene you can export them all in a single FBX file. What If You Are Going To Export An Entire Scene Of Static Objects? The rotation values of the applied object should now read as 0,0,0 and the scale values should read as 1,1,1 in your side panel, but the appearance of your model should be exactly the same as it was before you applied it. Select the option labeled ‘Rotation and Scale’ to apply each of these transforms.
To fix this, use the hotkey combination of ‘Control + A’ to bring up the apply menu with the object selected in object mode, you will see a list of transforms that you can apply. If any of these options are not set to the default values then this will alter the way the model looks when brought into Unity. While not as important, keep the location set to 0,0,0 as well and have the geometry close to its origin point. If you look at your object transforms in the side panel, you should see the rotation value set to 0 on all three axes, and the scale values all set to one. The most common issues that can occur are incorrect rotation and scale of the object, which are normally the result of not applying the transforms in Blender. Applying The Rotation And Scale Of The Model Before is a short but important checklist of what we need to do before we begin the process of exporting. If you are exporting a game model for the first time or are just not sure about the process, then we recommend starting off exporting objects to a test project before moving onto the real thing. What To Do Before You Export Your Game Model? Let’s dive into more detail in how the export process works and what to do if we find any issues.īy the way, if you want to learn more about the different file formats that you can use for exporting assets, check out our article here. These issues are normally a result of errors made in Blender either with the object itself or the chosen export parameters. There are many issues that can occur when exporting a model, or collection of models, from one application to another. Then go to Unity and you will see your FBX file in the project folder.
Set the asset folder of your Unity project as the destination for the export and click the export button.
In the file browser that pops up set your parameters so that +Y is up and +Z is forward, then define if you want to export parameters, materials etc. To export as an FBX from Blender, 1st select the objects that you want to export, then go to File > Export > FBX. So how do you export a 3D model as an FBX from Blender to use in your Unity game project?

This also means that you have to know how to transfer data from one application to another. If you are in the field of game design either as part of a company or as an independent developer then you will likely need to use multiple applications to create the assets for your game or project.
