Creating an FBX model in Blender involves both preparing your 3D model and then exporting it in the FBX file format. Here's a breakdown of the process:
1. Model Creation in Blender:
Design your 3D model:
Use Blender's modeling tools to create your desired 3D object. This includes creating the geometry, adding details, and sculpting if necessary.
Texturing and Materials:
Apply materials and textures to your model. This is crucial for visual fidelity, especially when transferring the model to other 3D applications or game engines.
Be mindful that FBX compatibility with complex Blender node setups can be limited. Simple image textures are generally more reliable.
Rigging and Animation (if applicable):
If your model needs to be animated, create a rig (armature) and animate it within Blender.
FBX supports animation data, making it suitable for transferring animated models.
Preparing for Export:
Apply Modifiers: It's often recommended to apply any relevant modifiers (like subdivision surface) before exporting. This ensures that the exported model's geometry matches what you see in the viewport.
Transformations: Apply all transformations (scale, rotation, location) to your objects (Ctrl + A). This helps avoid unexpected issues with object placement in other programs.
2. Exporting to FBX:
Go to File > Export > FBX (.fbx):
This opens the FBX export settings.
FBX Export Settings:
Path Mode: If your model uses image textures, set the "Path Mode" to "Copy" and enable "Embed Textures." This ensures that the texture files are included with the FBX file. However, be aware that embedding textures can increase the file size.
Object Types: Choose which object types to include in the export (Mesh, Armature, etc.).
Transform: you can have the apply transform box checked, to make sure the transforms are applied on export.
Limit to Selected Objects: If you only want to export certain objects, select them in the viewport and enable this option.
Armature settings: if you are exporting animations, there are armature settings that can be adjusted.
Choose a Location and Filename:
Select the directory where you want to save the FBX file and give it a name.
Click "Export FBX":
This generates the FBX file.
