How does converting FBX to GLB work?
In order to successfully convert an FBX formatted file to the GLB format, our converter tools will perform several initial checks to ensure the file provided is indeed an FBX file. There are many files out there where the file type extension does not match the data contained within the file. Along with these file type checks, our tools will do additional checks to ensure the file is correctly formatted to match the provided file type. There are many tools out there that do not always create FBX files to the exact specification.
Take your FBX file
The FBX file format can be either a text-based or binary format, meaning if its content is plain text, it is human-readable; otherwise, if it is binary, then it can only be edited with specialist FBX editing software. The data within the file, regardless of whether it is text or binary, contains the core elements that make up the 3D model, including vertices, faces and more. To guarantee efficient conversions, our tool will check all data that is contained within the FBX file and remove any information that is duplicated. This not only ensures the conversion completes more quickly, but also that the generated GLB is smaller.
Along with the core data that makes up the 3D model, our tool will check the FBX file for the presence of texture coordinates to ensure any texture-based materials are converted correctly. Even if the texture files are not presented with the FBX file, our converter will preserve any texture coordinates when converting to the GLB format.
Convert the data from FBX to GLB
Now that the data from the FBX file has been processed, our tool can apply any conversion specified options, such as enabling Voxel mode, and with these applied, prepare the data to be converted to the final GLB file format. Part of this process ensures checking the capabilities of the GLB format and removing any data that cannot be represented.
Save to the GLB format
At this point, the FBX to GLB conversion tool will have the 3D model in a state that is ready to be transferred to the GLB format. Our tool creates the GLB file, ensuring all the model data is present and is formatted to match the GLB file specification to ensure the file opens in compatible GLB file editors.
If the FBX file contains texture images, these will be exported to a format that is compatible with the GLB format. For most textures that are stored as JPG or PNG images, these are transferred with no changes. However, if there are other formats, such as TGA, these will be converted to a suitable format.
If an FBX texture does need to be converted to a different image file format, our tool will ensure the quality and resolution are not degraded during the conversion process.
