Mineimator is a popular animation and modeling software that allows users to create custom rigs for characters and objects. However, if you want to use your Mineimator rigs in other 3D modeling and animation software, such as Blender or Maya, you'll need to convert them to the OBJ format. Here's how you can do it:

1. Export the Rig: In Mineimator, select the rig that you want to convert to OBJ and export it as an .miobject file.

2. Convert to JSON: Once you have the .miobject file, you can use a JSON converter to convert it to a JSON file. There are several online tools and software programs available for this purpose.

3. Convert to OBJ: After converting the .miobject file to a JSON file, you can then use a JSON-to-OBJ converter to convert it to the OBJ format. Again, there are various tools and software programs that can help you with this step.

4. Import to 3D Software: Once you have the OBJ file, you can import it into your preferred 3D modeling or animation software. You may need to make adjustments to the materials and textures, but the basic rig should be ready for use.

By following these steps, you can easily convert your Mineimator rigs to the OBJ format, allowing you to use them in a wider range of 3D modeling and animation software. This can be especially useful if you want to integrate your Mineimator creations into larger projects or workflows. Keep in mind that the conversion process may vary depending on the complexity of the rig, so be prepared to make adjustments as needed. With a bit of patience and experimentation, you'll be able to seamlessly transition your Mineimator creations into your preferred 3D software environment.
