Converting and Optimizing VRM Files to glTF
There are various ways to convert between VRM and glTF. With RapidPipeline, you can easily convert and and optimize VRM files, at scale. It supports glTF, as well as many other file formats (examples: 3dsMax, FBX, OBJ, PLY, STEP, STL, USD, USDZ), at high quality.
Due to the potential limitations aforementioned on the table above, in principle, one cannot always perfectly convert 3D data between glTF and other formats. In the following, you can find conversion guides between glTF and the most important other formats, along with a rough score for compatibility of this workflow:
What's the best way to get VRM files into my 3D applications, and are there alternatives to using glTF?
Doing 3D conversion right, especially at scale, can be tricky, as 3D data is in general a rather complex (yet very powerful!) medium. This also applies to VRM and glTF files - the conversion guide above provides a rough first idea about that. Once you know what you would like to do, tools like RapidPipeline can help you perform the necessary steps, and to even automate the process for thousands or even millions of files.
Especially when introducing pipelines and workflows at scale in an enterprise context, it is usually good to rely on dedicated tools and expertise, making sure you do not introduce any steps into your 3D workflow that are detrimental to the final output's quality, or that take your team too much time (and money).
If you're interested to hire dedicated expertise from the best in the field to help your company reach your goals fast and reliably, please do not hestitate to contact DGG. Being the creators of RapidPipeline, and ambassadors for open 3D standards for more than a decade, we have been building some of the world's most advanced 3D pipelines, having processed many millions of 3D assets.
