The barrier to entry in “UX” in general is much lower than ID. The fact that most things live as pixels on screens (not everything, but most) means you can use the same tools you are familiar with (Photoshop, Illustrator) to mockup designs. There are tons of articles written on UX process (wireframing, information architecture, usability testing) that are very analogous to sketching, HF testing, etc.
If your company builds products chances are there are elements of UX easily available for you to work on. That could be anything from your company website, software that comes with a product, LED behaviors or simple displays on the product itself, instruction manuals, etc.
Once you understand design thinking and the approach to solving a problem transitioning from 3D to 2D is much easier than it would be for someone who is an expert in 2D wire framing to transition to be a CAD surfacing pro. A lot of UX isn’t about reinventing the wheel, it’s about assigning meaningful hierarchy to information and using patterns which are common and easily understood. Anyone who uses a smartphone has a good idea about what good UI and bad UI looks like these days.
