X-Ray Select earns its place for targeting a specific limitation: Blender's built-in X-ray applies to the whole scene at once, while this add-on isolates X-ray to the objects you select and ties the toggle to a shortcut key you choose.
X-Ray Select is a Blender add-on that changes how X-ray mode works in the viewport. Blender's default X-ray shows every model in the scene at once, which makes it hard to focus on a single object. X-Ray Select lets you switch only the models you select into X-ray, isolating the exact components you want to see while the rest of the scene stays solid.
The add-on adds custom shortcut key assignments, so you can toggle X-ray on and off for selected objects using the key of your choice. After installing it, you pick an object, press your shortcut, and switch it in and out of X-ray view as you work through complex models.
The isolated model X-ray approach is intended to feel familiar to artists coming from 3DS Max or Maya. Documentation is included, and a demo video is available. X-Ray Select is developed by PLAYSYNC PTE LTD for Blender.
X-Ray Select : Limited Sale is best for 3D artists and modelers working on complex models in Blender, technical artists focusing on specific geometry, and modelers transitioning from 3DS Max or Maya.
X-Ray Select : Limited Sale is completely free to download and use.
X-Ray Select changes how X-ray applies in the viewport. Blender's default X-ray mode shows every model in the scene in X-ray at the same time, so you cannot easily focus on one object. X-Ray Select instead switches only the models you select into X-ray mode, isolating individual objects while the rest of the scene stays solid. That gives you a focused view of the specific parts you want to work on without the clutter of the entire scene.
X-Ray Select supports custom shortcut key assignments, so you can pick the key that fits your habits. Once installed, you choose the object you want to view in X-ray mode and toggle it on and off with the shortcut key of your choice. Customising the shortcut lets you switch selected objects in and out of X-ray without repeating the same manual steps, keeping the toggle within easy reach while you model.
X-Ray Select offers isolated model X-ray functionality aimed at artists transitioning from 3DS Max or Maya. Rather than showing the whole scene in X-ray, the add-on switches only the objects you select into X-ray mode inside Blender, isolating individual models. The developer describes this isolated approach as familiar and flexible for people used to those applications, giving them a way to inspect and refine the specific geometry they want without the clutter of the entire scene.
X-Ray Select is listed as free in this catalog. Licensing terms can change over time, so check the developer's page for the current details before you download. The add-on is a Blender modeling tool from PLAYSYNC PTE LTD that adds isolated X-ray for selected objects, and documentation is included to help you get set up and start toggling X-ray on your chosen models.
