When it comes to VR and AR design, there are various tools available ranging from general-purpose 3D software to specialized applications and frameworks. Popular and widely used tools include Unity and Unreal Engine, Blender, Adobe Photoshop and Illustrator, as well as Sketchfab. Unity and Unreal Engine are powerful game engines that enable the creation of 3D scenes, animations, scripts, and effects for VR and AR. They also have built-in support for various VR and AR devices and platforms. Blender is a free open-source 3D software that allows users to model, sculpt, texture, rig, animate, and render 3D objects. Adobe Photoshop and Illustrator are the industry-standard tools for creating and editing 2D graphics. Finally, Sketchfab is a web-based platform that enables users to upload, view, share, and embed 3D models in VR and AR with its built-in editor for adjusting materials, lighting, and post-processing effects.
