Yes, creating a logo maker in Blender and Blend4Web is possible. You can allow users to upload a logo or add text and apply it to a specific UV-mapped area on the 3D model. There's no need for a separate mesh—just define the texture space properly and use Blend4Web’s dynamic texture and canvas API to update the image or text in real time. This enables full customization like positioning the logo (e.g., 10% from top, 3% from left) without stretching.
