: Large textures and massive polygon counts can cause the viewer to crash on mobile devices or lower-end computers due to lack of RAM. Try optimizing your meshes and lowering texture resolutions (e.g., from 4K to 2K) before exporting. I need to cover causes, solutions, technical details,

Beyond the software of the browser, the hardware capabilities of the user’s machine play a pivotal role. Real-time rendering is an intensive process that offloads calculations to the Graphics Processing Unit (GPU). Unlike a standard video, which is a pre-rendered sequence of images, a Marmoset Viewer calculates lighting, shading, and geometry in real-time. If a user’s computer has outdated graphics drivers or an integrated graphics chip that lacks support for the specific shader models required by the scene, the initialization process will halt. The error message is essentially the software’s way of saying the hardware does not meet the minimum requirements to draw the image. This is particularly common in workplace environments where computers are not optimized for graphical tasks, or when users have neglected to update their GPU drivers.

Sometimes WebGL is blacklisted by your browser due to older GPU drivers.

Marmoset Viewer is a that allows users to showcase 3D scenes from Marmoset Toolbag in a web browser. The process involves:
