When sculpting a 3D model, camera flickering typically stems from the viewport struggling to handle high polygon counts or real-time mesh changes during sculpting.
Sculpting adds dynamic detail (like subdivisions or tessellation), increasing mesh complexity and overwhelming the GPU’s ability to refresh the viewport smoothly—this mismatch causes flickering. Outdated graphics drivers, unoptimized viewport settings (e.g., too many active layers), or limited hardware resources (such as low VRAM) can also worsen the issue.
To fix it, try temporarily lowering the sculpt tool’s subdivision level or updating your GPU drivers—these simple steps often reduce viewport strain without affecting your work.
