Your modifiers 3D model flickering in ZBrush typically stems from three main issues: conflicting modifier stack order, high polygon density straining the viewport, or outdated graphics drivers.
- **Modifier order conflicts**: Tools like Subdivision or Dynamesh don’t interact well if applied out of sequence, causing display glitches. - **High polygon count**: Too many polygons make ZBrush’s real-time preview struggle to render consistently, leading to flicker. - **Outdated drivers**: Old GPU drivers can’t handle dynamic effects properly, resulting in display errors.
Fix the flicker by reordering modifiers (apply Subdivision first), reducing viewport detail temporarily, or updating your graphics drivers.
