# Missing or Corrupt Frames When Exporting Animation Frames in KeyShot Studio for IronCAD

## Troubleshooting missing, corrupted, or incomplete PNG frame output during animation rendering.

#### **Issue Description**

A customer may experience issues when exporting an animation to a PNG image sequence in **KeyShot Studio for IronCAD**. Reported symptoms include:

- Animation exports cut off halfway
- Missing frames
- Corrupt or unreadable frames
- Lower resolutions (e.g., 400×400) exporting more successfully than higher resolutions (e.g., 1200×1200)
- Problems occurring after upgrading to KeyShot Studio for IronCAD

These issues appear when exporting PNG frames with a transparent background to be used in Adobe Premiere.

#### **Environment**

- KeyShot Studio for IronCAD
- Windows or macOS

#### **Cause**

Several factors can lead to missing or corrupt animation frames:

### **1. Resource or Output Folder Syncing to the Cloud**

If KeyShot’s **Resource Folder**, installation, or the destination folder for animation frames is stored on or synced with a cloud service (OneDrive, Dropbox, iCloud, etc.), file writes may delay, fail, or corrupt—especially with large or high-resolution PNG sequences.

### **2. Network or Shared Drive Usage**

Rendering directly to a network location or shared drive can cause incomplete output or frame corruption.

### **3. Incorrect Folder Permissions or No Local Copy Available**

Cloud-managed folders sometimes offload files to the cloud, interrupting file writing operations needed during export.

#### **Resolution**

### **Save Animation Frames to a Local Folder**

- Choose a local directory such as:  
  `C:\Users\<username>\Documents\KeyShot Renders\AnimationFrames`
- Ensure the folder **is not** synced to OneDrive, Dropbox, Google Drive, iCloud, etc.
- Avoid rendering directly to network drives or external storage.

**Additional Notes:**

If the issue persists, please contact KeyShot Support with screenshots, system information, and the license type currently activated on each device.
