3ds Max V-Ray Render Crash or Out of Memory

How to fix it

Try these in order — the most common fix is first.

1. 1. Reduce memory load

   Copy steps
   1. Lower texture sizes and displacement subdivision
   2. Use V-Ray proxies for heavy geometry
   3. Leave the raycaster geometry setting on auto instead of static
   Did this fix it? Yes No

2. 2. Trim frame buffer overhead

   Copy steps
   1. Disable the 3ds Max Rendered Frame Window
   2. Disable V-Ray's render-to-memory frame buffer and save to disk
   Did this fix it? Yes No

3. 3. Enlarge the Windows paging file

   Copy steps
   1. Open System > Advanced system settings > Performance > Advanced > Virtual memory
   2. Set a large custom size on a fast SSD; users report this stops crashes but slows renders once RAM runs out
   Did this fix it? Yes No

4. 4. GPU mode

   Copy steps
   1. Update the GPU driver and keep V-Ray and Max versions matched
   2. Note a second GPU does not add VRAM; reduce scene size or add RAM instead
   Did this fix it? Yes No

Symptoms

3ds Max closes or freezes mid-render, shows an out-of-memory error, or V-Ray GPU crashes on heavy scenes.

Why it happens

• Scene needs more RAM than installed (heavy displacement, proxies, VRayFur, large textures)
• Static geometry setting loading everything into memory
• Render frame buffers consuming extra RAM
• GPU mode exceeding VRAM or driver mismatch
