Dear Unreal Engine Pro Support Team,
Warm greetings. We are reaching out as part of our ongoing efforts to optimize our Unreal Engine 5.6-based cinematic rendering pipeline. We are a production studio deeply invested in creating high-fidelity, non-real-time stereoscopic 3D animated films using Unreal Engine’s Movie Render Queue. Given the scale, complexity, and resolution of our current and upcoming projects, we would greatly appreciate your expert guidance on hardware utilization—specifically with respect to multi-GPU support.
Project Overview and Rendering Challenges
We are currently engaged in very high quality stereoscopic 3D cinematic immersive movie production. Our render pipeline is built 100% inside Unreal Engine 5.6, and involves:
- Final Output Format:
- Left Eye: 14K resolution
- Right Eye: 14K resolution
- Stereoscopic 3D, 60 FPS, Non-Real-Time Rendering
- Project Scale & Complexity:
- Per project size exceeds 500+ GB (compressed).
- Assets include extensive environments, hyperreal character models, and physically simulated elements such as:
• Large-scale Houdini caches (e.g., crowd systems, fluid sims)
• Ray-traced reflections, global illumination, and volumetrics
• Heavy use of VDB clouds, cloth, and particle dynamics
- Rendering Workflow:
- Using Unreal Movie Render Queue with anti-aliasing, temporal sample accumulation, and full resolution renders
- Target output formats require 14K x 2 (stereo) image sequences for post-production
Current Hardware Usage
- Workstations with RTX 5090 (32 GB VRAM)
- We are currently utilizing RTX 5090 GPUs, but are facing memory limitations, especially with large scenes involving VDB, groom hair, and complex simulations.
- Scene crashing and performance bottlenecks are occurring during Movie Render Queue tasks when dealing with full-resolution stereo assets and dynamics.
Planned Upgrade Path – Query for Validation
We are planning to invest in NVIDIA RTX 6000 Ada GPUs (96 GB VRAM) and would like to know:
1. Will Unreal Engine 5.6 natively utilize dual RTX 6000 Ada GPUs installed in the same system during cinematic rendering via Movie Render Queue?
- If not, is there any recommended method to assign stereo rendering or batch sequences to separate GPUs using Unreal-supported configurations?
- Does Movie Render Queue or the rendering pipeline benefit from NVLink on dual RTX 6000 Ada cards?
2. Would it be technically and operationally better to split into two separate machines each with one RTX 6000 Ada card and run eye-specific renders independently?
3. Is the significant investment in a dual 6000 Ada GPU system justified, given our usage is exclusively within Unreal Engine’s cinematic (non-realtime) rendering path?
Need for Official Recommendation
We would be grateful if your engineering or technical advisory team could:
- Review our rendering pipeline use-case
- Confirm the GPU utilization limits and possibilities within Unreal 5.6
- Recommend the most efficient and scalable configuration (one powerful system with dual RTX 6000 Ada vs two separate render nodes with single GPUs)
We sincerely appreciate the incredible technology that Unreal Engine offers, and we are fully committed to pushing the boundaries of cinematic storytelling using your platform. Your expert advice on this investment decision will have a direct impact on our upcoming production capacity and delivery pipeline.
Please feel free to request any logs, render settings, or benchmarks if needed to evaluate our use-case better.
Warm regards,
