Smart Tips for Brender Cloud Users to Optimize Rendering Performance
Even the strongest hardware benefits from a well-optimized project. Cleaner scenes = faster renders = lower costs on the cloud. And if your local machine struggles, Brender Cloud is ready to handle the heavy lifting with GPU-powered instances. All techniques are based on Blender 4.4 and Cycles, but most apply to EEVEE too.
These optimization strategies will help you get the most out of Blender and Brender Cloud, reducing render times while maintaining quality.
Optimize render samples and use adaptive sampling to reduce noise efficiently.
Reduce bounce limits and clamp bright spots for faster light calculations.
Configure your hardware settings for maximum rendering performance.
Clean up meshes and optimize complex elements without losing quality.
Use global simplification settings to speed up your entire project.
High sample counts = longer renders. Try lowering 'Render Samples' under Render Properties ‣ Sampling for Cycles or EEVEE without losing too much quality. Preview tweaks in viewport samples first!
Save time by letting Blender decide when a pixel has enough samples. Activate 'Noise Threshold' in Sampling Settings.
Fewer samples + denoising = clean images faster. In Render Properties ‣ Denoising, choose a fast AI denoiser like 'OpenImageDenoise' or 'OptiX'.
Each light bounce adds to render time. In Light Paths, reduce 'Max Bounces' for diffuse, glossy, and transmission types. Start with low values and increase only if necessary.
Under Light Paths ‣ Clamping, set 'Indirect Light' clamp to something like 10. It helps kill annoying bright pixels without crushing your highlights too much.
Fancy light patterns like caustics are expensive to render and often not worth it unless your scene really needs them. Turn them off in Caustics Settings.
Always! Set your device in Preferences ‣ System. CUDA, OptiX, Metal — whatever fits your hardware. Brender Cloud provides powerful NVIDIA GPUs for maximum performance.
If you're stuck on CPU rendering, make sure your thread settings in Performance are optimized.
For big images, tiling is essential. In Performance ‣ Memory, set reasonable tile sizes: larger tiles for GPUs (256x256+), smaller for CPUs (16x16–64x64).
Delete faces that the camera won't see. Fewer vertices = faster renders.
Use Mesh ‣ Cleanup tools to reduce polycount without noticeable visual loss.
Cache simulations like cloth, fluids, or rigid bodies before sending to Brender Cloud. Go to Physics Properties and 'Bake' everything you can.
In Render Properties ‣ Curves, use simple shapes and limit subdivisions. Hair and fur can otherwise explode your render times.
Blender's Simplify lets you cap subdivisions, texture sizes, and particles across the whole scene. Great for quick test renders!
Under 'Simplify ‣ Culling', activate camera and distance culling to skip objects not visible or too far to matter.
Once your scene is tuned up, Brender Cloud will make your final renders fly. Save time, save money, and spend your energy where it matters — on the art, not the waiting!
Even small optimizations can lead to significant time savings when rendering complex scenes. The techniques in this guide will help you get the most out of Brender Cloud's powerful GPU servers.
