When you change clamp values, be sure to pay close attention to the brightest samples of your scene when making changes. The only issue with this is that if the clamp values are set too low, the image quality will blur and darken, giving your render a thin, low-contrast look.
This value is typically set to cut out-of-range or garishly bright samples in a scene, but some users tend to set their clamp settings too low thinking that this will save on light bounces and therefore improve render times. What clamping does is limit the high brightness values of a scene and help reduce fireflies (dead, burnt-out pixels). Low Clamping ValuesĪnother area of debate in the Light Paths section is clamping. With that in mind, you can set a maximum value of four to six bounces, but anything below that will result in a significant decline in quality in your final renders. In practice, a slightly smaller number of bounces is enough to simulate real-world light patterns. The only way one can try to simulate those bounces is to have a lot of them, or else, the shadows will certainly be darker than a similar scene in the real world.īlender’s default Max Bounces count is 12. In the real physical world, there are an infinite number of light bounces. The problem with this thinking is that it defeats the purpose of having any light paths or bounces at all.
One mode of thought comes to mind: “What is the bounce setting’s influence on noise in renders? I’ve been told that if I want less noise in my image, I should reduce the bounces.” The backbone of any successful rendering engine is its ability to accurately compute light and how it bounces on objects. At Render Pool, our affordable render farm can greatly increase the quality of your Blender renders at the speed you want. If you’re running your 3D software or renderer on a weak system, the first thing you’re likely to end up doing is dropping your sample count and that alone will drastically decrease the quality of your final render.Īn easy solution to this problem is to move your local rendering to a cloud-based service. Many new and seasoned designers alike do this for test renders and animations, but rarely does a final render finish rendering as quickly as you want it to.ĢK/4K renders and AOV passes are very processor-heavy operations. Rendering locally means using your own workstation to render scenes. Let’s take a look at some things to watch out for and what you can do instead! Rendering Locally If upgrading your hardware isn’t an option, you may try to change your settings to speed up rendering, which often sacrifices quality in the process. Depending on your workstation’s specifications, rendering a scene can be an excruciatingly slow process.
