Physical Render – Adaptive VS Progressive

A good way to save time during a project is to cut down rendering time. But how to do this without spending a fortune for new, more and powerful Hardware?

Simple: Know your renderer!
If you know how your render engine is working and which settings are important you can save a load of time, like in this case: Knowing when to use Adaptive or Progressive can make a huge difference. Where you can simply just render everything on medium or high in adaptive mode without worrying about the details, it can save a lot of time to switch to progressive.

Here we have some simple reflective materials, some highly reflective and mat, others rather diffuse. Notice how the diffuse parts (rubber, plastic) don’t differ a lot between the renders? The only big difference is that the mat car paint is more grainy due to it’s high roughness in the reflective channel.

If you don’t have a lot of high roughness materials in your scene consider switching to progressive. Even if you do have rough materials you can still consider progressive for it adds some sweet subtle grain in comparison to the same render time in adaptive, which seems to smooth out any grain and makes it more clinical. Yikes!

So if you want to save some time don’t just adapt to your circumstances, be progressive and think about your scene!
