finalRender Subscription Drop 1 : AI Denoiser New Feature
20Firstly, please Subscribe, if you have not. Support cebas channel for more tutorials and videos! Thank you.
Welcome to the Cebas Visual Technology's finalRender New Features Video #1. In this video, Edwin Braun shows you one of finalRender most powerful physically-accurate rendering with NVIDIA AI Denoiser, OptiX. Operate with finalRender trueHybrid(TM) right from 3dsMax, fully integrated.
WHAT IS ARTIFICIAL INTELLIGENCE DENOISER?
Artificial Intelligence in the form of a neuronal network drives the latest denoiser functionality of finalRender. This latest advancement in rendering technology allows to cut render times easily in half or even more. Scenes that might render 12 hours can be rendered in 35 Minutes without much visual difference at all.
3ds MAX ACTIVE SHADE MODE
In this New Feature Video, Edwin Braun starts with GI model scene in the 3dsMax ActiveShade mode. The daylight system is the source of light that entails much bouncing rays and hence, we expect a lot of noise in the image. The scene is set at a low pass iteration of '32'.
To deal with the noise, all users have to do is On / Off the Denoiser button at fR Render Setup window. Cebas one button rule is designed to save time (and therefore costs) and offers flexibility of achieving optimal rendering whether you are on a GPU / CPU or hybrid applications. Play with it and see the change in noise pixels.
Note the original image 'denoised' is always kept saved as a separate file: 'fR Complete' (see under Render Elements.)

PRODUCTION RENDERING MODE: the 2nd POST-FILTER DENOISER
Edwin then does the post-filter denoising (see under the FrameBuffer menu) in Production Render mode: you can review the effects of the Post-Filter AI Denoiser effect in comparison with the original rendered (denoised) from Active Shade that was done earlier (see below of the FrameBuffer menu.) You can Enable / Disable this Post-Filter Denoiser under the 'Filter' tab in FrameBuffer. It runs the denoiser as like the Render Setup denoiser but the results are different.
The Production Rendering Mode - FrameBuffer AI Denoiser gives you, the User, the post-filter effect and it has less to work with, so at render times, more data gets to be passed on to the denoiser filter.
WHY POST-FILTER DENOISER ?
To answer you, the 1st level of denoising in Active Shade on Adaptive Sampling (see the next video #2) gives a quick rendering at high iterations and a speedy removal of overall noise. And then you come back on the 2nd level post-filter denoise (if you desire varied image effects) and adjust the amount of denoising to bring back some details.
ADVANTAGE OF A POST-FILTER DENOISER ?
Scene #2: Bathroom:
In this scene where there is a lot more details than the cathedral, with more objects and more direct and indirect lights. We set passes to a low of 50 (for speed rendering and leaving in some noise so we can compare details). Remember to ENABLE the Denoiser (off by default).
For this bathroom scene, what Edwin wanted to highlight is the 'Behind the Glass' effects: you see it is not photo- realistic at the point of rendering - a lot of unwanted noise remains 'behind the glass'.
However, with the 1st denoise, if you recall, fR complete (the original rendered scene), indeed a lot of noise was removed.
Now, enabling and adjusting levels from the FrameBuffer Post-Filter Denoiser, you see just how much control you have on cleaning up the image and selecting how much details you want to recall - Non-Destructive rendering. It makes a significant difference. Get you free trial version or get the Pro at cebas.com/finalRender now.
