Object Render Region material swapping


Arion v2.5.0 object-based render region material swapping. Scene by Surreal Structures

Dear Arion users,

We have just posted a brand new tutorial on our Knowledge Base site.

This tutorial explains how to use the Object-based Render Region feature to o material swapping in compositing.

The basics presented in this tutorial will help you save a lot of time when it comes to producing many images of the same scene where just one or several objects must be shown in different colors. The process can even be partially automated through RenderWarrior for an even greater time saving.

New tutorial on GI bounces and Exit color


Arion v2.5.0 finite sampling tutorial

Dear Arion users,

We have just posted a brand new tutorial on our knowledge base site.

This tutorial explains in detail how to get the most out of the GI bounces and Exit color features.

Following this thoroughly will help you dramatically improve your render times without damaging the incredible output quality that Arion delivers.

The Arion Knowledge Base

Dear Arion users,

Earlier this year we started a Knowledge Base (KB) that would take the place of our old User Manual, tutorials and documentation, which over the years have taken the form of .pdf documents, and even a Wiki page.

This summer we finally decided to adopt a well-established solution called Confluence, which allows us to easily add new entries collaboratively. We ported everything from the old KB to the new one, and lately we have been working hard in order to get it ready by the release of v2.5.0.

You can access the new KB following this link:

http://support.randomcontrol.com

The KB starts to be very complete (at last!). We’re still working on a full review to fix typos, add more illustrations, etc… We expect it to be formally complete and fully up-to-date in the upcoming weeks.

The KB has been fragmented in the following areas:

1- The Arion Knowledge Base (features of the core, common to all our products).
2- Arion stand-alone.
3- Command-line tools.
4- MAX LIVE.
5- RHINO LIVE.

The area for RCSDK have not been released yet.

Thanks for watching!

Ways to use the Arion AOVs to denoise a conflictive render

Arion becomes more robust version after version and we’re already offering a very powerful set of features which allow the user to fight fiercely against noise and render times. However, sometimes your scene is either too complicated, or you’re unsure where your noise is coming from, or you’re about to meet your deadline and need an easy way to stay out of trouble and get a clean render.

In this short tutorial we will study the case of a render that is mostly clean except for some caustics.

NOTE: This particular example has been set up to generate excessive noise and fireflies from specular surfaces.

Method #1: Using the Main and Caustics AOVs

To achieve our denoising goal with this method, all we need to do is enable the Caustics AOV and let Arion render until most of the image is clean.

The Main AOV:

The Caustics AOV:

By subtracting the Caustics AOV from the Main AOV, we get a clean render of the full GI, minus caustics:

We can carefully denoise or despeckle the Caustics AOV to remove all the fireflies:

Now we can add the despeckled Caustics AOV to the Main AOV and get the final (clean) image:

Method #2: Using the Direct/Indirect AOVs

This method is similar to the previous one, but requires fewer editing steps.

Note that for this method, you may need to enable the Lights AOV as well, as direct vision of light sources is not included in the Direct/Indirect AOVs.

Here is the Direct AOV:

Here is the Indirect AOV:

And here is the Lights AOV:

Just like in the previous method, we carefully denoise or despeckle the Indirect AOV:

Then we add it back to the Direct AOV, without forgetting to add the Lights AOV as well, in order to restore the full image:

As you can see, using Arion’s v2.5.0 AOVs, it’s possible to get out of a difficult rendering situation without sacrificing quality, when the deadline is about to expire.

Note that, in both cases, denoising the Caustics/Indirect AOVs is virtually non-destructive to the final image, because most of the sharpness and evident details in the render are present in the Main/Direct AOVs, which remain intact through the process.

Note also that, strictly speaking, all these operations must happen in HDR (linear) space so addition and subtraction of AOVs is correct.

Thank you for watching!

Some new entries in the KB

We have just added some pages to the Arion Knowledge Base. They affect some of the new features in v2.4.x, so they are probably worth reading:
