Yulio Jump for CET: CET Native Lighting Model & HDR Environments

Yulio Jump is now compatible with native CET lighting and HDR environment mapping, using the new CET Native Lighting model in the Yulio Jump extension. 

This lighting model will provide the most realism for your space, however it does require basic knowledge of the CET Lights extension. The CET Native Lighting model in Yulio Jump will render any lights you have placed in your space through the CET Lights extension and acknowledge them as light sources, meaning the lights will be on when rendered. 


With the CET Native Lighting model in Yulio Jump, you can also add an environment outside your windows using an HDR environment map for added realism. 


In this article we will cover some recommended settings for lighting and how to add an HDR environment map outside your windows. Please note these are just recommendations, for further support on CET lighting contact Configura support directly. 


If you are new to CET lighting – Configura has some great resources on getting started with lighting.

 
How It Works: Native CET Lighting Model

In order to use the CET Native Lighting model, you must first place lighting into your space using the free CET Lights extension. This can be anything from Fluorescent lighting, ceiling lights, sconces, desk and floor lighting from within the CET Lights extension. 

The amount and type of light is going to change for every model you work on, below are recommended settings for what we have found works best through testing. Please note, this may need some adjusting depending on your space.

Our recommendations, using Fluorescent Ceiling Lighting:




Note: For the light type setting, you can use any light type you like however each type emits different levels of light. We recommend testing or adjusting the number of ceiling lights if you plan on switching to a different light type.


After you place your lights, head over to the Yulio Jump extension as normal and select the CET Native Lighting model to render.

How it Works: HDR Environment Mapping


If you would like to add an HDR background environment, you can add this in PhotoLab using the Image Based Light setting. To render an HDR environment with Yulio Jump, you must use one of the environment maps native in CET, importing your own will cause issues.

 
To add an HDR environment map, start out by opening PhotoLab.

In PhotoLab, start out by making sure your photograph setup is using realistic lighting. To apply realistic lighting, scroll down in the left side panel and hit the Simple button.

From there, select the realistic box.

Under the Realistic menu, select the Background thumbnail image. This is where you can download any HDR images you wish to use for your project. You do not need to adjust any other settings here.


Download an image by clicking on one of the cloud download icons.

Next, simply scroll back down and select the Advanced button to go back to the Advanced settings panel.

Next, open the Lighting & Shadows tab.

Next, select the top drop down menu and select Image Based Light. 

Please note, Image Based Light is the only lighting model on this menu that is compatible with Yulio Jump. This is because Yulio Jump is a physically correct rendering engine and from this menu Image Based Light is the only physically correct lighting model.

Under the Image Based Light panel, click on the thumbnail to select which background environment you would like to use for your project.

Next, check off the Use Image as Background button.

Please note, if you have already created multiple scenes in PhotoLab for your project – you will need to go scene to scene to apply the HDR background to each scene. 

We recommend creating your first scene, applying the HDR background and then creating the rest of your scenes in PhotoLab so the HDR environment gets auto applied for you.
 
And that’s it! Once you have created all of your desired scenes, head over to the Yulio Jump extension and render with the CET Native Lighting model.

Insider Tip – All HDR environments available in CET will emit different types of light based on the environment you select. For example a bright snowy landscape will emit a much brighter light than a greenspace.
