Yulio Jump for CET: Working With Lighting

Yulio Jump was designed from the ground up to be the quickest most efficient way of getting your design concepts in VR. With Yulio Jump for CET Designer, you have three different lighting models to chose from and two primary methods for lighting your space.

Methods for Lighting your Space

Method 1: 

Lighting Model: CET Native Lighting Model

Yulio Jump is now compatible with native CET lighting and HDR environment mapping. This lighting model will provide the most realism for your space, however it does require basic knowledge of native CET lighting. The CET Native Lighting model in Yulio Jump will render any lights you have placed in your space through CET lighting and acknowledge them as light sources, meaning the lights will be on. Additionally, with the CET Native Lighting model in Yulio Jump, you can add an environment outside your windows using an HDR environment map. For detailed instructions on using the CET Native Lighting model and HDR Environments, check out this article.

Method 2:

Lighting Models: Interior/Shaded Lighting Model or Exterior/Bright Lighting Model

Method two requires minimal user modification because it uses a smart ambient lighting model to light your scene. For this option you would use Yulio Jump’s Interior or Exterior lighting models – these lighting models will render any lights you have placed in the scene as objects, however, no light will be coming from them. The Interior and Exterior lighting models are the simplest to use because you don’t have to worry about adding any of your own lighting to your space.

Lighting Models

Within the Yulio Jump plugin, you will have three lighting models to choose between to render your scene: CET Native Lighting, Exterior/Bright and Interior/Shaded. Let’s discuss the benefits of each so you know which one will work best for your project.

1. CET Native Lighting

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. After you place your lights, head over to the Yulio Jump extension as normal and select the CET Native Lighting model to render. If you would like to add an HDR background environment, you must add this in PhotoLab using Image Based Light. For more detailed instructions, check out this article.

2. Exterior/Bright

The Exterior/Bright lighting model will work best in an environment with windows or perhaps a skylight. This lighting model accurately simulates what would happen in the real world as it simulates an artificial sun with a skylit/skybox type of lighting model. This lighting model is more physically correct than the Interior Lighting model – meaning that any shadows or projection in your scene will look more realistic to your brain, as the Exterior/Bright lighting model is literally simulating how light moves in the real world.

3. Interior/Shaded

The Interior/Shaded lighting model will work best in an environment with very few or no windows. This lighting model produces an artificial light source within the space and artificially adjusts the lighting so the space will be evenly lit. In this case, the lighting model will probe the scene to see if there are any areas that are darker than others, making it look as balanced as possible.

Depending on the size of your model, Yulio Jump only takes a couple of minutes so don’t be afraid to try it and see what your results look like!
