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, you have four different lighting models to choose from and two primary methods for lighting your space.

Methods for Lighting your Space

Method 1

• CET Native Lighting Model

The CET Native 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.

• Neutral Materials Model

The Neutral Materials lighting model will strip all color and texture from your scene and replace it with neutral finishes. Any lighting you have placed in your space will be acknowledged. If you have not placed any lights, Yulio Jump will light your space using the Exterior/Bright Lighting Model.

Method 2

• 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 plugin, you will have four lighting models to choose between to render your scenes: CET Native Lighting, Neutral Materials, 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

The CET Native Lighting model will provide the most realistic lighting among the four lighting models. In order to use this model, you must first place lighting into your space using the free CET Lights extension. This can be anything from the CET Lights extension, including fluorescent lighting, ceiling lights, sconces, desk and floor lighting. 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. Neutral Materials

The Neutral Materials Lighting Model strips all color and texture from your space and replaces it with neutral finishes. This model was created for those times when you want your client to get a feel for the layout of the space and the configuration of furniture before focusing on color, material, and texture. 

In order to use the Neutral Materials Lighting model, you must first place lighting into your space using the free CET Lights extension. This can be anything from the CET Lights extension, including fluorescent lighting, ceiling lights, sconces, desk and floor lighting. After you place your lights, head over to the Yulio Jump extension as normal and select the Neutral Materials 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.

3. 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.

4. 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 will only take a few minutes to render your project, so don’t be afraid to try different lighting models to see which one works best for your VR experience.
