Dealing with noisy scenes!
This article will show you how to deal with scenes having too much noise or fireflies. Most of the time this happens when the scene setup is wrong. Let’s see them one by one and try finding the best ways to fix them.
Using the Thin Film Layer as Coating
Learn how to make a Thin Film layer to act as Coating in a multi-layered material. Complex materials can be created when combined with the Interference option of the Thin Film layer.
Floating Point Precision may cause Rendering Artifacts
Rendering artifacts may appear when a model has been moved away from the origin or its dimensions are out of this world. It may lead to unconnected/jagged edges and bad tessellation to the surface. The only way to overcome this is to either move the model near to the origin or scale it up/down to the physical size.
How to properly setup Depth of Field
Depth of Field is controlled by the f-number that can be found in Camera Settings. The default value is “Pinhole” and it totally removes the DOF effect from the scene. By selecting any other value, you can control DOF. By default, Camera settings have Auto-Focus enabled and this means that even if you set a custom focus distance, it will be overridden by auto-focus. Unchecking Auto-Focus will make Thea use the focus distance that was set by the user.
Creating Fog with Thea for SketchUp
From v1.5.09.539.1462 onwards, it is easy to add and modify fog in a scene with two new options. Read through this article to learn more.
Making Thea Darkroom to show minimum settings

Adding Custom Presets for Adaptive BSD
We can create custom presets for the Adaptive BSD engine and to do so we will have to create them in Thea Studio.
Rendering in Full Resolution
Thea for SketchUp can operate either in Interactive or Production Mode. Even if we have selected a high resolution from the Camera Tab (Thea Tool window) while rendering in Interactive Mode, the resolution adapts to the size of the Thea Darkroom window. The same thing happens when we the in SketchUp window option is active.
Using the Color Shader in Cinema 4D
The Retransferred Material option has been created to support the Color Shader when it is being used with a Cloner Object. As you can see in Image 1, we have a basic scene with a Cloner and a Thea Material assigned to the Child Object (Cube).
Network Rendering Workflow in Cinema 4D
Network Rendering requires Thea Studio to be installed and activated to all the computers in your network.
Now with Thea activated, there two ways to use Network Rendering from inside Cinema 4D.
Plugin is not visible inside Cinema 4D
To make sure that Thea for Cinema 4D is working properly and the plugin is visible, you have to update Cinema 4D to the latest version.
Missing files with Team Render
When rendering with Thea through Team Render, you may experience missing textures and models with black surfaces. This is due to the fact that the network machines have started rendering before receiving the scene’s assets.
Saving a PNG image with Alpha in Rhino
Find out how to save an image along with its Alpha Channel by following these simple steps.
Using Multiple Mapping Channels
Multiple UVs in Rhino are being supported by Thea.
The most important thing to have in mind, is that UV Channels in Rhino start from 1, while Thea Render starts from 0.
Thea Lights Properties & Thea Materials not visible in Rhino
If Thea for Rhino is not set as the Current Render, then Thea specific properties for lights, like Visibility, will not be available. You will also see a different dialog everytime you create a new Thea Material.

If your Viewport in Thea Render Studio is sluggish for large scale model with heavy geometry you can opt to enable option “Use Level of Detail” and “Limit max drawn triangles (per model).
Disable Presto Warning for systems without NVIDIA graphics
Thea Render v1.5 currently provides support for NVIDIA adapters for CPU+GPU rendering with Thea Presto. In case your system only has AMD or Intel graphics, then during start-up of Thea Render Studio you will be receiving a warning from Presto on the bottom right corner.
Improving fluidity in Thea Studio while in IR
Please note that in multi-GPU configurations if the display card is also used for rendering, this will cause the viewport in Thea Studio to possibly stutter because core utilization is reaching peak levels while not allocating enough processing capacity to handle the display effectively.
