This allows for better UI responsiveness on weak GPUs or on complex scenes. Toggle tile rendering on and off to render only part of a frame at a time. You can choose from three formats: PNG, JPG, HDR Upload the scene to cloud storage in your account for viewing/sharing it in Light Viewer for Web These operations apply to transformations, changes in the properties of materials or light sources Fits all objects in the 3D scene in the viewport Return the camera to its default position. In the center at the top of the window, you see a row of round buttons, they provide quick access to the most important functions: Button The Burger menu in the upper left corner allows you to save and load scenes, as well as export rendering output in PNG, JPG, and HDR formats: For example, they can be used as masks for applying desired effects. Render passes are useful for post-processing the rendering in image-editing software. For example, if you choose Normal pass, the normal map will be displayed in the viewport instead of the final render. To the left of the SPP field, there is a dropdown menu allowing to switch the render pass to display (Render, Normal, Albedo, Depth, Index). The more complex the lighting (scenes dominated by indirect illumination and/or caustics), the more SPP we need to achieve the noise-free result. In physically-based renderers using path tracing as a visualization algorithm, this parameter is controlled by the user and adjusted depending on the scene, more precisely, on the complexity of the lighting. You can increase the number of samples (SPP) to improve the quality of the render (reduce the noise). It shows the readiness of the final render. At the top border of the window, you may see a green progress bar. After the import is complete, we will see our model: Typically, you may want to boost their brightness 3-5 times for more realistic results. In the case of glTF, you can set the Emission boost parameter, which allows you to increase/decrease the brightness of all glowing objects in the scene. There are some settings specific to a particular format. The Auto parameter means that Light Tracer will use the default axis corresponding to the selected format (for example, for glTF this is the Y-axis). As you drag the model, an import dialog opens where you can select settings, such as the vertical axis used by the model: Along with this, Light Tracer supports import from 3D file formats such as OBJ, STL, FBX, DAE, VOX (MagicaVoxel), and CAD formats like STEP, IGES, 3DM. The zipped glTF file downloaded from Sketchfab can be dragged into Light Tracer directly, and you don't even have to unpack it. We liked the cosmetics model ( ) by The Motion Tree. To get started, you can download some models from Sketchfab, where you may find a lot of great artwork. The easiest way is to drag the model file into the Light Tracer window. The instructions below apply equally to the native and web versions of Light Tracer Render. This tutorial covers the basic principles of working with Light Tracer Render, including importing 3D models, setting up the camera view, adjusting the HDRI environment map, assigning materials, and exporting the rendering result. To confine the illumination to a specific area for optimization purposes, you can use the PxrPortalLight with a PxrDomeLight to focus sampling for things like interiors with windows and skylights.This tutorial is designed to introduce you to Light Tracer Render You may also have more than one in a scene for flexible lighting and linking to objects and portal lights. Only rotation matters so you can position your lighting accordingly. It works via Image Base lighting (IBL) to illuminate sets and characters with an environment map. Note that scaling and translation for this light will be ignored as it's considered nearly infinite or at least very far away. This light simulates environment lighting. This can be solved by using an image editor to selectively increase the exposure of these light sources or mapping these light sources to area lights and altering their Exposure or Intensity. If you find your shadows are too soft or too light in density, it's because the light sources in your HDRI are not sufficiently powerful enough. Understand that light sources (even man-made sources) are relatively high energy compared to their surroundings. To avoid this we suggest EXR, HDR, or TIFF floating point images captured with multiple exposures. Using low dynamic range or 8-bit images like JPEGs might produce acceptable reflections but the lighting will be dull and mostly flat. When we talk about HDRI lighting, we mean full floating point (or half-float) images with light values well above 1.0 to produce lighting.
