![]() 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. Hopefully something here helps - there are a few places that pathing can trip you up.This tutorial is designed to introduce you to Light Tracer Render Make sure that the naming is correct (“sketchfab.timeframe”) or it won’t get processed to make the animation. For the simple walk cycle that makes up my example (it cycles the frames twice) the timeframe reads like so: This is where the animation magic happens. Last but not least, we have the TimeFrame file itself. ![]() Using the file structure I’ve shown you should see something like this near the top of the file: ![]() OBJ files are also text readable, so it’s worth checking they have the correct pathing to your MTL file. Make sure the MTL file reflects this pathing like so : Typically it looks something like this:Įach of my OBJ files is set to use the same material (doesn’t really make a difference, but neater since they all use the same palette), and the texture file is located inside the texture folder. ![]() To start with, I like to make sure everything is in a nice folder structure that I can simply ZIP it at the end and upload. Not to worry I’m sure we can figure it out!įrom the lack of texture and animation, it sounds like it might be a path related issue in one of several places, so I’ll just go over an example of how I have things structured for my own TimeFrame animations: ![]()
