The U and V dimensions represent the vertical and horizontal axes of the piece of paper in the same way that X, Y, and Z represent the three-dimensional axes of a 3D model. To visualize the concept of UV unwrapping, imagine cutting out every surface of a 3D model and placing those surfaces flat on a piece of paper. You can skip this step if your model has only one color. When the number reaches a value that matches your performance goal and looks good, select Apply. You'll see the Tris value in the bottom right of the Blender window decrease as you change the ratio. For example, a value of 0.5 reduces the original polygon count to 50%.
This setting determines the percentage of polygons (triangles) that are removed. With the model selected, change the Ratio value to a number between 0.0 and 1.0. On the Modifiers menu, in the Add Modifier list, select Decimate. Select the model, and then go to the Modifiers menu in the tool column on the right. The example images below show a high-fidelity model that can be used when you're viewing one or two 3D models at a time on Microsoft HoloLens, and a low-quality 3D model used when you're viewing ten or more models at a time on HoloLens. This reduces visual fidelity, but increases performance. Decimation is the process of recomputing the surface polygons of the model to create a similar shape with fewer polygons. To reach application-specific performance goals, you might need to "decimate" the model. If it doesn't meet the target resolution, continue to the next section to decimate the model. If this number meets the performance target resolution, you can skip the decimation step and go directly to Unwrap the model later in this tutorial. Review the Tris count (number of polygons) at the bottom right of the screen.
If the 3D model appears gray, select the Look Dev shading option to show the colors.Ĭ. If the 3D model is extremely large or small, or hard to see, or is possibly off-screen as shown in the following graphic, you can use the mouse wheel to zoom the camera in or out until the model is visible. When you select Import OBJ, you'll see the 3D model with the imported materials. This imports the 3D model as one item, and searches in the subfolder for any materials. Select Import OBJ on the right side of the screen. Clear the Object and Group check boxes, and select the Image Search check box.ī. Select File > Import > Wavefront (.obj) to import the OBJ file.Ī. Right-click the cube, and then select Delete to delete it. When you open the app, a new scene is automatically created.

Overall steps for preparing a 3D model with Blender
#Blender 3d tutorials software
If Blender is the software that you decide to use to prepare your 3D models, review Blender's website and download the most current stable version for Windows. It supports the entirety of the 3D pipeline: modeling, rigging, animation, simulation, rendering, compositing and motion tracking, and video editing and game creation. What is Blender?īlender is a free, open-source 3D creation suite. There are other content-creation apps you can use to prepare your 3D models. Microsoft Corporation is not affiliated with, is not a partner to, and does not endorse or sponsor Blender or any of Blender's products. Your use of third-party applications is subject to terms between you and the third party. This document is created strictly for informative purposes to demonstrate how Blender works with Dynamics 365 Guides and Power Apps.
