This article describes how to set priorities for loading parts of a 3D model. This helps if a model cannot be fully loaded due to insufficient VRAM.

Setting priorities for loading model parts

You can set high priority for loading some model parts. In the 3D view, parts with high priority are loaded before parts with normal priority.

When you set a priority for a model part, this takes effect the next time the model part is loaded. It is handy to save the priority settings in an appearance template, as they take effect every time you apply the template.

To set priorities for loading model parts:

1. In the Revizto application, open a project.

2. At the top of the application window, click 3D.

3. On the top toolbar, click Object Tree .

4. Right-click an object and then do one of the following:

   • To set high priority, click Require.

   • To revert to normal priority, click Unrequire.

   High priority applies to the object and all its subordinate objects. Applying normal priority to an object that has a parent object with high priority has no effect.

   Names of objects with high priority are displayed in magenta color.

   

Best practices

If your 3D model is too large and some parts of it cannot be loaded because of insufficient VRAM, we suggest adding the following rules to the home appearance:

• "Require" for loading outer model parts (such as outer walls, windows, and roofs).
• "Unrequire" for loading inner model parts (such as inner walls, ceilings, and stairs).

Use search sets to select inner and outer objects.

As a result, Revizto will load the outer objects first. This will provide a complete panoramic view of the 3D model. Then, if Revizto still has some free VRAM, it will load the inner objects. If you zoom in or create a section box, the skipped inner objects will appear.
