Model Simplification Tools

There are a number of tools in the Graphics Gallery to manipulate imported models.

These tools are found in the right-click contextual menu of a Graphics Gallery or graphics node in the Explorer panel.

The following model simplification actions are available to all users of Vortex® Studio Editor:

Remove Orphans

Evaluates the contents of the Graphics Gallery to find objects which are not referenced within the Graphics Gallery. No graphics nodes need to be selected; this action works on the entire Graphics Gallery. From the resulting pop-up window, you can select the orphan objects you want to delete, freeing up memory. If you want to remove all orphans, it may be necessary to repeat the procedure multiple times until a "No orphans found" message appears.

Bake Graphics Node(s)

If the model includes transforms (rotation, scale, etc.) that are not as expected, it is possible to return the model (local transform) to its identity matrix without affecting the aspect of the 3D model. The local transform is set to identity for each selected node and its child nodes, and the associated geometry is updated to respect the aspect.

Merge Graphics Nodes

If the 3D model includes too many graphics nodes, it is be possible to merge them without affecting the aspect of the 3D model. This is useful in situations where there are many small pieces that do not need to move independently and can be handled in a single draw call. You can only merge graphics nodes with identical materials. In the case where the merged nodes have different graphics materials, a new node is created for each different material. When merging nodes, the resulting node is transformed so that its pivot point is at the same location as that of the last selected node.
A bake node operation occurs during the merge node process.

Set Transform to Center

Sets the pivot point of the node to the center of its bounding box.

Set Graphics Node Transform

Sets the transform of the node to be the same as the transform of the source node, which is selected in the resulting Set Node Transform window. The underlying child nodes and geometries are also adjusted so they visually remain at the same location.

Change Mesh Orientation

Reverses the index order for each of the node's polygons.
