LOD Recipe: Morph targets ​

Keep morph targets in your LODs using the Allow Morph Targets window in LOD Recipes.

Prerequisites:

  • A LOD Recipe containing at least one Skeletal Mesh that have morph targets.

1. Open the Allow Morph Targets window ​

The Allow Morph Targets window is visible by default at the bottom of the LOD Recipe editor. If it's not, you can open it from Window → Allow Morph Targets.

Click on the name of a Skeletal Mesh to view a table view of what morph targets it has available.

2. Check the desired Morph Targets to keep ​

First you need to check Allow Morph Targets for each LOD you wish to keep morph targets for. This will make the checkboxes in the table view editable. Then, check/uncheck what morph targets you want to keep for each LOD in the table view.

3. Build ​

When you're happy with what morph targets to keep (and the rest of the LOD Recipe settings), press Build and wait for it to finish.

4. Result ​

Figure 5 and 6 shows the resulting mesh and the morph targets "Joy" and "Sadness" for LOD 0 - 3. The result is created using the morph target settings seen in Figure 4.

Figure 5: The morph target "Joy" set to 1.0 in the Skeletal Mesh editor visualized for LOD 0 - 3. The morph target has been kept for LOD 1 and LOD 2, but not LOD 3.
