+# Morph-Primitives Test
+
+## Screenshot
+
+![screenshot](screenshot/screenshot.jpg)
+
+## Description
+
+This model contains a simple mesh with two primitives:  A larger red primitive displays a grid covering 3 of the 4 quadrants of the model's area, followed by a smaller green primitive covering the last quadrant.
+
+Each primitive has a morph target that creates an elevated area within these quadrants.  The model's only mesh contains a `weights: [0.5]` instruction that should cause these morph targets to be applied at half strength, raising the center of the model as shown in the screenshot above.
+
+## Common Problems
+
+If the entire model appears perfectly flat, it is likely that the morph targets have not been applied as requested.
+
+If the red area or green area is missing, particularly in the Draco-compressed version of this model, it could indicate a problem with decompression or with support of multiple primitives within a single mesh.
