| # Morph-Primitives Test | ||
|
|
||
| ## Screenshot | ||
|
|
||
|  | ||
|
|
||
| ## 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. | ||
