Garment Collision with Cache

Functional Description

1. Support collision with recorded garment cache during garment simulation

2. Support garment cache collision with UE objects

Operating Instructions

Step 1: Setting up the Garment Collision Box

Setting the convex collision box for the Garment Static Mesh Actor (this step can be skipped when the collision type is Not Convex)

Step 2: Setting the collision type in the cache

First, ensure the apparel is in Garment Cache Play mode and that valid cache data is configured.

Setting up cache collision:

Collision Type：

• No Collision

• Box----Bingbox Collision

• Convex----Bumpy Collision

• Triangle----Vertex Mesh Collision

Collision Drawing ：

Used to visualization of collision bodies in play.

P.S. Triangle collision type not supported yet; more performance-intensive

Step 3: Setting up the collision object in the solved garment

1. The solved garment character is set in Garment Simulate or Garment Cache Record mode.

2. Check in the solver properties Collision Convex

3. Select the garment cache involved in the collision

In Obstacle Garment Obstacles, use a straw to select the Actor that will be the collision actor in the scene.

4. Click Play to generate a collision and solve it

Common Issues

1. The collision effect between garment and cache in Sequencer is poor, resulting in penetration.

You can increase the frame rate of Sequencer to improve collision effects.
