[Released] RaindropEffect

RaindropEffect is a drag & drop solution that create a very realistic looking raindrop effect on full screen or windshield glass object with a couple of clicks. Raindrop can fall down and leaving a small trail. Raindrops that are close to each other can get merged. Raindrops have refraction effect. It can simulate glass foggy. Raindrops and fog can also be wiped off dynamically.

Hello, Does this have capability to change direction with changed vector or velocity?
Like wind hitting the sides of glass as a car is moving and changing direction. Example is aircar vr.

This asset does not support this feature at the moment, but it is planned to be developed in the future.

The new version v1.3 is live. It supports changing the direction of raindrops dynamically.

v1.3

  • Supported changing direction of raindrops and trails dynamically;
  • Optimized the effect of raindrops and trails;
  • Added 3 types of rain scenarios in the example scenes, including: light rain, moderate rain, and heavy rain;
  • Updated the document;
