パラメーター
| texture | The volumetric texture to draw. |
| opacity | The non-linear volume opacity modifier. Use this to control the opacity of the visualization. Valid values are 0-1, inclusive. A value of 1 is fully opaque and a value of 0 is fully transparent. The default value is 1. |
| qualityModifier | Sets the sample per texture pixel count. Higher values result in a higher quality render. The default value is 1. |
| filterMode | Sets the texture filtering mode to use. |
| useColorRamp | Enables color ramp visualization. |
| customColorRamp | The custom gradient that Unity uses as a color ramp. If this is not specified, Unity uses Google Turbo color ramp. |
説明
Draws a 3D texture using Volume rendering mode in 3D space.
Teapot volume rendered with a gradient that has a transparent black outline.
Noise volume with fire gradient applied.
