你怎麽創造草?


如果你使用飛機作為地形,你將如何將草添加到飛機上並讓它像風一樣彎曲和流動。另外,你如何使草的顏色在綠色的深淺不同,所以你會得到黃色,幹燥的草叢。

最佳答案

這可以通過頭發粒子系統來完成。

  1. Add a hair particle system to your mesh:

  2. If you want to simulate the hair dynamics with realistic wind, you can use a Smoke simulation:

    1. Add a smoke domain object and a Smoke Flow object

    2. Add a Wind force field and a Turbulence force field (ShiftAAdd > Force field)

    3. Adjust the settings until you have a nice simulation (optionally add some collision objects) and bake the smoke

    4. Disable the Wind and Turbulence force fields for the particle system in Particles > Field Weights:

    5. Add a Smoke Flow force field and select the smoke domain object for the domain.

    6. Enable Dynamics in the particle system and increase the Stiffness

    7. Bake the particles, then hide the smoke domain and emitter:

至於顏色變化,您可以使用程序紋理
