On this step:
Secondly, If the map with static mask map, you should call "fow.InitMap()" function to set right mask width, height and mask data as byte array. The size of the mask diagram is the same as the size of the Projector's cookie texture. If the map without static mask map, you should generate mask data run-time.

is Mask Data was the alphaMap of Terrain Data?:
Like: terrainData.GetAlphamapTexture(0).GetRawTextureData() ?

i've tried fow.InitMap(128,128, terrainData.GetAlphamapTexture(0).GetRawTextureData());
and i got error:

IndexOutOfRangeException: Index was outside the bounds of the array.

sorry i'm still noob :' D
thank you for helping!

mask data 是什么数据？怎么生成的？
