Skydome with particle

Graphics
1

Hey guys i am working in one weather system,
but i saw one error in the shader of the rain,
when the particle is forward of the sky( skydome), her simply disappear
look one example,

1096×565 403 KB

note i am using,
particle/alpha blended - not modified
and standard / fade - not modified - for the sky

how i can fix this ?

thanks in advance

the second shader, set all values to white,

that you will see the bug

best regards :smile:
