rain

[Dreadlight]

Hi, new user to FCU. I am wanting heavy rain for a campaign in CoC. I have added the rain effect, but is there any way to not have it rain in the building/map using LOS? I have walls, doors and windows, is there such a setting as a roof???

First set a mask on the image, this will turn off the rain.

Then you can unmask areas (use the ALT key to freehand draw) to show the Rain, just don't unmask what you want indoors.

Here is a map, it's outdoors, but the principle is the same.

I've put a red box around the mask tools (click the image for a larger version). It's difficult to show the animated rain in a static image, but I turned up the intensity a bunch, everything except for the walled area in the upper portion of the image is unmasked, so the Rain shows.
