I added some of the Fx Spider Web Corner Kit and Fx Spider Web Wall Kit.

They are not showing up when I play through the level. Is there something special I have to do to their properties or maybe a certain graphic setting I need to have on?

Thanks for the help.

I've had that happen with webs playing unmodded Skyrim. You might find quitting to the main menu and reloading fixes it?

I have reloaded the map and that didn't fix it

do you have a ton of FX in the map?

all fx objects have performance tax and have a limit to how many can be rendered in a cell at once.

If you mean that they just don't show up very well...you can set their emittence to a light object and they will ignore the ambient lighting in your cell and display the colour of the light you selected. Double click and look for emittence tab.

It's probably this.

If you have 6000 fx in your cell and no roombounds, they wont show up because you go over the hardlimit. Place roombounds or back off the number of FX and they should reappear.

Make sure the webs are oriented correctly, as I think some are directional (only 1 surface is visible). There are a few games objects that are like this...
