Edit/remove culling distance for translucent materials

Hi all,

Does any one know how to edit or remove the cull distance for translucent materials.

I have a portal with animated faded edges that I want at a distance (~1000mtr) from the players start position and they gradually make their way towards it over the course of the map.

It is supposed to be visible for the entire duration. There is a smaller solid mesh/opaque in front of it which is visible throughout the journey but the portal is not visible until the player is 100 or so meters away.

I have tried LODs, different shading models and a few other material tweaks as well. Its not possible to model the portal effect as its animated and based on a noise pattern.

There is another post in the UE forums which talks about a few things and I have tried but to no avail. I understand there is a performance cost but it is important to the story of the map.

Thank you for your time.

Did a dodgy workaround and extruded a long thin poly from the portal mesh that runs under the floor to the start of the map. Now visible from 1k away.
