As far as I can tell, everything being rendered here, is on show, and therefore nulling it would make the scene look daft. You can null all you want, but you won't get the same looking scene. I think the only faces you could null without noticing, would be the outside faces of the rubble, and that isn't being rendered from anywhere that frame rates matter anyway.

I'm pretty damn sure they would be rendered...they are not sealed away by VIS in any way so the majority of the map would be rendered at all times. I'm with Reno in the thought that only the furthest and outer most edges of the chunks could be NULLed. Why not vary the sizes of the platforms? so some 3,4,5,6 sided ones to mix it up.

By regular sized steps Alien_Sniper, I'm assuming you mean the jumbo steps used in most DM maps, ones designed for clowns, with extra length to allow for the big shoes.

On a serious note that would likely make more polys and also require serious altering of the map. So thanks for the wonderful suggestion, but perhaps not.

Its not hard to change the stairs, but they are currently at the right combined height, width and length. If I was to change that, I would then have to alter the parts of the map they are connected to, to ensure that things lined up. Then the spacing between the parts would have to be changed to suit the new sized segments. Its just a bit of a hassle I don't have time for, particularly when the stairs are fine and its not really going to make a noticeable difference in the R's.

Anyway, I have deleted some of the smaller debri which has decreases the R's to no higher than 1250, which I figure is acceptable, without ruining the effect.

I know this ain't the editing forum, but to save time I'll ask it here. The jump pads are causing some trouble. Most are directional, as opposed to the standard straight up in the air jump pad. But as some might know it causes problems. I use two pushes, one that pushes you up and into the other that pushes in the right direction. This means they only work if you jump at them from the right spot. I you jump from above you hit the directional push which throws you off the map. Does anyone know how to get them to work without the need for two pushes, as its the only remaining major flaw in the map. Thanks

Apart from the bounce pads everything is ready to rock and roll. I tried what you suggested Fishy, but it didn't work. no matter how much fiddling around I did it would only push up, down, or 360 on the x axis. The bounces as they are a bit buggy, not always delivering you to the desired location. I'm still using the method of two pushes, one that pushes you up and into the other that pushes in the right direction. If anyone knows exactly how to do it, or a tut that could tell me how, I'd be forever grateful. Thanks.
