 Re: Displacement troubles
Posted by amanderino on Sat Dec 2nd at 7:35am 2006

I decided the other day that I wanted to make a map using displacements so I could get better at making them look realistic (and I'd have some fun making the jeep do flips).

At first, my displacement was made from one brush and when I played the map I couldn't find where the jeep or the gravity gun had gone to. I checked my work again and made sure everything was correct. After seeing that it was, I reloaded the map I had created and searched for the jeep and gravity gun. I put on NOCLIP and flew through the map and I found the items inside a cliff that the spawn was on top of.

I looked through the forums and couldn't find any information about this, so I began looking through the sdk_ files in Hammer. I found the file sdk_vehicles and thought it would help me out. The only thing I thought I might've messed up was that in the original map I had done, I only used one very large brush. I made a new map but made the brush 1024x1024 instead of whatever huge number it was before. I get the same problem:

When I spawn in npcs and then kill them, the ragdolls fall through the displacement and land on the nodraw texture below. So far, I know that barrels, weapons, ragdolls, and the jeep all fall through but the player can't go through it without noclip activated.

Does anyone know why this is happening?

Displacements aren't real floors so to speak. You need to put a brush underneath where the player can walk in the texture nodraw iirc.

The player can walk on it and so can the npcs, as long as they are alive. My problem is that the jeep and other objects that have physics fall right through it. The map I am creating is like the Highway 17 chapter.

I think this is a bug introduced with one of the updates.

All physics objects fall though the displacements. I've heard of a trick in order to make the displacements block physics objects, but I'm not sure what it is.

Add -novirtualmesh to vbsp.exe

Do I place this in the expert compile options for BSP?

If you want an in-hammer fix, what worked for me was using vis groups to hide everything but the displacements, selecting them all, and then using the texture applicator's displacements tab to check "no physics collisions", hit apply, un-check it, and then hit apply again.

It worked for me, it might for you.


Also change the texture of the dock. Docks are rarely tile. -Facepunch

Okay. I figured it out. I added to the Parameter line instead of the Command line the first time around. Now that it's in the right place, everything works fine!

Thanks for the help everyone.

check out this thread. Same problem; same answer, with the detail you're looking for. Start from where Fishy responds in the thread...

Thanks Riven. Didn't help though. Seams it had no effect and judging by the responses in the other thread, I'm SOL.

Make sure you're using the expert compile option.

1. Press F9, and at the bottom left hand corner is a button that says "Expert..." You've now accessed the Run Map [Advanced]

2. Okay, now you'll see a table on the left, "Compile/Run commands"; make sure bsp is selected and on the right hand side, under the Parameters box, add "-novirtualmesh" without the quotes.

That should be how to do it. I stopped having the displacement problem after Hammer updates were released. I hope I helped.

You hope you helped your own question.....

Anyone else see the 'logic' here?
