Digital Elevation

Lord. I just used this method to create a small maybe 1024 x 1024 map (terrain only.) and man was it laggy. Has this happened to anyone else?

That's weird. I made an 8016x4992 and only ran vbsp on it and it ran fine but thats probably
because I didn't run vrad. The displacements were 12 pixels apart (ie. I had 668x416 displacements)

Yes I got some kewl ideas now big dam wall with construction buildings and pumps at the bottom..

How did you get that SEXY sand thing texture?
My repeating rock texture thingies look like crap on a stick on a bun.

Anyone know where I can get DEMs for other places in the world?

How much does Dispgen warp the displacements from their original brush faces? I've never used Dispgen, but I have used a program called Disped and the problem I have with it is that most of the time it warps displacements from their brush faces too much. If Dispgen does the same thing, then I will continue to do my terrain work within Hammer. I like that if I think, "Hey, I want to open up this wall here and put a new path, I can efficiently cut my displacements to allow that without breaking the seamlessness of all my displacements.

I think a very good program has been forgotten, Terrain Generator,
it can be used to create displacements for several games, also for Source, EP1/EP2 engine,
info from the website:

About:

Nem's Mega 3D Terrain Generator is a relatively new terrain generator that takes a step in a completely different direction. Unlike traditional generators where the user must depend solely on the generators generation abilities, this generator gives its users complete 3D control over what their terrain looks like. Users start off with a flat piece of landscape, then add to it with one, or a combination of many powerful generation options. They then have several tools at their disposal to literally grab the terrain and pull it as they want it. The terrain can be saved as a .tgm file for latter use and exported to a .map file for use in any map editing programs for Quake engine based games such as Half-Life. Additionally terrain can be exported as a .t3d for use in UnrealEd or a .rmf or .vmf file for use in Hammer or any number of other supported formats.

Features:

* Full 3D control over the appearance of your terrain.
* Nine tools to help you shape your terrain.
* Fractal terrain generation via eleven unique configurable algorithms.
* Heightmap terrain generation.
* Multi level Undo, Redo and Revert.
* Four render modes: Textured, Solid, Wireframe, and Points.
* Several different styles of lightmaps.
* Lots of additional display options.
* Save your terrain as a .tgm file for latter editing.
* Exports to .vmf, .map, .rmf, .t3d, .dxf, .obj, .smf, .txt, .bmp and .jpg file formats.
* Ability to export hint brushes along with your terrain for polygon reduction in Quake engine based games.
* Texture browser.
* Simple vertex locking.
* Recent .tgm file menu.
* Quick and easy setup.
* 100% Free.

What i like about this program is that it's so easy to create landscapes and such, just with your mouse, OR with heightmap images.

Well the best thing you could do is making a displacement for the whole map using Terrain Generator,

Why can't I use

Code: Select all

anymore?

nice tutorial dude..
tnxs alot.. ;)

In reply to Nems terrain generator post.

I created a map with it but once i got it into hammer i cant seem to select individual polygons i have to select a massive square which probably contains over a 100 polygons.. ( tehre are about 10 or so of these squares that create the map)

Have you ever encountered this if so is there a fix?

Thanks

[jister]

thats your displacement being divided into nice squares, and there is no individual polys to select, there are only your displacement tools (you find them in the material editor)

nice tut D!
