Hi,
In order to see/write on the other partition you have to format it on fat32, if you have ntfs, you obtain read permision only.
But I read that the boot camp is for time limited, do you know when that ends?
Or, if I missunderstood, Can I use it forever?
Thank you in advance |

All I know is that BootCamp is still in Beta. That might be true about the different formating hrmm. Anywho I wouldn't touch BootCamp at all till they get some of the bugs worked out, not that I care about running it at all.

| And some of us still work on PPC Macs/won't buy Windows at gunpoint, so it would be nice if the discussion left at least something for the lowest common denominator. |

Many game engines (like Ogre, 3D Gamestudio, Beyond Virtual) read heightmaps to generate terrains.

*beats a dead thread into the ground*
Am I to understand that Unity doesn't support Heightmaps? I could swear I heard someone reliable (Nicholas) mention that heightmaps were treated like bumpmaps. I still have yet to see that work, (or any heightmap-like function work) in Unity. I have seen that an import setting can turn a greyscale heightmap into a normal map, but that's about it. ...have never seen that turn into a 3d surface of any kind...
Could someone settle this? I'm sure some of us would rather spend 10 minutes in L3DT than spend 10 hours in 3DSMax just to create tests or random land...
Heightmaps? Anyone? Have I lost my mind?

That's a matter of reading the heightmap and generating the 3D object using the mesh programming interface. One of the procedural examples (from this page) even has code that does exactly that, so all you have to do is use or adapt that code.
Edit: Ooh, posting at the same time is fun!

Alright... Obviously Heightmaps are possible in Unity, and are probably easy to do for every other normal human being, but after two days of trying everything I can, I still cannot seem to make a heightmapped mesh from a greyscale heightmap.
Here's what I'm doing.. I open a new project, import the generate heightmap script from the procedurals folder found online, and attempt to apply it to anything, just to try to duplicate what happens in the generateheightmaps.unity project. I've tried applying it to an "empty", to a plane, to a cube to other meshes... I looked at the script to see what I could be missing, but I just can't seem to figure it out. So what's the secret? Does anyone know how to use this script, or just how to make a heightmapped mesh?

Yep, you apply the script to an empty, and it generates the mesh from a heightmap wherever the empty happens to be located. You have to drag a heightmap onto the "Height Map" slot on the script, and give it a material. You can also change the size by changing the appropriate variables. Are you getting any error messages?

Any luck?
Now what about this...I have heard that big titles/studios use procedural terrains for their games, probably because of performance. Is this true? has anyone reading this been part of a commercial title that has done so? If so, my question is this: How do you position other objects in 3d space when you dont have a reference for its transform .position? Id like to use this heightmap method, and find out how to make it generate procedurally, endlessly, but if you cant see it, its hard to work with, unless things just drop randomly into the level...
Thanks for feedback
AC

Most high-end games don't procedurally generate their worlds. They have artists for that (and lots of them)
They might use procedurals for smaller details (where are there bushes in this forest), but they don't wanna lose the ability to level-design.

Raycasting...see where the ray intersects the mesh and put your object there.

Yes. I am getting error messages when I try to apply the script to an empty. I am glad to hear you confirm that workflow; I thought that was how it went! What happens is an error message pops up telling me that I cannot apply the script to the empty because "you need to fix all compile errors in all scripts first". This is happening in a new project with only a point light and basic camera added. hmmm...
On another new project, the script would not apply to the empty. I renamed the object from "game object" to "empty" it allowed me to apply it. YAY! Now to get a mesh collider to work! Harumph!
Maybe I should stick with trying to build the mesh in a 3D app...
Nicholas, you and your darned work ethics! I believe you when you say the way others do it is with artists, and I believe that's ultimately the best way to do it for those that have that ability. The cool thing is in some world builder apps that only generate heightmaps and textures, you can still have a pretty fine detail of control of how the maps end up being laid out. My ultimate goal in all this mayhem is to figure out how to actually use what those cats offer (Freeworld, L3DT, DeleD, etc...). If their programs are actually useful in Unity, that might make some goals happen much more quickly for some...
There might be some major thing I'm overlooking here, too. So far, I haven't gotten past the basics yet, though (e.g. collider on the heightmap generated mesh, etc...).
