I have been experimenting with the high res areas in google earth and attempting to bring it across to unity. Of course you can import to via sketchup but if you import the whole course you lose the vital detail. Importing small areas is possible but you then have many overlapping meshes which for the life of me I cant merge together. If there was a way to do this efficiently it would be a huge resource for the community with many parts of USA included. Has anybody had any success with this?

See attached for the level of detail within GE

Happy Golfing

I have been using Sketchup to import better detail in the terrain and image's to unity, but you will need a few other programs to to import a single mesh to unity, and also Photoshop to to merge the images.

This is an example of several overlapping mesh's.

Here is the single mesh made from the above mesh's

And here is the image made from Photoshop

If I get some time today, I will try to make you up a tutorial.  It took me quite some time to figure this all out.

CourseForge will only allow the drawing out of fairways, greens etc on Unity's terrain, not meshes, so you'll need a greyscale heightmap for Unity rather than a mesh.

I just had a quick go with Sketchup and was getting a 2m mesh resolution at small capture areas (much better than I expected from Google, but it was a well surveyed area), but there's no way I'd have the patience to do the whole course like that. Surely there's some free program that saves you doing all that?

The mesh can be transformed into the unity terrain using "object2terrain" plugin as described in this thread http://www.perfectpa...ogle-sketchup/ 

which will make it a height map.

Probably Terrain Forge will do all that, but that program is not available for us to use, so in order to get started using unity, This was about the only option I found to get real detailed terrain data into unity. If you have overlapping meshes, You will need a program to drape the mesh to make it one mesh. At that time you can control the size of the distance of the grid. And your right, It takes a lot of patience.

I believe PP are still intending to release their Terrain Forge tools when the game is released.

Jimbobh that would be a massive help. I see you are using meshlab to merge the meshes. I am downloading it as I type.

I look forward to your tutorial and appreciate your help.

[shimonko]

Terrain Forge does eliminate all of that and will be easy for the more savvy, but in the opinion of myself and the other person testing it, still needs a few things simplified for public use. 

Not that it helps here but may be of interest to anyone reading, Google Earth Pro became free yesterday.

[slewin]

What does GE Pro provide anything of interest for us designers

[shimonko]

I used GE for creating a 360° panaroma for PG, however I never subscribed to the pro version so I was limited in resolution. Now having free access to Pro allows higher resolution panaromas.

I didn't actually use Mesh lab to merge the meshes. I used that program to clean it up and reduce the polygons during my first attempts at making a terrain.

You can try this tutorial using Rhino3d https://www.rhino3d.com/

I changed the auto spacing to 1

You will then have to add the object2terrain script in your unity editor. http://wiki.unity3d....=Object2Terrain

Depending which version of unity you have. I am using v4.3 so had to use the c# script.

I haven't had time to make up my own tutorial but this might help. If you want to send me the location of your course, I could try to get something working for you. Might get you by until the real tools come out.

Jimbobh,

I am thinking of having a crack at Oakmont CC. Not sure if you were a links player but I did a recreation many years ago for links and I think it would translate well with PP.
If you could list some simple steps I could probably get my head around it.

Heres the address

1233 Hulton Road, Oakmont, PA 15139, United States

[Jimbobh]

slewin,

I have gotten this far, hopefully it's the right course, lol

Oakmont CC in sketchup

Oakmont CC in Unity

let me know if it's about right and I can send the files to you.

JB

Wow Jimbobh,

Is there any other Oakmont!!

This is great and will saving me a lot of dicking around. I would love the files when you get a chance.

One very appreciative designer

You can email me here if needed:

Cheers

Jim,

I have received the files. Thanks again.
It is now imported into Unity but the terrain resolution seems quite low. Any tips on how I can increase detail?

[Jimbobh]

you will have to adjust that in your terrain setting in the inspector under resolution.

I set mine like this:

height map at 2049

Detail Resolution 2048

Detail Resolution per patch

Control texture 1024

Base texture 1024

I think everyone uses different settings so you might have to search the forums and experiment.

[shimonko]

And if you mean the terrain overlay image is low resolution, click on the texture in the Assets window and change 'Max Size' to 4096 and 'Color' to 16 bits or Truecolor.

[Jimbobh]

I only used the higher resolution images on the actual course area, the surrounding images are a low resolution. I did it that way just to save me some time, The mesh had about 190,000 polygons that I had to reduce down to 65,500, just under unity's maximum. don't know if that matters or not, but at least you can play with it until they release the real tools.

[slewin]

Jim,

Is it possible to get access to your detailed mesh for Oakmont before you reduces the polys. I would like to fool around with it before exporting to unity.

Thanks

[Jimbobh]

I have actually been working on a new terrain for Oakmont that will Hopefully give you better terrain detail with a higher resolution image, I Stitched about 160 images and terrains from Sketchup zoomed all the way in. Photoshop wasn't able to merge the inages so I have been doing that one by one,

The image still needs a little adjustment.

 

I'll get it done as soon as I can. Jim

[slewin]

Jim,

I will be forever in your gratitude.

 

Hopefully I will get my head around this stuff and be able to handle it myself. I have managed to get a pretty detailed mesh from rhino using drape but when I convert to terrain I lose alot of detail. Are you using Rhino to Drape a mesh?
