Hi,
Lets say I want to render a heightfield for a texture. The heightfield is 10000m x 10000m, which is default setup when you start TG2.
Go to the Render Camera. Change the position to 5000, 10000, 5000. This will centre the camera on the camera, 10000m above it. Change the camera rotation to -90, 0, 0. This will make it look straight down. Click the Orthographic radio button. Click the "Use ortho width" radio button. Set the ortho width to 10000. This means that the camera will show an area 10000m wide, which is the whole width of the terrain.
Now go back to the renderer you want to use, lets say Full Render. Set the image size to be square ( 1000 x 1000 say ). This will give you a square image showing the entire heightfield. Uncheck the "Atmosphere visible" checkbox if you don't want there to be any atmospheric effects in the render. Hit the Render Image button and you will get an image rendered you can use as a texture, draped over a heightfield.
Obviously this is pretty low-res, with a 10000 x 10000 heightfield and a 1000 x 1000 pixel image each pixel is going to represent 10m. TG2 can't render particularly large images right now, I'm not sure what the maximum size is myself. I think it would be fairly easy to write something which would animate the camera across the terrain, rendering smaller parts of it at higher resolution. You would need to purchase the registered version with the animation module though. You could do it manually, if you were patient enough :-).
I've attached an image I rendered using the technique described above, except I did it at 640 x 640.
Regards,
Jo
