Mapsize larger than 4096 ?

[mbot]

Are there any plans for the feature to export map sizes larger than 4096? If so, when could this happen?
Thanks for infos *btw best terrain editor i know :D*

I am still not sure about sizes greater then 4096.
Carrara has problems with greater terrains and the rendertimes in Terragen are highly increased.
So it depends a bit on the devleopement of the rendersoftware. If TG2 will be better with great terrains, or Carrara, or may be Bryce, it would be no great problem.

another problem will be the ram. Working on 8196er terrains will need close to 2 Gigabyte ram. Most user have as maximum 2 GB, but you would need more, XP also needs some memory.

You see, it is not sure and depends a bit on the "others".

Have to wonder about TG2 sense the terrains will be procedurally biult within but heightfields can be imported and mixed with the procedurals so even using the 8196 will still be a very tiny local terrain as opposed to an entire procedural heightfield planet for example. Terragen's current largest size is 4097 equaling to 15,099.49 sq kilometers so 8196 would be around 30,198 sq kilometers. The total surface of the earth is about 509,917,870 sq kilometers. That is insane and one huge heightfield map.

I think, the resolution is dynamic. That means, it depends from the distance of the camera.
A imported terrain with 4096, may be intern only calculated with 512, when it has a greater distance to the camera.

Well... for my project, I need to use a terrain larger than 4096x4096. While I could just work on it in 4096x4096 chunks, that'll leave seams between them. I need some kind of a solution to make them not seam, and still look natural and continuous. A 8192x8192 height field isn't logical, due to its memory requirement.

This is a feature planned for version 2. It will be similiar to a crossfade of wave editors. This will enable the user, to combine different terrains seamless.

So far, small seams may be visible in close ups, when you cut a 4096er terrain into 4 terrains. But this seams would be very very small, when you take care, not to change the border, where the terrains meat.
