Got a problem or need advice?

I notice that when you import an heightmap, the brightest point on the map becomes the max altitude.
Is there a way to prevent this, so that solid black becomes the lowest altitude, and solid white the max altitude?
Reason being, we've got a nicely designed heightmap of a world, but we want to split it into tiles first before importing into L3DT for it to do it's magic.
Any any point during the development, a tile might be updated, so naturally it's more time efficient to only reprocess that tile.

Hi Piratelord,
Okay, I'll put this on the to-do list.
Cheers,
Aaron.

Hey, that's great. Should be fairly simple too?

Hi Piratelord,
Having implemented and tested this mode, I've decided to make it non-default and to have the option to enable it in 'settings->local settings', rather than in the import interface. The name of the setting in Local settings will be 'File->import->Image->UseFullGreyscaleRange' or somesuch. This update might be released before Christmas, but probably in the new year.
Cheers,
Aaron.

Sounds great and will be a big help.
We have a large map, which I export into sections for L3DT to produce better looking mountains and the like, and the results are then pasted back into this original heightmap and tweaked.
Being able to then re-import this heightmap into chunks and not worry that the max altitude is wrong for that chunk will be a big time saver.
Thanks for this.
Just gotta work out some way of being able to provide a 16bit image to L3DT when I've finished

Hi Piratelord,
On the downloads page is dev build 2.4.2.21, which includes this mode. I've done this rather quickly though, so the process to activate this mode is a bit more involved than it could be. Firstly, you need to import an image as a heightfield as usual. The, go to 'Settings->Local settings' and dig down to the flag at 'File->Import->Image->UseGreyscaleRange' (or words to that effect.) Double-click on that setting to flip the state. Then, go back and re-import the heightfield and it should work.
FYI, the reason you have to do the import twice is that the flag is only created when the importer asks for it. However, once it's been created, it is remembered across sessions, so you only need to do this process once. If this proves popular, I’ll come up with a nicer interface in a later release.
Cheers,
Aaron.

Hey, that's great. I'll test it out right now.
We are importing a bit atlas terrain into TSE as small tiles, at the moment I can see the join where the calculated altitudes for the terrains are slightly out (still very close though).
I'll let you know how it goes.

Seems to work a treat! Very useful function, and not really that clunky to change settings.
Great work Aaron. Gonna have to buy this.

Just to say that I will find this useful too.
