Heightmap Help

[Skhorn]

Hi,

I had been experimenting with the heigtmaps, following this guide https://wildfiregames.com/forum/index.php?/topic/20786-palaxins-heightmap-guide/, but i'm struggling with the ocean-floor, as i cannot modify it to make it deeper in Atlas (Units can walk over it). As what i have read i need both topography and bathymetry to use the script that Palaxin provided to increase the ocean-floor.

This is my result

The original image i used

After several tries while croping, scaling and importing in atlas to see the results, this was the final

So, how can accomplish a deeper ocean? Do i strictly need topography and bathymetry to accomplish this? Or there is another solution?

 Can someone remove this thread? I already found the solution

@feneur

@Skhorn are you sure?

[Skhorn]

I'm sure

What did solve it?

[wowgetoffyourcellphone]

My guess is he increased the total lightness to make the black grey, then re-darkened the deeper ocean parts.

We are currently discussing this at a PM. I have problems also with the ocean floor.

[wraitii]

I believe the solution was that water height is a separate setting in 0 A.D.? 

[shieldwolf23]

The one I got has a default setting of 5 when viewed in Notepad++. Low elevation areas in the real world are represented as shallow waters in Atlas.

Height range solve it

Yes, that was

[niektb]

Oh, I thought that the problem was that black (#000000) did not give enough depth...

[shieldwolf23]

I guess that it all depends on how the image is generated the first time. When I followed Palaxin's guide, and merged it with the straightforward source from Skhorn, the water depth is not enough to make the ocean deep. I guess that either (1) settle with a land mass with lower mountains or (2) manually edit the ocean to give more depth.

Guess the idea is not to manually edit the map to get more ocean deep

@Skhorn Just in case you didn't check these links already:

http://trac.wildfiregames.com/wiki/Atlas_Manual_Heightmap_Import

Also there is a nice topic in the forum:

 

[Skhorn]

 I checked them, i forgot to use the height range with color contrast

[shieldwolf23]

@FeXoR - I followed the guide (beginner level) to the letter, and here's my result. You can see that the water level is shallow.

Here's what I did, using Brightness contrast

output levels - 5

All Channels - 100

then, gaussian blur - 4

The water would still be in the same level, but land would be higher. I can now edit the water level via Notepad++, and use 80 to finalize it.

@shieldwolf23: the water height is a setting in Atlas, so you can raise it or lower it.

[shieldwolf23]

I know man The 80 I'm talking about is to be precise, since I'm bad at estimating, and well, it's easier to use Notepad++ editing HTML.

[wraitii]

Ok just wanted to make sure

I think your problem is that the height map is 16-bit and the usual image is 8-bit only.

[Skhorn]

darn, i wanted to start mapping, but wraitii insistence about the 8-bit height map made me start to find a solution for that  guess i will try to use your script or come up with one. 

I'm happy with the result i got after modyfing it (But i got my doubt about those mountains, more blur it will be), but i will give it a try to that 16-bit to 8-bit process and see what happens
