Topic: Terrain - Map vs. Object

[ToFi]

Hi,
I created a test terrain. Test intention: To see the difference between an imported terrain and the map version of the same landscape.
Once I imported the object and once the map.
That doesn´t fit at all. What is wrong? Tipps would be cool.

P.S.: The cube is 600m to see the relations
The landscape is  5000x5000 m.

Hi ToFi, this (and many other questions) are answered in the Tips, Tricks and Shortcuts thread (Search for "Terrains in Lumion"):

Morten,
I saw that tipps before making the scene.
The resolution, the height-32bit-rgb-600m-0-3 concept ans so on.
Don´t see that the solution for my issue can be taken out of that terrain tipps.

P..s.: I just saw that the width of the terrain should be max 2048m.
Retry it with that measures.

As the post explains, the Lumion terrain is 2048x2048m by default and there is no way to scale it up/down along any axis (this has been requested before). You can import your own terrain mesh if you need a bigger or smaller terrain size - simply apply a Landscape material to it to be able to paint on it.

Hi Morten,
with the model in 2048x2048 the map version and object fit. Except the height.
In the tipps you can read following:...RGB 0 to 3.0 in Photoshop = 0m to 600m in Lumion

How can I push the 32-bit depth map to 3 in photoshop?

1) Image -> Mode -> 32-bits per channel

2) Colour picker -> 32-bit value -> R: / G: / B:

Sorry, don´t know that workflow...

You mean that window?

Or the colour pickers here?

[Morten]

2) Farbwähler -> 32-bit-Wert -> R: / G: / B: -> More than 1.0

Hi Morten,
I´m familiar with Photoshop. But I do not understand what you mean with your, for me, cryptic workflow.
Chris, the PS-special-agent in our agency do not understand too...

best regards

Well, the reason it may sound cryptic is that it's actually rather difficult to edit a 32-bit heightmap in Photoshop. Anything above RGB 1,1,1 in the Farbwähler is pure white

As you saw in the Tips, Tricks and Shortcuts thread, you can boost the white color in the Farbwähler from 1,1,1 to up to 20,20,20.

32-bit texture in Lumion:
0 - 1 = 0 - 200m
0 - 2 = 0 - 400m
and so on...

Unfortunately, I am not a Photoshop expert, so I don't know if there's a way to scale the high dynamic range, so that the pure white (1-20) spectrum would be visible on a regular monitor, or indeed, if there is a way to convert an existing heightmap to the 1-20 spectrum.

Needless to say, the developers are aware of the fact that this makes it hard, if not impossible to make a heightmap in Photoshop that goes beyond 0 - 200m.
