Landscape creation problem

Zocky

Hello!

I was playing around with the new landscape feature, and while i could create new landscape without heightmap, i have problems creating landscape using heightmap. The "create landscape button" just isn't highlighted.

So first things first, maybe problem in texture itself.
So, lets say in Photoshop cs5, i create new black-white image, 2048x2048.
I then go to Image->Mode->Grayscale. Also, in same menu, i switch to 16-bit per channel.

I then choose save as, and select Photoshop RAW (*.raw), and the window is opened with some settings.


What are the correct settings here?

Anyhow, back to UDK.
I click on Landscape button, i get this settings. I load my hightmap, set these (or any other that the documantion says), and the button is still dissabled:


So, does anyone getting, what am i doing wrong? Probably something to do with heightmap i'm guessing?

Oh btw, since we are speaking of landscapes, when you use texture layers, can you only use 3 or can i use more then three?

Cheers,
Zocky

You want to set it to IBM PC in the Photoshop export, then grab unsigned and PC in the UDK import. As for layers, I think you can use 4.

Tnx, will try. And in PS options, what does the "header" number mean?

AlexLeighton

It adds bytes as placeholders to the file before the image information. I have no idea what you would use this for, probably someone on here knows, but just leave it at 0 for making heightmaps.

I have the exact problem, i did all the above and still the Create button is disabled, any ideas?
I'm using latest version of UDK.

Thanks!


Edit: Also, when i import the heightmap in UDK it sets the size to 1024 X 2048, but in Photoshop its 1024 Square

I could be totally wrong on this, but I believe it may be the size of your texture?
Recommended Landscape Sizes

I don't know if that's only for when creating a Landscape without importing a heightmap or not. But maybe try one of the listed sizes and see if that helps.

Thanks, i resized the texture to 1009 square and its the same problem. I managed to get a 512 square texture in .r16 format, and that worked out, i think the .RAW photoshop exporter isn't working right. Does anyone know how I could export large .r16 format images?
The free edition of World Machine restricts me to 512.

I just tried it in PS CS3 and had no problem using the recommended sizes from that UDN link.

16 bit Greyscale .RAW - PC byte order - 0 Header.

Recommended Landscape Sizes is - 512*512 or 509*509 . 1024*1024 or 1009x1009? Be or not to be ? :poly121:
