Scanned Height Map

[Valority]

Hi,

 

I've scanned a height map I found. But when I stamp the terrain and extrude, it looks like the attached image.

Is it possible to smooth the "bumps", while still keeping the mountains, hills... etc? Or should I scan/stamp the terrain in a different way?

@Valority This is usually caused by the color depth on the image, or compression on the texture import settings in unity. Please make sure that your original source image is 16 bit color depth or higher, and when you save the image it also keeps 16 bit colors. Then check on the import settings for the texture in unity that there is no compression enabled, you can check the import settings for Gaias own stamp images in the Gaia\Stamps folder for comparison.

@Peter The source image is 8129x8129 and 16 bit. When I import to Unity, I set it to these settings:

But the issue still persists.

@Valority Just to be sure: Your current target platform is "PC / Max Linux Standalone", correct? (Just asking since you seem to have multiple other platforms installed).
Could you please try to switch the "Format" in the Overrides for PC Mac & Linux Standalone tab (shown in your 2nd Screenshot) to "RGBA Half", or switch off the checkbox for "Override For PC, Mac & Linux Standalone" altogether.

@Peter Setting the format to "RGBA Half" fixed the issue. Thank you so much! 🙂

@Bryan, Thank you for the detailed tutorial. However, I seem to have some difficulties that I can't solve on my own yet, despite your previous explanations. Perhaps this is due to my inattention, but I really tried to figure it out. 

I have such sharp traces on the landscape that spoil the picture. If I start to align them with a brush, then everything will be fine, because there are enough polygons on the landscape. I used the height map and added it to Blender, adjusted it to the correct polygonation and did everything as it was in the video above, but in the end it still turned out what you see below.



While I'm running out of guesses what the problem is. Most likely, I just missed something important somewhere. Please help!

This could either be its to small compared to the terrain. 
You could use the stamper to use the smooth function / operation. 
Then smooth the whole terrain. 

Then you could use the stamper to add detail to the terrain. 

Its honestly hard to say whats happening without seeing it myself.
