This my 32k Earth-like planet texture.

I used real Earth surface textures and an imaginary continental map.

Have you ever heard of any software capable of creating HD Earth-like textures similar to this?

I mean only the terrestrial biosphere texture, without oceans.

If you mean randomly generating something that looks real but isn't, I don't know of any off hand...

Yes, I didn't want to write "procedural texture", because it should be permanent. But obviously it would be created by some random AND realistic method...

Thanks anyway...

Space Engine generates random textures, some do look realistic (you will have to search for worlds that fit your purpose) and you can export those textures from the program. But writing these textures takes some time and your graphic will think the program crashed, so this works for me only up to 4k I think. But on the forums they discussed ways to work around that problem. The textures created by Space Engine should even be free to use (but better look that up, I'm not sure).

I don't find those SE procedural textures very convincing...They don't seem to me very real. And 4k is far too low resolution for me...

you mean like this

John, these textures are not of standard size (2k or 4k).

Also, 4k is much better, and don't forget the normal/specular maps !

Those are very nice textures! But from a low orbit they don't look very realistic. That's why I made my 32k multilevel textures (bump+specular+nightlights too at 32k). At 32k you can see actual rivers, lakes, forests, even the signs of agricultural works...

Added after 7 minutes 46 seconds:
The view from 150km.

all those were created in Blender nodes and a camera view render

8ppd 2880x1440 is a good small testing size

so size is dependent on time and ram for the render

a 32 k would take hours ( most of the day ) to render

OK, but what about the details? What would we see at 32k?

In Blender i reset the camera and zoomed in







i render the Height map and texture separately

What you do paint on it. You can do another 32k layer with different procedural parameter being took up just the overlaid parts which meet the original landmass outline and erasing what is out of borders, e.a into water. Even on procedurals one could do a bit of photoshopping.

John, it looks surprisingly detailed! Is it possible to render additional details? I mean different features on the surface?

i paint on a sphere in Blender using the procedural nodes in feed back loops
then make it emissive and snap a image using the camera

OK, looks complicated. I use Blender only to build simple spaceships.
