How can I generate a heightmap in Wilbur with predefined contours and rivers?

[jokull]

Hi all. I'm trying to create a more in-depth heightmap than what I have for a big conworld project I'm doing with friends. We have a world map we've been using for a long time with terrains marked on it, but it doesn't go in depth as much as we'd like. Here's the current map:

Attachment 83035

I can turn that into a grayscale heightmap very easily, but when I do, the expected behaviour is that it will create flat areas at each contour instead of sloping up. However, I want to generate slopes between the contour lines as well. Is there any good way to do this in Photoshop or Wilbur? In addition, is there a way to feed already existing rivers into the erosion filter or something? Thank you!!

Here's the full map, by the way. We put a lot of effort into this.



Thank you~

I managed to figure out that the deterrace tool existed, and a combination of that and the Gaussian Blur tool is working wonders for me! I'll let you know if I have any more problems (and I'll be sure to post a final link here~)

easily ? that is the question

I think you will find that about 90% of your starts will end up in the trash.
At least for the early part of the learning curve .

the developer "waldronate" starts with a black ( 0 ) and white ( 255) only image

me i start with something more detailed and use wilbur to erode the surface

I tend to use three or more masks and a multi resolution technique these days. Predefined rivers may make up other masks. Better inputs can give better outputs. I keep trying to find a minimum level of input and time to get plausible results.

The main difficulty for me was the contours; the deterrace tool solved that problem. I'm having to use masks for rivers + lakes, but it's all good! Thanks for your help!

i use a distance transform on the water ( ocean and river ) mask , then move the gama point and get something like this


i mix that with the mountains ( extracted from your image in the first post)


this gives me river valleys

and i end up with this ( 8 bit copy of the float and only 2048x1024 )



this is a quick low iteration low resolution
