Hey there again !
I want to surprise my friends company and create them a terragen render of their company logo.
Their logo is really simple text with a different font.
My vision would be that i sort of lift the logo from the ground and make it look like an island and it's surrounded by water. I have seen something similar somewhere.
So how should i approach making this ?
I have their logo on a huge png file without background, but if i try to use image map shader the text part of the image goes "below" the rest of the image. Hard to explain. The png is completely empty but the text still kind of falls inside the terrain when displacement is added.
tldr: So how can i create mountains from a png file that has a logo in it. A mountain with the shape of that logo.
Sorry for bad explanation, not a native speaker. :-[
You could make a 16-bit greyscale tiff of it, where the letters are white or a gradient of white to the black background, import it through an image map shader (Y projection and set its size), and attach it to a displacement shader, or the displacement input of a surface shader. If you also add a color adjust in between, you can adjust the amount of white and grey to displace the mountains. You can use the same image map shader (perhaps through another color adjust) to make a mask for colors.
I hope this helps.
EDIT: Here's a quick setup, one of the possibilities.
