adding terain to a sphere
Hi, I am creating a globe, the kind that you see in corners of rooms or on desks. I created a sphere and added my texture to it. It looks ok but I want to add that bump to it that you see some globes have. What is the best way of doing this? I added terain to the model adn added it to the as a child so it shares the map but I want the terain to curve around to globe and look natural.
looking for some out of the box thinking.
Thanks,

Displacement channel in the material is a way

Huh, I knew I came to the right place. I am guessing that the displacment map is a grey scale that I paint in Photoshop then?

yupp. And you need Advanced Render for it to look decent (subpixel displacement).

or subdivide the sphere like crazy if you don’t have it (memory/speed hit)

I can’t seem to get it to work. I went into Photoshop and painted in the areas that I wanted raised. I painted onto a seperate file that was the same size and in grey scale. I loaded that into the texture in the Displacement. The little priview that I have for the texture shows the raised areas but when I apply it to the sphere nothing happens, it is still smooth. What am I doing wrong?
Also I do not have advanced render. So should I change my sphere which is now 100mm and 48 segments to like 100 segments, is that how you sub divided?

Huh, I got it to work when I applied the texture to a flat plane. But it when it is on a sphere I can’t get it to work. Is there something that you need to do to add this to a sphere?

displacement only works with poly objects so you have to make the sphere editable.
more segments is subdividing, yes. You can also put the sphere in a HyperNurb so extra subdivision happens at render time. You can subdivide before render, at render time or a combo….

That was it!!! Thank you. As soon as I made it editable and rendered it it showed up.
Thanks much!
