importing planet height and color textures

Thejazzshadow · October 16, 2009, 04:47:54 PM

I have run into a dead end. I have some planet height and color textures and I can't figure out how to get them on the planet. When I use image shader, it doesn't cover the whole planet and it moves with the camera.

Image shader is the right start, make sure the projection type is set to spherical and the image center is the same as the planets center (usually 0, -6.378e+006, 0).
Hope this helps

Thanks. I got the color to work great but I can't get the height one to work. I have a photo that shows the earth's heightmap but I can't get it to work.

Have you tried giving the heightmap some extreme values. When I've used these in other 3D apps, they don't show up well without high values. If you think of the size of the Earth, and the height of Everest, Everest is not all that large.

I'll try that... While we are on the topic of image files, when I add a a texture to a rock population, how do I find the center coordinates?

I do not know, sorry. I use procedurals to texture nearly everything.

İ am new to TG2 too ,but i think if you right click on the 3d view anywhere you want ,you can copy the coordinates and then paste it. İf this it what you are after.

Edit : Maybe you saw it here. This tutorials helped me a lot http://forums.planetside.co.uk/index.php?topic=6505.0 But here are other very good tutorials too.

You should use the height data (assuming it's in a spherical projection) loaded into an Image Map Shader with the same settings as your texture shader, and with Displacement Enabled. For realistic height I guess you'd set it to the height of Everest, tallest mountain in the world.

But you will probably find that to not be very noticeable, so you might need to exaggerate it. Remember, it's measured in meters.
