View Full Version : SOS Procedural Terrain with Custom Altitude Map Please Help

12 December 2010, 04:08 PM
Hi,I'm trying to create a procedural Terrain with a Custom Altitude from a Map but I try to blend the simple fractal with my altitude map (via Texture Map) in the function editor.

I connect the fractal with the blend using rough areas (also try altitude)and to the texture using grayscale output (doesn't give me too many options)

but the final output is really bad please someone point me in the right direction. :banghead:

Make sure you have interpolation turned on for your map. It looks like it isn't.

Hope that's it :-)

Best regards

My one minute solution, You could edit the terrain object and then retopoligize it. It will change it to a standard terrain but it will look better. I'm assuming you want to make a sand dune...if so, there are material presets to make it look better from there. If you still have issues, put your scene into a zip file and upload it if you want to make it easier for people to help/give input.

Connect the 'simple fractal' and the 'blender' nodes by 'altitude', 'rough areas' won't work for what you want to do.

As MikeFrampton said, make sure you have interpolation turned on for your texture.

Also if you are using a standard procedural terrain and not an infinite one, make sure to uncheck the 'zero edges' button in the terrain editor.

ALso check that image you using at list 1024x1024 or higher resolution and not compressed.
