====== Greyscale PNG image ======

You can import terrain elevations to Visitor 3 by using grey scale PNG image.

Use a 16-bit PNG at 4096x4096 for a 4096x4096 terrain grid size (Make sure the PNG is a power of 2 ie... 128, 256, 512, 1024, 2048, 4096...). The image started of in Photoshop as a grey-scale 8-bit PNG, then imported into [[:tools:wilbur|Wilbur]] (as Surface PNG file) and saved as 16-bit in P:\ drive. Then make the .pbl file in the P:\ drive in same folder as PNG:

Check the Terrain.pbl file:

<code cpp>
class cfg
{
	PNGfilename = "Terrain.png";  <-- Make sure this is same name as png file
	squareSize = 10; <-- Make sure same size as "Terrain cell size" in Visitor
	originX = 0;
	originY = 0;
	minHeight = 0; <-- Adjust as needs
	maxHeight = 400; <-- Adjust as needs
};
</code>
Then import into Visitor.
