New nodes: Color map and normal map multi file export

Instant Terra v1.6 has two new nodes to export color maps and normal maps as several files to optimize the rendering times for very large color or normal maps in an external engine.


Using the same file pattern formula as the terrain and mask tiled export, the files are exported as tiff, png, tga, or bmp file formats.


The width and height is set in number of vertices and the number of files to create based on the overlapping parameter.
  • If overlapping is set to 0 the file is cut into parts, and the parts have nothing in common.
  • If overlapping is set to 1, two contiguous parts will have a column or a line in common.
  • If overlapping is set to 2, two contiguous parts will have 2 columns or 2 lines in common.


The width, height and overlapping can be driven by calculation nodes linked to the optional connectors. In the example below, the width of the export is controlled by a constant value of 40.
