Hello all - I have been trying to import a tiled grayscale map into the editor. Each time I try, it tells me that the files I’m trying to import are color .png. With the very first attempt, this was true. However, I corrected the files in photoshop, removing any and all color information. Still, UE4 thinks they are color, and won’t import them. Any help and advice would be immensely appreciated
The original terrain was created in GeoControl 2. The .bmp height map was sliced up and saved as a tiled world, in Photoshop CC. Saved as a 16 bit grayscale .png file.
Did you also change the image mode from RGB to “Grayscale” (its noted in the image title bar).
You can remove all the color as you want, if its still an RGB image, it will import as color.
You are correct when you think you need 16 bit grayscale images.
Yes, I changed the mode to grayscale, made sure it was 16 bit, selected the red channel to be the final map, got rid of the other channels, etc. I did all that I could, as far as I can tell, to make sure the file exported as grayscale. But each attempt at importing delivered the same message: that it was a color image where grayscale is expected, blah, blah, bl
There is no “red channel” in a 16-bit grayscale image.
It sound like you are creating a 48-bit RGB image (16-bits of red, 16-bits of green, 16-bit of blue).
A 16-bit grayscale image has only one channel of 16-bits.
If you are having issues getting it done in PhotoShop, just download the free Standard edition of TerreSculptor, it will read 48-bit RGB and 64-bit RGBA PNG files and save out to 16-bit Grayscale PNG.
