Generating map from latest stable minetest version (5.2.0) shows unknown nodes in minetestmapper console output

[juozaspo]

Trying to generate a map last loaded in latest minetest stable version results in warning about unknown nodes while generating output image. The invocation and output is as follows (minetest stable is installed in same parent folder as minetestmapper):

Warning: Falling back to using colors.txt from current directory.
Unknown nodes:
	butterflies:butterfly_violet
	fireflies:hidden_firefly
	butterflies:hidden_butterfly_red
	butterflies:hidden_butterfly_violet
	butterflies:hidden_butterfly_white
	butterflies:butterfly_white
	butterflies:butterfly_red
	fireflies:firefly

Perhaps these nodes should be recognized but not rendered, as to not confuse users.

Thanks for making this and for making it open source. Its helping me help my son - good times :)
We hit this error when trying to map the Minetest Clone 2 game.
Perhaps some configuration file mapping x:y where x is unknown/incoming node name and y is the known node name?

This is what we see:

$ minetestmapper -i ~/snap/minetest/current/worlds/mc2/ -o map.png

The colors.txt shipped with minetestmapper is intended for use with Minetest Game, it doesn't work with MineClone.
You'll need a colors.txt generated specifically for use with MineClone.

Here's one generated from MineClone2 0.69.0: colors.txt

Edit: replacement list in case anyone wants to repeat this process with the new script I just pushed:
