Subject: Biome dust node: Only place on 'walkable' cubic non-liquid drawtypes
X-Git-Tag: 0.4.17~53
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=a90c314c80b87abbaa7668a55bc0d1194dd0920f;p=oweals%2Fminetest.git

Biome dust node: Only place on 'walkable' cubic non-liquid drawtypes

No longer decide placement on 'buildable_to' parameter.
Dust nodes only look acceptable placed on cubic nodes.
Modders may not want to make their plantlike decorations 'buildable_to'.
