[texture.load.png.error]: ***** A PNG loading error occurred for /Users/ericwalch/Library/Application Support/Oolite/AddOns/ZygoRoids v1.oxp/Textures/ASTbDIFFUSE.png: bad adaptive filter value.
This is because a library to handle PNG files on the mac is updated (No problem on 1.76 or on windows/Linux).
The cause is that the PNG is saved in 'interlaced' format. Currently those textures are pitch-black on the mac
I have not tested if this problem is still present in your latest release. And even when this is a bug in the mac version of Oolite (Bug #18622), there is no reason to use interlaced coding in Oolite textures.
