I'm currently in the midst of wrapping up a custom race/faction, but one problem remaining that I haven't been able to figure out. I'm trying to block a research path for this custom faction, the mounted warfare line to be exact. I've edited the faction.xml and indicated to use a customized version of the techtree.xml for the faction like so...
<NonBuildableEnvironmentType>GrasslandEnvironment</NonBuildableEnvironmentType>
<TechTree>TechTree_Tzeentch</TechTree>
<Spellbook>DeathSpellbook</Spellbook>
<FactionType>Major</FactionType>
<RemCustomizationPts>0</RemCustomizationPts>
I've commented out the associated techs, in the techtree.xml...
<Category>Warfare</Category>
<!--<Tech>Advanced_Archery</Tech>-->
<!--<Tech>Archery</Tech>-->
<Tech>Armor</Tech>
<Tech>Blacksmithing</Tech>
<Tech>Drills</Tech>
But no dice. I don't see why this doesn't work. Any suggestions?
