Place holder textures are a crap load of time? I somewhat misunderstood, I guess, I thought you had some custom models ready for use. And if you place making Multiblocks above assigning the most basic texture out there to some things for some screen shots, I guess there's a reason why I've heard a lot about the mod but only know the name, the concept, the mechanics assuming they haven't been reworked to death and back again(ie if the mechanics are vastly different then what it said in the old thread), and the team.
As a reminder, Placeholder Textures aren't even any time beyond assigning a texture you have(aka that 4 squares, 2 black 2 pink texture for missing item icons), so I'm curious what you're even doing.
Again, want hype? Let it generate naturally. Don't hype it yourself beyond the basic concept of making hype.
Azanor has this down pat. His youtube sneak peaks are all perfect because it's all show, and no tell. This is what it looks like, this is a glimpse of what I do with it, but I say nothing before it's released and let the world build the hype it wants itself.
