Hi, two questions.

-I'm trying to modify my beaker choice in game using the overrides but I keep getting the defaults. Any idea what I'm doing wrong? Can't even get one to work by itself. Typed in this:
logistic-science-pack=triangle/liquid_green

And tried a bunch of other combos too. Thoughts I had:

a. A conflicting mod. I don't think this is the case though because Colour Blind Science Packs, when I change nothing else and enable that, works fine.
b. I'm using a dash or underscore wrong somewhere, but it looks fine to me.
c. Maybe I simply don't understand the overrides and what I'm trying to do doesn't work this way.

-The information page mentions a gallery somewhere but am either really blind (possible) or the link is missing. Where can I find that?

This mod is only an graphics pack and does nothing on its own. Combine it with a mod like Colour Blind Friendly Science Packs to actually change the science flasks in the game. From my own testing enabling Colour Blind Friendly Science Packs and setting the Flask overrides to logistic-science-pack=triangle/liquid_green works as expected.

For diagnosing problems with overriding the selected shape look into your factorio-current.log file for any lines starting with a number followed by Script @__quality_glassware__. With no Flask overrides set it should say something like this:

   1.317 Script @__quality_glassware__/data.lua:196: Quality Glassware assigned automation-science-pack=cone_normal/liquid_red
   1.317 Script @__quality_glassware__/data.lua:196: Quality Glassware assigned logistic-science-pack=cube/liquid_green
   1.317 Script @__quality_glassware__/data.lua:196: Quality Glassware assigned military-science-pack=sphere_spiked/liquid_black

   1.317 Script @__quality_glassware__/data.lua:196: Quality Glassware assigned cryogenic-science-pack=cone_normal/frozen_blue
   1.317 Script @__quality_glassware__/data.lua:196: Quality Glassware assigned promethium-science-pack=klein/liquid_blue

If it doesn't the Flask overrides setting will not do anything. Hope that helps.

Oops. I forgot to add the gallery, I'll get to adding that later.

Thanks!
