Crafting question; what all affects item level?

[Hanuman]

When crafting furniture/art/weapons, what increases the chance of crafting a higher quality item? Is it really affected by lightning and cleanliness of the work room (and even beauty rating)? The mood of the crafter etc or just the crafting rating and some RNG thrown together?

is it hard to make masterwork level stuff when making weapons?

thanks

Craft skill, manipulation (and possibly consciousness, too), the light level. I think those are the big three. I don't know about mood or cleanliness.

And yeah, it's really hard to get masterwork-level stuff. I've got a skill 20 crafter pumping out pants and shirts and she averages about 1 masterwork per 10 she makes. I think it's a random chance. Like, at skill level 20, with everything stacked in your favor, you've got about a 10% chance to make a Normal, a 30% chance to make good, a 50% chance to make excellent, and about a 10% chance to make masterwork.

Also, if you have a production specialist (from a meme that supports said role like "Human primacy") that pawn gets a "+1 quality to crafting or construction" bonus.

Using a heavily modified/upgraded pawn that is also the production specialist, it feels like i get masterworks very often (and pretty much always legendary items if i have inspiration).

Most of the details can be found here. https://rimworldwiki.com/wiki/Quality

It's nicely set out I think.

Oh cool, does it really top out at lvl 20 or can the specialist in essence be a lvl 21 crafter?, having higher chance of masterwork+ than normal lvl 20?

The skill tops out at 20, along with the percentage chances for creating any given item quality. Production Specialist simply auto-upgrades that random item quality by 1 level - so if you roll the 0.01% chance for Poor quality, it becomes Normal instead; if you roll the 9.51%) chance for Masterwork quality, it becomes Legendary instead (normally you can only make Legendary items when you have a Creativity Inspiration).

This means that getting a Creativity Inspiration on a Production Specialist at or around level 20 Crafting gives you nearly a 95% chance for a Legendary item. This combo gives a better than 50% chance for a Legendary item just from having level 10 Crafting (or Construction for certain furniture pieces).
