Material affected by waste ?

Hello there !

I was wondering how I can "see" that an item is affected by waste (more precisely, by blueprint material level) ? Because as far as I can see, everything is affected by waste, except the tech 1 version of an item and the R.A.M. (in case of T2 items manufacturing)

I might be wrong, but I didn't find that information anywhere on the forum / wiki / google.. But i'm sure this question has already been asked ^^

Hope you can give me a hint !

Regards,
Althalus.

It can be pretty confusing when you hit T2 stuff. Quick overview:

1. Materials for building something may be on invtypematerials and/or ramtyperequirements
2. Materials on invtypematerials are subject to ME
3. Materials on ramtyperequirements are not
4. For T2, take note of ramtyperequirements.recycle. Where this is true, you need to reprocess the material and subtract the reprocessing amounts of the materials from the thing you want to build.

Here are some links:
See CCP Explorer's posts in this thread

And this page took me a few attempts to digest but has some good stuff on it:

I already had both links, but in the first, CPP Exporer use an old table for his query (i've read it's a view from invTypeMaterials and ramTypeRequirements, or something like that) so it was a bit confusing... and the second didn't says anything about waste (well it does, but it's not so much clear...) ^^'

But well, it's just good now :)
Thanks for informations !

There are three types of waste, when you produce items: material, skill and production waste:

Material waste occures when you build from a non-perfectly researched blueprint and affects only materials which are from the invTypeMaterials table.

Skill waste happens if you don't have the Production Efficiency skill at level V.

Production waste is when you manufacture at production lines that have material multiplier, like Advanced Ship Arrays or the Rapid Equipment Assembly Array.

Both skill and production waste are applied to raw materials (invTypeMaterials) AND to extra materials (ramTypeRequirements) that are in both (!) tables (see also http://www.eveonline.com/ingameboard.asp?a=topic&threadID=1561558)

You can find all production formulas on http://wiki.eve-id.net/Equations

I like to use http://eve-online.itemdrop.net/eve_db/items/Blueprint/ as it clearly shows extra materials.

Note that these are all database values, so there is no waste included on materials that are subject to waste.

Example: Shrapnel Bomb
