Here is what I have for the Tower so far. Looks better in game.

Hey, looking pretty good. Maybe a little too heavy of a bump map for areas that are not Tarnmatte covered. You could make two separate bump maps, one with the tarnmatte(really heavy) and one without(lighter) and then combine the two to get the desired affect. Just a suggestion.

The heavy bumps on the Tarnmatte and the rust on ladder remain. I smoothed all other bumps on the tower a lot.

I packaged up all the latest changes along with the Paint.Net Type-7C Templates I made for the Conning Tower, Deck, Body and Structure. Using the templates you can hide or change any effect or even go for the just got painted look.

I just updated the download a few minutes ago.

The upper part of tower looks like is covered with a carpet now, that's more like a textile texture than anything else. Personally I liked more the first attempts with much rust and stuff, I stick with that

Rust is not so efficient at absorbing radar radiation.

It looks good. Can use even more displacement as seen here:



Nice work!

You know the term "Iron Oxide" listed in the Tarnmatte materials list...
Quote:
Tarnmatte
This was a radar absorbing material used to coat snorkel heads to shield them from allied radar. It consisted of a compound of synthetic rubber and iron oxide and was claimed to have 90 percent effectiveness in reducing radar signature.
Well guess what that material is... Tarnmatte was made from rust suspended in a rubber compound... Alberich and Tarnmatte are very simular in that Alberich coating contained Air pockets to dampen sound, Tarnmatte had Rust pockets to dampen or reflect the radar return away from the source Radar. Most likely reflecting the radar return signal straight up.
Quote:
Wikipedia: Oxide
An oxide is a chemical compound containing at least one oxygen atom as well as at least one other element. Most of the Earth's crust consists of oxides. Oxides result when elements are oxidized by oxygen in air. Combustion of hydrocarbons affords the two principal oxides of carbon, carbon monoxide and carbon dioxide. Even materials that are considered to be pure elements often contain a coating of oxides. For example, aluminium foil has a thin skin of Al2O3 that protects the foil from further corrosion.

Oxides, such as iron(III) oxide or rust, which consists of hydrated iron(III) oxides Fe2O3·nH2O and iron(III) oxide-hydroxide (FeO(OH), Fe(OH)3), form when oxygen combines with other elements.
I suspect that if the Tarnmatte creation process included some type of controlled polorazation (magnetic alignment). Having each subsequent layer polorized to different angles. The Tarnmatte efectiveness would have been increased even more then the 90% signature reduction it was claimed to have.

As for giving more depth perception to the the Tarnmatte Texture: The game has limits to what can be done. If I try to raise the texture more it will just turn black.

Rust is hydrated ferric oxide. You quoted it yourself from wikipedia. It doesn't say they used rust

Iron Oxides

Iron Oxides
They used a refined form of rust. Iron Oxide is Rust. Rust is the simple term used to describe Iron Oxides or describe the process of iron returning to its natural state.

There is no such thing as a refined form of rust. The term rust is colloquial.

The forumla of rust is Fe2O3.nH2O. When the H2O is bored and leaves for a better place, the thing that remains is Fe2O3 - red iron oxide, the thing you refer as rust.

I'm curious too about the manufacturing process of tarnmatte. I didn't find a lot on the subject.

Refined Iron Oxide would be the process of taking the chunks of rust and breaking it down to a fine powder and removing any impurities so it can be applied to something (in this case Tarnmatte) in a evenly distributed layer and helping to prevent large amounts of any further oxidation.

I also, did not find much if any information on the manufacturing process. I suspect that since it is primarily used in military applications, this information was squelched.

Oxidation

Oxidation of different types of metal can be used for amazing applications.
i.e. Take your typical soda-pop can. The protective surface use to seal the metal surface is oxidation. A acid is applied to the surface disolving the oxidation and depositing a condensed version of that oxidation to the metals surface creating a protective layer(Anodizing). (Alodine)
