I have been using the toolset to try to locate the mmh and mao files for the Blood Dragon Armor. I want to try my hand at retexturing it. I was having problems months ago with installing the toolset. I tried it again yesterday and voila! it installed perfectly fine. I have followed the steps in the toolset tutorial and I have read many posts by Adinos. I have tried usin the DATool to find the textures to no avail. I guess I just don't know what I am looking for. Anyone care to help a newb out?

Blood dragon armour is a DLC so the files is in the addin folder. but i think those .erf files are protected so you simply can't open them. atleast my attempt to open them with the toolset failed.

Yeah, I tried opening those files from the addins folder. I had the same result as you. Anyone out there know how to get those files to open?

The DLC ERFs are encrypted to prevent extraction, but presumably someone must have cracked that, given that there are a number of Blood Dragon texture mods floating around. You don't really need to bother with all that though, as the Blood Dragon armour is just a very poor retexture of Dwarf heavy armour, so you can just use the texture of the vanilla version (pn_arm_dwpa_0d) as a basis. The helmet uses a vanilla model, so use pn_hlf_t01a_0d as a guide. If you really want the dragon logo, download one of the mods to use as a basis.

The filenames are pn_arm_bdaa_0d/i/n/s and pn_hlf_bdaa_0d/i/n/s (the "i" textures are the emissive maps).

EDIT: Actually I tell a lie. While the BDA does use the same mesh, it looks like they changed the UV map. Looking at some downloaded textures, it seems they squished three maps (body, gloves, boots) into one map. My advice would be to download one of the existing BDA texture mods from DA Nexus or the like and use them as a guide.

Cool. Thanks for the reply Darth. Yeah, I was looking at one of the modded Blood Dragon Armor textures, but I really wanted to start from scratch on mine. I may just make a completely custom Blood Dragon armor texture from the ground up  using the Dwarven Heavy Armor texture to start with.

Maybe contact one of the authors of those mods and ask them how they extracted the ERFs.

[Chronogryphon]

That's actually a good idea. I don't know why I didn't think of that. lol

The individual file data of the DLC ERFs appear to be Blowfish encrypted in 64-bit ECB blocks. Possibly those other modders hooked the executable memory space to track down the key that is used in RAM to do the decryption. You can actually find the "BlowfishDecrypt" function name in a strings dump of the running executable, so it's not much of a stretch from there to trace it down. (For that matter, the ERF 2.2 header has two DWORDs followed by a128-bit binary sequence not present in other ERF headers, which very well may be the key itself in some obfuscated form).

Also, either an early version of the toolset had the key built-in (or auto-generated the key by hashing an easy-to-guess password), or else several of the DLC ERFs were distributed w/o encryption or w/ weaker encryption at some point. So a lot of the content you can find out there, such as the Warden's Keep DLC assets floating around, appear to have come from that time frame, but have no recent versions.
