Yet another one: effects/gradients/gradsteamthin.dds turns white steam into black steam. Not sure I trust gradsteamthick either but not sure where to find that one in game.

I'm confirming this from the Wet & Cold install... black breath. Restoring the files restores the breath to white.

I've had this same problem pop up before, only it seemed to turn All shadows white and light Black on the ground. Like the two shades traded places, That was bizarre.

Found another problem texture from Skyrim - Textures.bsa. textures/effects/gradients/gradsmokediss.dds

 

Optimizing this texture results in the steam coming off waterfalls to get blocky/pixelated briefly every 2-3 seconds.

Using the preview viewer in DDSopt, the alpha channel looks the same in the vanilla and optimized texture but the primary channel doesn't. The DDSopt logs for that texture has a note that says "Automatic greyscale conversion.".

[Besidilo]

I somebody maintaining an exclusion list that includes the textures mentioned in the DDSopt guide and here on the forum? I've had troubles getting the optimised textures to work properly in the last couple of days.

I put them on my guide as they are found and remove once INI is updated by ETH. Obvious a day or so delay of course since I work.

Yep, I see that. It looks like the alpha channel was converted to a two-tone mask and applied to the empty primary channel?

The correct INI entry to fix this issue is:

[AlphaCustom]
; Black smoke ??
effects\gradients\gradsmokediss.dds

Confirmed that this fixes the issue. Texture remains modified, but primary chanel remains identical. Adding this entry inder [AlphaOpacity] had no effect.

[Kelmych]

I didn't suggest an INI change for the horn candle since it might affect DDSopt processing of the (better) Tobes version of this candle which DDSopt handles properly. I thought that the Riverwood Trader sign was mentioned before.

[z929669]

Yes, there are a couple of other ones that need to be added to the ini ... most likely under [AlphaCustom], but not sure.

[Kelmych]

I looked at the primary and alpha channel views in DDSopt for the set of 11 textures: textures/effects/gradients/gradsteamthin*.dds and textures/effects/gradients/gradsteamthick*.dds .

It looks like they all have the same problem as with gradsmokediss.dds. The alpha channels look the same before and after DDSopt processing but the primary channel is corrupted. I assume this set of 11 textures should be added to the same INI change, but we'll need to check and see if this works properly of course.

The initial version of the updated Mod Optimization portion of the DDSopt guide is now available. The purpose is to allow users to decide which STEP mods to process with DDSopt. This version has, for each STEP mod that contains textures:

- indicators on whether DDSopt provided noticeable improvements in the textures

- the maximum resolution of the textures in the mod.

 

More details are in the introductory portion.

This information could be and would be best placed on the DDSopt Guide as a tab. Of course, disregard if you're planning on doing that after getting it more updated.

Yep ... I assume that these could be dissipation maps, as they are named this way. Did you check all of the color textures of just those named *diss.dds ?

 

Actually, what we can do is add a wiki page for the DDSopt.ini wrapped in

 elements and use that as a log for all of the INI additions that are needed based on our findings. This should be another sub-page of the DDSopt Guide [ wiki.step-project.com/Guide:DDSopt & Texture Overhauls/INI ]

[Kelmych]

I didn't look at all the *diss.dss ones yet. I was looking at the steam ones that Neo and others mentioned seeing with breath turning black vs. white.
