fixed Liveries seem to be missing mipmaping

[Quetzalkoatl]

I noticed that some files in default liveries are missing mipmapping which causes small spots and thin lines to flicker during view movement.

You can see in this photo that nose section has those small white dots (and those are flickering), rear section doesn't have this issue as it has mipmaping. (Probably a video would show it better - for seeing the details please open this screenshot to the full size, dots I'm talking about aren't visible without it)

Here are all livery folders with files that I suspect to be missing mipmaping (marked with see-through red) - they seem to have higher size than files with mipmaping.

The fix is very simple, all that needs to be done is resave files - just now with mipmaping.

Hi. I cannot replicate the white dots with current OpenBeta.

Hey, that's not how mipmaping works.
You won't see the difference when viewing from close up.

Mipmaping makes livery to have several "layers", each one has 2 times smaller linear dimensions than previous one - and they are being swapped by DCS when viewing same livery from various distances.

When livery file is missing a mipmaping then from farther distance it appears that some parts of it (usually details like lines, digit edges, small points) start flickering during camera movement.

When watching your track file I can still see it very well.

It's also possible to view it in model viewer.

The fix is very simple, I can do it myself with use of free paint.NET... all it needs to be done is to resave files that have the size of 16 385 KB with setting BC1 (linear, DXT1) + generate mipmaps. After that livery no longer has those issues and its size matches other files (10 923 KB) that appear to be made correct way.

It most likely will look different on professional software that devs are using.

I understand what needs to be done according to you.

However, I can't bother devs with a problem that I'm unable to reproduce. Are you sure the issue is not on your side? Are you using an AMD GPU, ReShade or another external software which purpose is to alter graphics?

[Quetzalkoatl]

I'm sure it's not on my side. I am using GTX 1070, no any mods that would alter in-game graphics.

I made a comparison video that shows the difference between liveries with and without mipmaping, I hope it would make it more clear what I am trying to point out.

Thank you for the video. Now, I see what you meant.

It seems that KA-50_3 liveries are being fixed internally, but I'm not sure they'll be ready for the next OB patch. Cross your fingers.

@Quetzalkoatl Is it fixed for you, now?

[Quetzalkoatl]

Yes, it got fixed in 2.9.1.48335.

Thanks for your feedback.
