Maximum size for .dds texture (4096px ?)

[Mav783]

Hi,

 

In DCS, textures's files are max in 4096px in .DDS.

I want simply to know if DCS World can support files more than this size (in .dds format) ?

 

Thanks for your answer ;)

The only problem is when creating as psd in Photoshop. The storage process of the textures takes longer.

As long as you're still working on the skin, and use it for testing, you can save it as uncompressed.

It's way faster to save, but takes much more disk space.

 

4K, Color only, BC7 8bpp, Fine, no mip map : 16Mb, Saves in 3-5 sec.

With mip map : 21.3Mb, Saves in 4-7 sec.

 

4K, Color only, uncompressed, no mip map : 64Mb, Saves in <1 sec.

With mip map : 85.3Mb, Saves in 2 sec.

 

8K, Color only, BC7 8bpp, Fine, no mip map : 64Mb, Saves in 10-12 sec.

With mip map : 85.3Mb, Saves in 12-15 sec.

 

8K, Color only, uncompressed, no mip map : 256Mb, Saves in 1 sec.

With mip map : 341Mb, Saves in 3-5 sec.

 

For reference only (don't do this) :

16K, uncompressed, no mip map : 1Gb, Saves in 5 sec.

16K, uncompressed, with mip map : 1.3Gb, saves in 15 sec.

16K, BC7 fine, With mip map : 341Mb, Saves in 85 sec.

 

So, if you want to do a quick save to test in the model viewer(/in game), use uncompressed and disable mipmap generation. For the final version, compress using BC7.

 

Keep in mind saves times will vary according to your computer performances. With my former laptop, a 8K save with BC7 used to take 5 minutes. If I don't consider the safety shutdown to prevent overheat.

Ok thanks for your answer Urbi.

 

Yep, some planes uses 4096px textures, but multiples "4096px files" can be used for one full part of the plane.

I hesitated to do that but it's not possible...Doing this mean to access the 3D models and remake the UVW map...And it's not possible.

 

So i think i will simply use the original one and upsize it in 8196x8196px, even if it's heavy.

I know it is possible with a .psd file...But i didn't know DCS can support such resolution in .dds. So ok.

 

And thanks Clorydric for ur advices ;) That will help me !

When I make my liveries I normally save in PNG for testing in the ModelViewer then save as dds for in game.

[Mav783]

Ho cool ! Didn't know that .png can work with ModelViewer. Thanks :thumbup:

Hey guys, i have an other question.

Do i need to indicate in the "description.lua" file the definition of the .DDS connected to ?

 

Thanks :)

Small side question. What tools do you use to manipulate or create dds textures?

[Clorydric]

You can use :

- photoshop (paid, a bunch of $$$ per month) with the Intel DDS plugin ( https://software.intel.com/en-us/articles/intel-texture-works-plugin )

- Gimp (free) with gimp-dds plugin ( http://code.google.com/archive/p/gimp-dds/ )

- Affinity photo (paid, one-time fee of ~50$ iirc) or any good picture editor, but you'll need to import/export in TIFF, and convert to/from dds with an external program.

Guys...I'm so sorry, i have an other problem/question :

 

I donwloaded the .PSD file of the Mirage 2000C here :

https://forums.eagle.ru/showthread.php?t=158552

 

And theire is a difference beetwin the .PSD vesrion (and i need a .PSD files cause layers !) and the original one in game.

 

The PSD one have "albedo" texture where the original one have "sratched" textures.

And the blue color is not the same.

 

.PSD here :

 

And the original one here :

 

You know if i can find a .PSD version that is closer to the original one ?

Thanks ;)
