Hi,

I'm a learning user.

I'm about 2 months in and I have need to create/edit 16bit HDR images, for conversion as a color map for a video game (kerbal space program, I'm making a 16K HDR "skybox") to DXT BC6 or BC7.

 

In my reading I keep seeing that: "PDN and TIFF cant do that in Paint.net", but I doubt that because I'm jumping into another free editor, Kirita, (but paint.net is a way better program...other than no exr??) and it can do it.

 

Where is the plugin (or option inside default program if I'm missing it??) that would allow be to do as I wish?

 

I'm not picky on format as long as I can save final image to a 16383x16383 pixel MAX image size WebP or Tiff file... so Compressinator or other advanced DXT compression tool can work with it?

 

Sorry if this seems a noobie question for a simple image format, OpenEXR is 100% open source and its "the HDR editing format" (so I read)

 

Thanks a ton

I assume you're talking about 16 bits per channel.  Paint.NET only supports 8 bits per color channel; for a total of 32 bits per pixel.

Krita is way more capable than Paint.NET.  However, Paint.NET has the advantage of being much easier to use.

whats the "best" free raster image editor in the FOSS, free, open source worlds?

 

I have GIMP, Kirita & Paint.net..... I find Paint with plugin packs more powerful than gimp (but i'm a noob)

 

I'm just mastering tiff editing under 16K and, mipmaps & DXT / Block compression encoding, NOW I WANT HDR lol

 

best suggestions for working with 16K HFR images for Windows?? thats free lol

On Krita, you do have the option to use plenty of filters that are very similar to plugins for Paint.NET by using G'MIC-QT. If you could name a couple, I could find you similar filters over there, and some has the same names such as Nebulous. A good filters of mine are already based on PDN plugins.

Hi, I'm JEFF...aka "aazard", A pleasure to "chat" with you on this matter (Its hard to get "mid skill level" help)

 

I got stuck (by choice) needing to learn "Raster Image editing", odd "not for the average user" image formats and "color types" (who knew?),  "markdown language" (**where** _we_ #write ##like ###this, and make lines like *** that or boxes like |---|... its NUTS) then this "VisualStudio2019" (I know nothing and I can make working "DLL's", its seriously WRONG!)

 

I fix desktops, laptops and mobile phones for work.. so "cowboy learning" is like my thing... I'm not "slow" and for my area of work, I'm considered friendly and sociable (aka "neurotypical"). But this is almost getting "out of hand" lol

 

I make textures and normal/etc maps for "Unity games" namely "Kerbal Space Program" for which I make/maintain the mod "HumanStuff"

I was using Paint.net a ton, but NOW I'm into using EXR & other HRD images as masters (the max support in this unity version, for pixel size, is 16383x16383 as it cant do 16384x16384, so "THE golden" size we see as ideal is 16380x16380, its fully divisible by 4 (so no padding), and it resized "down" well to "true resolutions" like 10240x10240, 8096x8096, 6144x6144 and 4096x4096 (the most common "package" sizes used in texture mods for the game).

 

I'm after: Sorry to seem needy. I'm just "getting ok" with this digital art stuff lol

 

DDS: A8 & L8 formats, plus DXT1, DXT1a, DXT5-BC3, DXT5-BC3n BC6h & BC7, RGB 16/24/48 bit, RGBA32 & RGBA-Half. < I use Compressinator & Nvidia tool to encode so its mostly for detailed pixel "size" & mipmap level viewing

 

Why DDS encoded images? RAM use basically, if your not aware. Graphics cards are freed from "on the fly" compression of other formats to dds (with makes things far more efficent, at best ratios of file/image, size:quality:computer resource usage

 

EXR: This is the format typical used for LARGE HDR images (like the "sky")

 

TIFF: AS ADVANCED AS POSSIBLE

 

WebP: My "distribution" format to secondary editors, MUST FULLY SUPPORT ALPHA, TRANSPARENCY, TRANSLUCENCY & ANIMATION

 

GIF/APGN/JPG/BNG/HEIC/HEIF/AV1/JXR/JPEG2000 are used seldom (only in "special cases" as a "distribution" format), BUT when used the idea is normally as "optimally" compressed with minimal quality loss (like I even have to mention that). So plugins that "tweak out compression options" are GREAT

 

PDN (paint.net) PDS (photoshop), and then if possible something that allows similar function to xNormal and/or Normal-Maps-Online 

 

Blender files? nodes? Producural texture generation? <<--- dreams (my skill level isnt there yet)

 

BATCH FILE OPERATIONS!: namely bulk (5000 images) mass resize, format conversion, "vertical mirroring". <<-- this must be as reliable as possible

 

I'm currently stitching together about 3 raster image editors, 3 viewers (a "github"made tool, Irfanview64, XnView Classic), and mostly use XnConvert & Caesium Image Compressor for "advanced" stuff. BUT XnConvert is not so great after 100 200mb images load up (it sometime causes BAD alpha artifacts or odd "semi-clamp/mirror" doubling <- you'd have to see it, words cant explain in english

@aazard you can find some of your requested filetypes here https://forums.getpaint.net/forum/46-filetype-plugins/

 

DDS is built in. WebP is available as a plugin as are some of the others. TIFF support in also built in to PDN, but is basic.
