Painting FSX planes

[Brett_Henderson]

DXT is compression format, DDS is fileformat. DXT5 is the best quality compression. You can do uncompressed 32bit DDS files if you want.

That makes sense.. I just dug up the textures from my C177RG.

I used DXT3 for those... I opened one with ImageTool, and save it as a DDS..

Then opened THAT with DXTBmp, and saw that it was "DDS DXT3"..

OK then,, understanding that DXT5 is the best compression, and DDS is "only" a file format.. why even bother with DDS ?

 

[bushpilot]

Well beats me, probably DDS offers better frames over BMP. My knowledge on the issue end right there LOL.

Choices are:

32bit BMP

DXT compressed BMP

32bit DDS

DXT compressed DDS

 

[Brett_Henderson]

There's gotta be something more to the DDS step. As noted earlier.. the poster's problem was solved when he used ImageTool, instead of DXTBmp for the DDS conversion (and why I wouldn't do any compression/conversion at an editor via plug-in).

 

[Lionheart]

I could never get DXTBmp.exe to compile my DDS textures right. Then nVidia came out with the famous Photoshop tools that can create DDS and bump maps.

If you do not have Photoshop, then the newest version of FSX ImageTool can do what you need, and it has autoflip in it when compiling to DDS format.

On formats; You can use only 2 for planes; DXT5 and 888-8. If another works (for planes), I do not know about it. DXT3 doesnt work, (in DDS format).

Regular format.....DDS-DXT5
High Rez.............DDS-888-8 (32bit)

High Rez takes alot of memory, so some are making the files double size (2048 instead of 1024 in pixels, square size), and keeping them in DXT5 format/resolution. Does the same as 888-8 with 1024 size, but DXT5 is 'faster' for the computer.

Thus.....

Regular textures with no details should be 1024 size, DDS-DXT-5 format.

High detail texture sheets.... Double size at DDS-DXT-5 or normal size 1024 with DDS-888-8 32Bit high rez.

With Photoshop, you can assign DDS textures to always be opened by Photoshop, so you can go straight into a model folder in FSX and start opening them directly with Photoshop (if it has the nVidia tools in it). Really awesome. Just flip them over to work on them rightside up, then flip vertically again when done, save as DDS.

Now.... If (if) you have a super computer, and you love massive detail, you can go quad size (4096) and save as DXT-888-8 high rez DDS format, and you will have amazing detail. But no one paints in 4096 (that I know of.. Chris might though. He is really into high details). So if the work isnt in 4096, its not worth it. If it is though, its well worth it. But you need the PSD files (layered originals) to burn the DDS from. Bloating up a 2048 to 4096 will 'not' create new detail, so you're best off keeping it at its present detail level as you will not improve it.

Thanks, I've learned a lot here.

 

[Brett_Henderson]

Thanks, I've learned a lot here.

Me too

But I', still thinking there is more to this DDS thing... Because DXT3 BMPs work fine in FSX.. just like DXT5 BMPs, but a DXT3 coverted to DDS does not work, while a DXT5 converted to DDS does work.

 

[bushpilot]

Just out of interest I googled a bit:

Compared to other image formats:

"DDS textures are sent straight to the video memory, stored as is (compressed), and uncompressed on the fly by the hardware at no cost (in fact, there is a gain because there is less memory access)"

So the difference should be in performance.... who knows.

Me too, But I still thinking there is more to this DDS thing... Because DXT3 BMPs work fine in FSX.. just like DXT5 BMPs, but a DXT3 coverted to DDS does not work, while a DXT5 converted to DDS does work.

. . .and what part, if any, does DDS play in bump mapping? Thus far, the only thing I've learned is that some folks swear by this Imagetool thing but DXTbmp seems to do the same thing, so why do some parts in DXTbmp then switch to Imagetool to complete if DXTbmp can do everything anyway? Also, aside from the stupid "flip" that's required for FSX textures (can someone explain the genius in that?) I see nothing different between FSX and FS9 repainting. The bump mapping is apparently the big difference and why isn't that possible in FS9?

 

[Brett_Henderson]

FSX painting is a bizzare witch's brew .. LOL..

With FS9, it was just an image with an alpha channel. FSX is that, and a specular image that has its own alpha, and then the bump-map. The image, spec, and their alphas amount to FOUR variables; as well as a dozen or so settings and sliders.. as you're trying to get things like reflection, shine, chrome and varying transparencies.

Mapping all of this stuff is time consuming. Take a look at the FSX SDK.. and then apply that info while in Gmax.. it's mind-bending.. (too a simpleton like me)

As for swearing by ImageTool.. I've had countless problems using DXTBmp for the DDS save. Not sure why, it just isn'r dependable.

The image flipping (as explained to me), saves a step on the software side of it. Images as mapped in Gmax need to be flipped by FSX before rendering them. It has always been that way. Pre-flipped DDS images take that step out of it.. considering how many images are rendered for 3D display.. it makes sense that that would add FPS.

ANYway.. the whole texturing thing is so complex.. I need a very strict set of step-by-step... else I make a mess of things and can never sort out why my spinners are black, and my glass is invisible.. LOL.

1) All editing done in PSP.. 2) DxtBmp is used only as a place for adding the alphas.. flipping everything if required (i.e. editing an existing texture).. and is a reliable DXT5 compressor. 3) Convert the DXT5 to DDS with ImageTool.

 

[bushpilot]

ImageTool is very handy. I usually use it only to batch converts or creating bumpmaps.

 

[PRB]

Lots of good stuff here. Thanks to all for the help. Here’s the WIP. Executive Airlines was an outfit that operated in the Northeast many years ago, in the 1960s and 1970s. Maybe as late as the early 1980s. The very first Twin Otter I ever saw was one of these, flying in and out of Augusta, Maine (KAUG) on a daily basis. My brother and I would hide out by the end of the runway waiting for one to come in. It was the biggest thing to operate out of KAUG, after all!
<?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o></o>
The nose is going to be a bit of a challenge. And I still haven’t found where Aerosoft hid the darned propeller spinners. I need to paint them blue! And some other odd things. There are various air scoops that pop out of the blue paint, but are not painted. From looking at the layers in Photo Shop, they should, at the least, be covered with blue paint. Not sure what’s going on there…

FSX painting is a bizzare witch's brew .. LOL.......

Exactly why I'll never get into it. MSFS took a relatively simple process and made it unwieldy and overly complex. I admit that the bump mapping is interesting for the 10 seconds or so I spend looking at the exterior before I fly and the specular lighting and self shadowing is also interesting but a mere sidelight to the actual flying. I can't say I've ever spent much time admiring the rivets on a native FSX aircraft, or how the shine looks so darned realistic or how that cool shadow in the VC moves with the light. I guess it's personal preference obviously and progress is progress, so all this is necessary but for those who don't understand it, or don't care to learn the complicated task of repainting FSX aircraft and always enjoyed repainting before this, it's just another good reason for sticking with our favorite portovers and DXTbmp.

 

[bushpilot]

I'm for progress and stuff, although I usually just paint diffuse maps and let speculars and bumps alone.

But FSX is just so much more superior when it comes to eye candy:

Shots of the upcoming McPhat Studios Super80 UHDT paintpack, I think it's sort of a showcase of FSX capabilities

 

[Brett_Henderson]

WoW !! That's beautiful ! It might just be eye-candy, but it's all those little things that help fool our eyes and enhance the realism. Shimmering water, and clouds that cast shadows fall under the same catagory as subtle, 3D rivets and seams.. and true, specular shine. Plus there's the artwork aspect. The above shots show off ART.

Repainting for FSX isn't all that more difficult (with a good, layered paintkit).. it's just more time-consuming. It's easy enough to change a livery and just use existing specs and bumps .. although even the livery coloring (stripes logos etc) can be highlighted in the alpha, spec, and spec-alpha.. so you have to take care of that... else your United repaint will look like the paniters got lazy and just painted over it, 'cause old lettering/stripes will show through in a weird way.

Now, when you create a set of FSX textures from scratch, for a new model, it's quite an involved process. I'm still struggling with it.

The Gimp does Alpha pretty good by itself -

Was able to just pull up the default C172 as a test in the Gimp latest Verion, with the DDS Plugin, and it has a pretty good Alpha conversion already loaded. Anyways, for those that be cheap like myself, Gimp is Free, so is Image Tool ->

# Launch Gimp
# Pull up a copy of the C172 Texture that you copied from an Existing Paint, I just grabed a copy of the Plane Jane White.
# Load the C172_T.dds in a Gimp Window
# The Alpha will be loaded, so we have to remove it before we start painting.
# Click on Layer -> Transparency -> Remove Alpha Channel
# Ready to Start your Painting using the Gimpy Tools,There be allot of good stuff so you will need figure what they are, I'm no Expert.
# My favorite tool is the Fuzy Select, Instant Paint Job with my Favorite Color.
# I'm pretty sure you can copy decals and Text onto your bird, as well as flip it and move it around.
# When Done, Add the Alpha Channel back in, Same Steps as above accept Add Alpha Channel.
# Now you can add your strength of alpha into the Layer by Clicking on Layer -> Tranparency -> Color to Alpha
# I made mine all 000000 which is the Darkest BLK.
# Anyways the Fuzy tool is real good for this because you only want to select metal parts for the Alpha, Want to be skipping the Tires and Rubber parts, engines, nacells, etc.
# Save it when your done, Pull it up in Image Tool Save as DXT5, Done !!

# Just an FYI on the Gimp -

Hi
I use a batch file to convert 32bit bmp masters to dds
Basically I build the texture the same as I did for fs9,when finished I run this batch file
imagetool -nobeep -nomip -dxt5 -dds -nodither *.bmp
you will need the above in a batch file and a copy of imagetool in the same folder,This will convert all bmp's in the folder to dxt5 dds

This batch file is fine for the main texture and the spec maps but dont use it on bumps

Spec maps are pretty straight forward,the color part handles the color of the highlights the alpha handles the strength.

this pic is of a mild blue in the main section of the texture and an all white alpha channel

this pic is the same blue but with a black alpha channel

you can mix the colors and the alpha channel to suit the color of the part and the saturation/strength via the alpha channel. So metal more white,painted wood darker gray or black,for flat surfaces black and black give the best results


Bump maps are the most time consuming
As far as I know there are only 2 plugins that work,the Nividia plugin for abode's paint
http://developer.nvidia.com/object/photoshop_dds_plugins.html
and a plugin for gimp, as Im a cheap sod I use gimp and the plugin
http://davenunez.wordpress.com/2008/07/21/using-the-gimp-to-create-bump-maps-for-fsx/
the above gimp tut has the links to gimp and the plugin.
In the above tut I only go as far as the flip part(I dont do that) after I click ok to make the normal map, I then save it as an unfliped bmp
then I run it through this batch file using imagetool
imagetool -nobeep -nomip -dxt5 -RedInAlpha -dds -nodither *.bmp
which fix's all the alpha channels and flips the texture.
The basics for bump maps is for flat surfaces use mid gray 128,128,128,full raised white 255,255,255 fully sunken black 0,0,0.any thing in between is a fraction of lift sink.
Here is a pic of a basic panel and rivet line

anyway hope this helps,its not the be all but how I understand it
cheers

And just to clear things up, those are made by the guys at McPhat Studios, and those guys are true artists.

No one makes worn and weathered paints like they do. Their upcoming UHDT paints have some things that I have never seen before in flightsim. For example if the diffuse map has part of peeled paint in it, the peeled part has its own specular and bump to replicate the baremetal peeking under the paint. The ding actually reflects light differently than the surrounding paint
