I've never known how much I've wanted this until now!

anime tiddies spray pls Ty >:3c

Downvoted and reported

Bugfix for 1.0.0.12, using multiple of the same image file on the same mipmap level would crash due to the resulting image not creating an additional output file. Oops.

Edit: Added another check in version 1.0.0.13 to warn the user that a width or height not being a multiple of 4 (while technically correct) doesn't work in Source.

this is really freaking neat

welcome to tftv, hartmann!

Can it make gifs in source games?

Thanks, glad you like it!

It can make animated sprays, from source images of PNG, JPG, or BMP.

You'd do this by having each frame you want saved as an image, and then drag each one in the order you want.

If you mean can a GIF be imported directly, they aren't supported.

there used to be some crazy sprays that only appeared at certain distances or something like that, typically a spy or sniper, anyhow know how to do something like that?

Yep! Spraymaker5000 can do that, often called a fading spray. You use the mipmaps to make them, since the lower resolution mipmaps show up at longer distances, you can make them show completely different images.

== Updated to 1.0.0.14
Some UI changes, hopefully improvements!
Replaced the GrumbleBox (the textbox that spams warning messages) with a collection of more useful errors.
Mipmap mode selector and fill buttons are disabled when there aren't any mipmaps.
"Save as" button disabled until all images are filled.
Added "Max Res" button that will find the maximum possible resolution for the given image format, frames, and mipmaps. Won't do odd resolutions like 512x256 since the user probably doesn't want that.
Progress bar is now slightly better. Without threading it can't be made more accurate.
Removed unneeded dependencies.

does it do animated spray?

Yep! You can make animated sprays with Spraymaker5000.

== Updated to 1.0.0.15
NOLOD is now enabled by default, as it allows for players with low graphics settings to see fading sprays properly. Thanks to an Anon for the info.
ALL_MIPS is enabled when the smallest generated mipmap is below 32 pixels. But it turns out sprays don't honour this flag anyway so it's pointless. Oops.
Now warns user when the minimum mipmap requirement of 32 pixels isn't met.
Removed unneeded language folders.

== Updated to 1.0.0.16
Added support for uncompressed formats grayscale L8/I8, grayscale alpha A8L8/IA88, colour R8G8B8/BGR888, colour alpha A8R8G8B8/BGRA8888. If your image's native resolution can fit within these the resulting image will look better!
Added warning about aspect ratio not being close to 1:1, since regardless of the spray's actual resolution it will be stretched to fit 1:1 in-game.
I wrote a wrapper DLL in C++ for crnlib to call directly from C# to not need crunch.exe. But, the performance hit was way too much to consider using, due to threading I'd guess. Not implemented.
Tested "Point Sampling" flag for pixel art but the results don't look any clearer, seems grainy instead. Not implemented.

nice program which is easy to use, nice. would recommend.

This website can do 1024x1020 pixel sprays: https://mishcatt.github.io/Mishcatt/
But crnlib (Spraymaker5000) and vtflib (VTFEdit) result in better quality: https://i.imgur.com/JikGay7.png
And Spraymaker5000 has more options~

== Updated to 1.0.0.17
Added "Point Sampling". Turns out my previous test was incorrect in some way. Use this option for pixel art.
Removed "Not Recommended" from lossless formats to avoid discouraging users from using them, I guess?
Small progressbar improvement

Here's an album showing the different scale modes: https://imgur.com/a/T9WEP

== Updated to 1.1.0.18
New features:
Autocrop
Scale modes: Fit, Fill, Stretch, None
Another small progressbar improvement.
Small UI changes.
Changed the default image format to DXT1A since the default Scale Mode is "Fit", so a transparent background/border will be default.
Notes:
Upscaling pixel art in-program doesn't look good due to lacking the Box algorithm.
Scaling is now done in C#.NET rather than crnlib, so it will be somewhat slower. This was required to enable the new features. Known issue: scaling doesn't mirror XY so borders will ghost... maybe I should have just used Imagick .NET instead of native C# despite the 13MB DLL dependency.

Added a new feature to "Install to" detected installed games. I think it should work for any game which has sprays enabled, but not every game listed will have sprays enabled.

See that here:

== Updated to 1.2.0.20
Fixed UI bug where the mipmap size warning would remain after turning off mipmaps.
Removed the soft limits on odd resolutions (ex. 512x511 A8L8) when not using DXT compression.
Added warning about Point Sample (pixel art) not supporting mipmaps.
Added "Install to" feature which will automatically import the sprays to each of the selected games. Note: Not all games listed will actually support sprays.

== Updated to 1.3.0.21
Forked https://github.com/DaemonEngine/crunch and made some changes.
Performance and quality improvements:

Added autocrop, scale modes, and background compositing to Crunch, instead of doing it in C#.
Now includes 64-bit Crunch binary.
Pixel Art checkbox now sets scale algorithm to Box. Should maintain pixel-ness better this way when scaled.

== Updated to 1.3.0.23
Fixed a bug causing Spraymaker5000 to crash on start if it fails to find game paths
Added a transparent black colour and set it as default instead of transparent white, so borders on scaled alpha images are less dark.
Set the resolution inputs' maximums to 4096, as any higher gets clamped to 4096. Though that's way bigger than any spray could be anyway.
Added GameBanana link to contacts

The small spray pic in my multi-player option goes error when i put a space in spray name
please solve my problem :(

Dont put space in the name?

i did it before but i'm just lazy to type underscore

how to create a fading spray?

put different images in the different mip levels

are you saying it to me?

i'll try this
