[Free] Nice Alpha Utility

If you ever used a texture with alpha information in 3D, you should have stumbled upon this problem:
Semi-transparent pixels are too bright.

You want this:


Now, you get it.

Istead of using a technique like this to get this result, you may now download the Nice Alpha Utility for free.

It will create a copy of your texture asset with it's alpha information "niced".
It's working faster than Dilation and, best of all, it's within Unity.
It copies Aniso Level, Filter Mode and Wrap Mode from the source texture asset.
It also has all the mipmaps of the original texture.

Download

It is available right here: Black Ice Games Development Download Page

Instructions

- Import the Package

- Open the Nice Alpha Utility Window by clicking Window => Nice Alpha Utility
- Drag a texture into the texture field
- Done!

- Alternatively, you can click on a texture asset and use it's context menu:


- Use the Suffix Property to have the new textures have a certain name depending on the original texture.

Stuff

I did my best to have this working fast and nicely, though keeping it simple to use.
Hope you like it.

Feedback, constructive criticism, or a Unity Pro License would be appreciated

 

when i'll be at he HUD state of my project this would be really needed. How does it react with materials ?. The example you show is a sprite, texture 2D or a plane with a tranparent material ? this looks nice and smooth. need some more explanations. sorry

 

Every transparent texture takes advantage when this tool is used, not only the hud

The way it works is:
It makes a copy from a texture in your assets. The copy will look good. That's all.
I wrote that in the first post now

 

well, for a creatures with wings a little bit transparent, if as you say it's a texture improver it should be a must have. grass, leaves etc will be improve the same way i assume ???

 

What you will get is the exact same image as if you'd use it on a website, for example.
No white aura around.

 

This has given me lots of grief in past, you are right. Thanks ever so much

 

Version 1.1 is out - Optimized some redundant mipmap handling code.

 

nothing found in that page. sure you didn't removed it?

 

You're right, sorry.
I reuploaded it.

 

I've been looking for this thread for a while now...
You just don't know how much you value a kit until it's taken away from you...

Thanks for re-uploading it.

TY. Have you yet gifted U3d with this utility? I guess it's a must have for them, also 'cause it resolves the issues of the built-in transparence system.

 

No, and for two reasons:
- My impression is that Unity 3.5 has most importers updated to autmatically fix this.
- This tool doesn't bring the desired effect in many cases - just when it comes to pixels which are too bright.

I tried to implement a dilation tool working like this Utility, but i haven't been successful yet.

 

There is a great write-up about this issue and a solution (for photoshop users) here.

Unity has its own tutorial for this: http://unity3d.com/support/documentation/Manual/HOWTO-alphamaps
