Make UISprite black-and-white

[elvess]

Hello.
Im using UISprite to render sprites. I have two sprites that are in the same atlas.
Is there a way to make one of them black-and-white without creating additional textures?

Thank U

A lot of times I make my sprites black and white and add a tint via the widget to make them different colors as needed.

There is no way to make a colored sprite black-and-white in NGUI. You'd need to write a custom shader for something like that.

Thank U.

We have shader that makes texture black-and-white. But shader is applying on material, and it will make all the sprites in atlas black-and-white. And I need to make only one sprite from atlas black-and-white.

You can specify a material override on UITextures / UI2DSprites, but not on UISprites. My suggestion? Use Unity 4.5's 2D sprites instead of an NGUI atlas. You will be able to choose whatever material you want that way. ALT+SHIFT+D to add a 2D sprite.
