2d project from texture to sprites

Hi,

I have already done a lot of work in our current project and everything is just listed as textures in the project. I have no atlases or such in it at the moment. As I understand it with the new 2d support in Unity 3d, you are able to set the import settings to Sprite instead of texture now.

When I do this, don't I need Mesh Filter (I use a quad as it is now) and a Mesh renderer anymore? Do I just change the images from texture to sprite and drop it on to the object and remove the Mesh Filter and Mesh renderer and all will be good?

How do I use Sprite "Multiple"? Is that how you create an Atlas? How do I do that and how do I change my current project to work well with changing it?

As it is now we have the alpha channel in a separate file and combine the two files in a custom shader in order to support ETC. Is this still needed when doing sprites?

 

Sprites use a SpriteRenderer component, rather than MeshRenderer and MeshFilter. You create an atlas by setting a packing tag for the sprites you want to be part of an atlas (different tags make different atlases) and click Pack in the Sprite Packer window. Note that sprites in the Resources folder can't be part of an atlas, so if you're in the Sprite Packer window and the Pack button is greyed out, move your sprites out of Resources.

What is the Sprite Packer? Do you mean the Sprite Editor?

 

No, the sprite packer. http://docs.unity3d.com/Documentation/Manual/SpritePacker.html

What does it mean that my Sprite Packer is greyed out and says "Developer Preview"?

 

Look like that function is Pro only.

However if you pack your sprites yourself into one texture ( in photoshop ) the sprite editor will 'slice' them into individual sprites.

Sprite Editor should really be called sprite Atlas editor

 

Packing is automatic anyway, unless you have it disabled in project settings/editor.

Any idea why the sprites in the Resources folder can't be part of texture atlas?
