Sprite Sheet Maker?

Unity Engine
,
1

Hi Guys- I am looking to automate the making of sprite sheets with 24 bit imagery in it. Basically I am looking to input/load each separate image sequence (if it can do batches that would be even better!) and create one sprite sheet with a series of images in it (it must retain transparency)

Can anyone recommend a program that does it?

I am sick and tired of laying them on sheets by hand.

:shock:

spriteworks - search for it using google.

I’ll Check it out

If you are already using Photoshop, you can fairly easily set up an action to do this.

What I do is, in Bridge, select the whole TGA sequence and select the menu option to load them into separate layers in a PSD, then run the action to lay them out once you’re in Photoshop.

I never really setup actions :sweat_smile: LOL but I will look into it immediately-

…is there a specific action to lay them out? I dont know that…can you describe it a little bit more

or you could use the Sprite Atlas Builder Unity Plugin

imagemagick allows you to create sprite sheets from the command line.

See last post on this page:

Problem is- I am creating sheets with transparency and it looks like the sprite builders that I am using do not take into account of the images actual size- so its looking at strictly the image information instead of the overall dimensions of the image.

I have checked out a number of different sprite sheet makers and they all have the same result so far- I will check out the imagemagik

If you render the sequence as TGAs with alpha or something similar then Photoshop will handle them fine–retaining alpha and respect total canvas size.

You just have to open the actions panel, record a new action, and do it by hand once. My action is something like this:

  1. Resize canvas to 1024x1024 (pinned in the upper left)
  2. Select layer 2
  3. Filter → Offset → 256px horizontally
  4. Select layer 3
  5. Filter → Offset → 512px horizontally
  6. Select layer 4
  7. Filter → Offset → 768px horizontally
  8. Select layer 5
  9. Filter → Offset → 256px vertically
    …
  10. Select layer 16
  11. Filter → Offset → 768px horizontally, 768px vertically
  12. Flatten image

From this point, depending upon your needs, you may be done. Since I was using filtering on compressed textures, I CMD-clicked the new collapsed layer with the layout and used that to fill a new alpha channel and then painted in a new layer behind the sprite layout so the border pixels would blend with a color instead of just white.

This is what I use to create spritesheets combined with the Bridge trick mentioned before… It is good to know that PS can use javascript… :wink:

Also this one might be handy if you don’t want to use Bridge as it is a resource hog. See comments in the above link to see how to edit the script to preserve transparency.

Cheers.

I could give you what i made if you want.

WOW thank you :slight_smile: i search something like Filter → Offset ! The problem is its using the local position. So all layers must be at position 0/0 at the beginning. How can i do that?

another problem is that the sprites must have exactly the same border(bounding box)…thats a problem because if you have for example a man who is moving his hand, the borders(bounding box) will be different in some frames… hmm :frowning:

SpriteManager 2 gets around this problem allowing non-uniformly sized sprites:
