Creating HD/SD Atlas from the same sprites

[nah0y]

Hi there !

It's not a question about how do you do to manage HD and SD.

In my project, I have all my HD sprites ready, and my HD atlases too. Now I want to make SD atlases based on the existing sprites. I don't want to manually go and clone the sprites at 50% of their sizes and then recreate the atlases.

Is there an easy way to do this ? For example, can I just take my HD atlas and clone it to 50% in photoshop ?

Thanks,

You can, sure. Switch the coordinate system to be texcoords on the atlas first. Downscaling the texture will keep your sprites this way.

A small warning though -- downscaling the texture is not exactly the ideal way to go. Going through your sprites and making 50% versions of them is the proper approach.

One solution so far, and I didn't see it existed, is to use TexturePacker.

(this is AWESOME that you support it, because we can do a lot more with it when creating atlases).

TexturePacker allow me to save two atlas version (SD & HD) in one export.

Thanks for the answer,

The problem is that we have a LOT of sprites and it will take forever...
I've tried what you're telling (and it's working), the only problem is that if I change my HQ atlas, I will also have to manually change the SD atlas too...

Also, instead of going through every sprite of my scene, I just create 2 new atlases (HD & SD) and then change the currently used atlas to "Reference" and link to one of the two new atlases.

Thanks
