Sprite Sheet quality problem

[Falrinth]

The "generate sprite sheet" function compressess the png hard.

Is there a way to make it not compress it and generate lossless spritesheet?

I use settings for output: png32 but the quality looks like jpg compression. Its ugly.

The automatically generated atlas for animation when i publish it to hmlt5 canvas, is lossless and great quality, but when i use "generate sprite sheet" from movie clip its quality is bad. How to fix it? It can be done for sure, if atlas is good quality.

Im attaching screenshot so you can compare atlas and spritesheet quality.

PNG is lossless. But, it will be taking the image based on your Library settings. Check the bitmaps in the library to see if they are set to lossless, and allow smoothing. Also, were they imported as PNG or JPEG?

Thank you for quick reply.

Well, they were imported as png sequence, published using Blender. I have quite a lot of them, so going trough each and every one of them and changing settings to PNG from (DEFAULT) JPG would be hassle to big for me to do. Would rather look for other software to do this smart way.

Is there a way to change default settings for imported bitmap to PNG publish settings? Even some harder way, like manipulating some Animate's files to achieve this would be great.

You can select all of the bitmaps in the library in one go, then click the i button, and change all of them to lossless, allow smoothing, in one step.

Thanks a lot! Didnt knew i can change settings for multiple items in library with one action. You saved my day! Cheers!

BTW, if you are doing HTML5 Canvas, or if you are taking the prefect exported PNG into another tool, you can optimize the image after you have published. Look at sites like tinypng.com. That can reduce the file size a lot, without ruining the image.
