Can Texture Packer create irregular shape？

shan

If the package picure is a long rectangle with about 30 degeee. the packaged texture map will include mass of blank area which is wasted In two corners.
Is there any features or ways to slove this problem without rotating the source image?

Besides,if i can determine edges with mesh and record uvs in the json,can i record them in the atlas to tell the program how to use the image with irregular shape?if the texture image can divided with irregular shape instead of only rectangle,less white blank will be wasted.

And the last,Texture Packer can rotate images with 90 drgree now, but if it can be rotated with any angle according to the shape of the image edge,the resource size will be smaller.

woa nice art.

I believe it is because they are the actual size of the image, if you have a image 50px by 50px with a 1 px dot in the middle, it is still a 50px image. There are some options for texturepacking, but I am not well versed in spine anymore 😢 so cant offer much information.

The Spine TexturePacker will always pack rectangular regions.
But if you use Spine PRO, you can combine/arrange the images yourself and each rectangular region can contain several pieces. Then you can separate those pieces by cropping them using meshes.

If you don't plan to animate these in Spine, there are probably other packers that can do this for you. (tight packing, and give you mesh and uv data automatically)

If you already have an external program that can do this, and you're using Spine PRO, and if you're inclined to automate it, you can interpret that program's output into a Spine skeleton json and import it into Spine as meshes and one big region.
