Sprite editor large image bug

Hello,

I have a problem with the sprite editor.
I have a big spritesheet (1080 × 17280) and when i want to access the sprite editor with this image, it said “no texture or sprite selected”.
When i try with a smaller image (1080x1080) it works perfectly.

Is there a size limit for the images in Unity ?

Thank you for your help,
Maxime

It’s hardware dependent, but 17,280 is quite large for a texture. I wouldn’t generally recommend going over 4096 or 8192. At one point hardware didn’t support textures larger than 8192. Also, dimensions should generally be a power of 2 to maximize compatibility (although that may be outdated knowledge).
