Title: Resizing large images (2d Sprite or NGUI textures)
Post by: Tatanan on July 17, 2015, 06:03:23 AM

I have an image very large (2000x1500)  which I use sometimes scaled at 30%.
I use it with 2D Sprites or just UI Textures, but when scaling it (to smaller), it shows it "ugly", without quality.
I don't know the verb in English for this effect.

How can I use large images without losing quality when using them resized to small?

Use POT (power of two) textures with size 2-4-8-16-32-64-128-256-512-1024-2048-4096-8192 on side + enable mipmaps.

The only way to "not lose quality" of images that were scaled down is to scale them down beforehand in Photoshop or similar.
