issue regarding image file sizes
When I look at the image size in finder or documents, it usually says something like 23kb for a 3200x1600 image. But in unity when its uncompressed it says its 17mb. What causes this jump in size? How can I compress images without getting skewed looks or odd gradients?
I cannot see that the GPU using anything but uncompressed textures. So uncompressed:
3200 1600 3 = 15,360,000 = 14.64 mb. If you have an alpha channel you are talking about 19.53 mb.
On top of this Unity does not handle non-power-of-two bitmaps efficiently, so some of what you are seeing may be there as well (true in Unity 3.x, haven't tested 4.x).
23kb? I think you're crazy. $$anonymous$$y old DSLR pictures were about that resolution and it was around 10mb filesize. I can't even get 250x250 files down to 23kb most of the time
