EPIC GIANT TEXTURE - possible?

Question

Hi there..

I´m working on one large 2D Worldmap. The Picture Size is: 165888 * 64512

I don´t want to use it in that size - instead, i want to cut it into small 1024*1024 parts. BUT - i want it to be cutted with Unitys Grap$$anonymous$$cs.blit, and then save them as PNGs with a code i found in the Answers.

Now the question: Is it possible to read the giant texture, and use the blitting function?

I t$$anonymous$$nk you will need to use a different program for that.

Use somet$$anonymous$$ng like ImageMagick.

Or write your own program to stream the file, and save it in chunks.

Or do both. Write a program that utilizes ImageMagick's stream-command.

Sounds like Carmack's MegaTexture. Have you tried? Just try it. Importing from a file and sending to grap$$anonymous$$cs card are two different t$$anonymous$$ngs. You could write your own PNG parser and image manager, use OpenCV, etc. In short, yes, but you'll probably have to write the splitting code yourself. If Unity can load it, you can use GetPixels32 to access tiles-worth and create your own, and easily save those off as PNGs
