Not 10 million pieces of 1024 * 1024 texture, but 10 million pieces of 1.24 * 1.24 texture, each of which is less than 1kb, all of which are 9gb in total. I have imported all UE5 asset managers and converted them into Sprite assets!
My problem now is that if every sprite is an Actor component, it will affect the performance, because tens of millions of components will cause the game to crash. So I need a grid image combination Actor, such as TileMap, which converts 10 million images or some of them into one image first. But I found that TileMap is only applicable to all images that are already on the same texture to tile and fill. But my asset is the filling of a large resolution image. So I’m looking for a grid that supports the definition of the number of rows and columns, as well as the pictures in cells. First, combine a large number of pictures into one picture, so that the whole scene has only one picture.
