Have you ever dealing with this?

When i load an image(sprite) which the size is so big about 3200px, the image wont show on the layout but when you run its show up?

It's not right to upload images bigger than 1024*1204 px.

So is that happen to you too?

Hi, would be good idea to search 'remember not to waste your memory', which is a blog written by Ashley. It will help you a great deal in the long run.

i hope someone could try to import big sized sprite like me and post the screenshot here? I guess its about my old graphic that cause the problem

You're better to break that into tiles that repeat (TiledBackground objects) and then position them. Smaller objects perform better as well as preventing that issue in the layout.

As for why it's not rendering, try zooming out in the layout editor, but that image is definitely too big and should be in smaller pieces.

In fact, here's an example of the tiles that can be pulled just from the screenshot

Your graphics card can't handle a texture that size. The image editor is software rendered, which it why it appears there. As said, don't use single images for levels. Break them up and use instances of sprites and/or tiled backgrounds. https://www.scirra.com/blog/112/remembe ... our-memory

4096 x 4096 textures (that is what your sprite becomes in memory because its larger than 2048 x 2048) aren't supported on a lot of older GPUs.

Also. NEVER make an entire scene with 1 super large image.
