Is there a maximum size a backdrop can be?

[natrey]

I am trying to create a frame 10000 * 8000
I load the backdrop image (a single picture painted by hand so not able to be tiled)
and all is fine...until.

I run the frame/application and the backdrop image gets cropped and im missing about 1 tenth of the bottom of the image.

Still cropped in the editor screen after running the frame?

you'll want to break it into much smaller pieces. Forgive me for not recalling the optimal size but 10000x8000 is too large.

You can use Gimp or some other app to cut that single image into smaller units and place them where they need to be.

Images are converted to textures. The size of the texture is the size of the image rounded to the nearest higher power of 2. Your image will be stored in a 16384x8192 texture (512 Mb in size :p). The texture size is usually limited, the limit depends on your video card. Better not use images larger than 2048 pixels and better cut them even in smaller images (512) to allow a better memory management and a faster display.

So once cut im guessing they would need to be loaded and destroyed when offscreen or i will have the same issue or performance problems?

Textures that have been offscreen during a certain time are automatically destroyed (in the build 284 at least), you haven't to handle it yourself.
