Background:
There are some limits when it comes to importing textured meshes. Any image with an in-memory size greater than 2GB would cause a crash of the software, so we prevent it from importing.
This is not a limit on the size of the image file itself but on how much memory it takes Leapfrog to import it. This equates to a maximum number of pixels (assuming 3 channels) of 715776516.
We have various error messages which display when the texture exceeds the allowed size that should inform you what the width and height of the texture in pixels would need to be reduced to in order to allow import.
If the textured mesh can be imported then there shouldn't be a problem displaying it in the scene view as long as the graphics hardware is sufficient.
