Corona Error Messages 59

• System is running low on RAM. You may experience excessive parsing times and/or crashes. You will probably have to simplify the scene
• Windows enabled 'Fault Tolerant Heap' for 3dsmax or dependent processes. This may have severe performance impact on Corona. Please follow the link to learn how to solve the problem. Affected executables are: xxxx (typically 3dsmax.exe)
• A normal map appears to be using input image with incorrect gamma. This can cause shading artifacts.
• You have 3ds Max bitmap paging enabled. This is known to drastically reduce performance of textures while rendering
• Required asset file could not be located
