In this case, a user installed the latest MtoA, but when he went to load mtoa. Settings/Preferences: maya.exe - Entry Point Not Found MAYA_RENDER_DESC_PATH = C:\solidangle\mtoadeploy\2013.0.22.0 And sure enough, it looked something like this: The procedure entry point could not be located in the dynamic link library mtoa_api.dll.įrom past experience, I knew that the problem was probably the Maya.env file. Notice that there are two MAYA_RENDER_DESC_PATH and PATH settings. For batch rendering, Arnold log messages go into mayaRenderLog: Windows USERPROFILEDocumentsmayamayaRenderLog.txt OSX /Library/Logs/Maya/mayaRender. Maya reads just the top two, which are for an older version of mtoa, so when Maya loads mtoa.mll we end up with a “missing entry point” error. How did this happen? Well, in this case, in-between installs and uninstalls of different versions MtoA, the user had updated Maya.env with his own MAYA_RENDER_DESC_PATH and PATH settings for MtoA. ![]() Uninstalls restore the backup version of make a backup of the existing Maya.env, and then append the environment settings to the existing then the next install of MtoA appended its own settings to the Maya.env file. So if your Maya.env already has MtoA settings for MAYA_RENDER_DESC_PATH and PATH settings, then when you install another MtoA, you end up with a problem (because the new settings will be at the bottom, where they are ignored). You can either add a regular Maya Area Light, in which case Arnold will assume a rectangle/quad source or if you require a different shape, you can alter the light node type to be an Ai Area Light. Just remove those extra entries from Maya.env. There are two ways to use an Arnold area light in MtoA.
