This document can help you to resolve problems related to OpenGL that occur while you use After Effects. OpenGL problems can manifest in many different ways, including (but not limited to) the following:
- Adobe After Effects crashes or closes without an error while it starts.
- A crash or freeze when you scrub the timeline or preview or render a composition.
- A crash when you change the settings of an effect while OpenGL previews are enabled.
- A crash or freeze when you enable or disable OpenGL previews.
- The composition window takes a long time to redraw.
- Artifacts or blocks of "garbage" pixels are drawn in the composition window.
- The composition window is drawn differently between when OpenGL previews are on and off.
- An error message such as one of the following:
" After Effects warning: A problem occurred when processing OpenGL commands."
"The instruction at '0x00fe1940' referenced memory at '0x000000000' The memory could not be 'read'."
"AE_OpenGL: failed to generate shadow map (5065::0)"
"This composition is too complex for the OpenGL hardware."
"After Effects error: AE_OpenGL: Create texture error. (5065 :: 0)"
For information about how to configure the preview preferences in After Effects for OpenGL and a list of features in After Effects that can be rendered with OpenGL, see Render with OpenGL in After Effects Help.
To benefit most from this document, perform the tasks in order. Record the tasks that you perform and the results of each, including errors and other problems. Adobe Technical Support can use this information to better assist you if you call.
It's necessary to log on as an administrator to perform some of the procedures in this document.
For Windows, some of these procedures require you to locate hidden files and hidden folders. Some procedures require you to locate files by their full filenames, which include extensions (for example, example_filename.ini). By default, Windows Explorer doesn't show hidden files, hidden folders, and filename extensions that it recognizes. See Show hidden files and folders in Windows for details.
For Windows Vista, the steps in this document that mention the Control Panel are in reference to the Classic view. For information on switching the Control Panel to the Classic view and many other common OS procedures, see Common OS procedures.
These tasks can help you resolve the most common problems with OpenGL. Before performing any of these tasks, back up all personal files (for example, After Effects files you created). Always restart the computer after a system error occurs to refresh its memory. Continuing to work without restarting the computer can compound the problem.
