Certain graphics drivers, such as newer Intel drivers, will cause some off-screen rendering issues that may not allow Voxler to export the 3D scene. If this is the case, at the time of export an error message will appear that says:

“Off-screen rendering failed. This may happen due to memory limitations, or problems with the OpenGL driver. Try turning off PBuffer support in Inventor.ini.”

If you receive this error message you will need to navigate to Voxler’s Inventor.ini file at C:\Program Files\Golden Software\Voxler 4 and open the file in Notepad or another text editor program.  Once you have the file open, the very first set of  lines under the header look like this:

          # Set to 1 to use pbuffers for offscreen rendering (if supported by the hardware).

          # Set to 0 to use the Microsoft software renderer.

          #UsePbuffers = 1

Change these lines to:

          # Set to 1 to use pbuffers for offscreen rendering (if supported by the hardware).

          # Set to 0 to use the Microsoft software renderer.

           UsePbuffers = 0

Once the changes are made, save the file from Notepad and restart Voxler; the error message should not appear.  If for any reason it does, please contact us.
