## 3D Graphics Window

If you encounter any problems in displaying MRI slices in the 3D window in Source Analysis, then it is possible that a graphics card setting needs to be changed. This is done in the besa.ini file. To change the setting:

Close the BESA Research program. In Windows Explorer, locate the besa.ini file. For the example of a BESA Research 6.1 installation, in Windows 7 and Windows 8.x, it should usually be located under

C:\Users\Public\Documents\BESA\Research_6_1\

Open the file in a text editor. Towards the end of the file, you should find the following section:

[Mapping]
UseBitmapDrawing=On
Use3DVBlending=On


Change the entry Use3DVBlending.

You can try three different settings. Choose one of:

Use3DVBlending=On

Use3DVBlending=Off

Use3DVBlending=Auto

One of these should work for your graphics card. The example below shows a 3D MRI slicing with blending set to Off and to On.
