Troubleshooting
Some common problems we have encountered...
Nothing is rendering or the program is crashing when you load a stack.
Look at the Video card capabilities window. See what capabilities your video card has. If it says palette editing is not supported, please check that you do have a GeForce or Radeon 9600 or newer video card and make sure the driver is current. If it still doesn't work please let me know and share the details of your system. I don't have every possible combination of hardware on hand so user feedback is important.
Certain menu choices are greyed out.
If your video card does not support certain OpenGL extensions, the feature which require them will be disabled. You can see what you video card supports in the Video card capabilities window.
I get a white box while doing 3D texture maps.
For 3D texture maps to work, the image stack must fit entirely on the video card. Multiply the nearest greater power of two of the dimensions of your stack together. For example, a 400x400x400 becomes a 512x512x512. Then divide by 1024 twice. If that number is greater than the amount of memory on your video card, you need more video card memory to use 3D texture maps. Also, currently the largest 3D texture map allowed on a GeForce-based boards is 512x512x512.
I tried saving a snapshot / movie and no file was created.
Make sure you have write permission and sufficient room on the drive you are trying to save. The movies are uncompressed and get very large very quickly!
I'm editing a palette, but I do not see any changes on screen.
Check the stack manager and make sure the palette you are editing is assigned to a channel in the current volume. Also if it is a multichannel volume, make sure the alpha on the other channel is not too high. With a high enough alpha one channel can block out another.
