Known Issues

Whilst Maya has cameras for the front/side/top and they are listed in HDR Light Studio's Render View that shows the Arnold IPR. But those views are not supported by Arnold. If you select front/side/top camera views in the HDR Light Studio Render View, the view will not change and the LightPaint feature will not function. The reason is that whilst Maya will list them as cameras, Arnold does not recognize them as cameras.
