- Filtering has no effect. Arnold will always use its internal filters.
- Only bitmap formats natively supported by Arnold will work.
- The effect of the Blur settings may appear different
Unless you need to take advantage of the Bitmap's advanced parameters, it is strongly suggested that you avoid its usage, and prefer the Arnold image node. In addition to the above limitations, the wrapper can add many auxiliary nodes to support the Bitmap parameters that do not have an equivalent in the Arnold node, which can have a severe impact on the rendering time.
Consult the 3ds Max manual, for details on how all of the parameters work.
