There are a few restrictions on what you can create with Sapphire Builder.

One restriction that we would like to point out is that S_Layer should not be used in builder effects that may be used across hosts, e.g. between Adobe and Avid. Such presets will not be compatible. For simple compositing, you can use S_EdgeFlash with the flash widths and Comp Premult set to zero, and use Matte Use set to Luma. For 2-input compositing in other modes like Screen, you can use S_MathOps.

You can take a look at the other restrictions in the Online Help Guide.
