Simplygon Batch and SPL

In Simplygon 9, SPL has been replace by pipelines. You can either use pipelines from C++, C# or Python or via the Simplygon UI integrated into all our integrations.
In the Simplygon UI in Maya, Max and Unity you can import SPL files and they are converted automatically to Simplygon 9 pipelines.
Simplygon Batch in 8 is also replaced by the pipeline connect. You can now script you own batch script in C++,C# or Python with full access to our process distribution options.
Here is an example of a simple batch script using pipelines.

This example shows how to do batch processing.
