Hi, there are a couple of questions about lenses with custom face shapes that I have not been able to figure out, so I'd appreciate your guidance.
1, I need to set my lens shape to "DoubleParaboloidLens", Do I need to rewrite cl_local_z and cl_local_n as custom face functions? as shown in the figure below .
(I think the XRT program relies on the text content in cl_local_z and cl_local_n to determine the lens shape, but I think the XRT program relies on the text content in cl_local_z and cl_local_n to determine the lens shape. cl_local_n to determine the lens shape.

2, I follow the tutorial to add a new module, in the new module to add new variables and change the face type function equation, successfully imported into xrt.qook, the generated script runs perfectly, but the program will prompt "Incorrect parameters , class customLens01 is not initialized" as shown in Figure 2 below. Is there a good solution for this situation.

Thank you for your guidance！
