Problem with material parameter setting when importing datasmith runtime

I want to import the datasmith file at runtime. The imported file has glass material, and cannot obtain accurate material parameters.
After testing, I found that the main problem is that the lighting mode of the main material must be Surface ForwardShading.
The datasmith file I need to import automatically sets the material lighting mode. Is there any way to do this?

Try many ways. Finally, I found that only by changing the main material of the datasmith runtime can we achieve the required functions.
But it also solved the problem.
