ometimes when I render, there will be large areas of red, or a certain part of the smoke is missing, or black dots and black spots will appear.:/

I wanted to use Python to position the model above the ground plane, but I encountered some issues

Firstly, I implemented this effect using Python Node .

But I want to use 'pythonexprs' instead of script in the transformer node.
So I modified the code.

He is still able to calculate the minimum Y-axis value of the point in the model.
But when I joined pythonexprs, he reported an error.


I cannot solve it and need the help of experts. My English is poor. If I say something wrong, I'm sorry.
