Why is the node temperature rendering in lasso-dyna inconsistent with the actual rendering effect in LS-PrePost?

this is render in lasso-dyna:

<img width="1574" height="933" alt="Image" src="https://github.com/user-attachments/assets/1ae43968-8ab0-463c-affe-9fda26216527" />
this is render in ls-prepost:

<img width="2419" height="1055" alt="Image" src="https://github.com/user-attachments/assets/2f627e3f-7f8c-42d5-b7fa-47090fe95625" />
