Thank you for your response. We have recently encountered another new problem about SCM. When adding a fine-grained grid into the system, the redering efficiency would be low. Therefore, we need to perform a fine-grained grid only around the moving vehicle and other areas with low-resolution terrain, like the picture below. How can I achieve this effect?
