I've improved the workflow, so now I've sorted out the issue of shoes always getting scuffed on the ground. The next project is in the works, and the results for the shoes should be even better!
btw,I haven't updated for a long time because after switching to the Intel platform, my computer kept encountering various issues during rendering. This led to a frustrating 8-month period where I could hardly perform any medium to high-intensity work on my computer. After spending almost the amount it would take to buy a whole new computer, I finally resolved the issue. Intel sucks.
