I'm really new to Zmodeler3, and please forgive me if this is a dumb question😅.
The problem is that I am currently using OfficerUnderwood's DEV CVPI, which is really a masterpiece. I was able to fix some small issues, such as the middle brake light not lighting up, but the problem of over-transparent tail light lamp shades remains unsolved. Especially when the tail lights are facing the sunlight, the lamp shades become almost completely transparent, which is shown in the screenshots. I've seen other CVPIs released on LSPDFR.com which also use this base model, and their tail lights are much more appropriate. I've tried adjusting the parameters of transparency in Material Properties, along with other attempts, but nothing seemed to help. I would really appreciate it if anyone can point out what parameters to adjust for me. Thanks in advance!
So I finally found the solution, which is simply texturing issues. My Bad.😓
