My custom badges do not export correctly to beamng

Hi I have an issue with my custom badge when exporting to beamng. The badges has more than one color including white. the rest is transparent. I have followed the tutorial on YouTube by hard rooster labs. His badge was more than one color and I was able to make it work in automation. However when I export it to beamng only the white area is showing. all of the colors are invisible. I have tried to use export parameters in the ue4 editor but could not figure it out. And nothing else has worked to fix the issue. So how would you fix this issue?
