Hello!
I dont know if the other bidders had sent you any samples. but on my case, I had fixed your issue with the C4D file. Below, you will find a link to downlad a rendered sample (I had turned off Global illumination for the sake of render times.) If you choose me for the project, I'll send you the corrected C4D file. Thanks!
