Hi,
check the Cornea and EyeSocket materials, you need a Specular material with enabled Fake Shadow option in the Common tab, and also switch to Path Tracing kernel.

Thanks! a lot for the reply and the help, appreciated , i attached my screen shots for both, did changed it but nothing changed, may be do i need to change something in the node editor?

any suggestions? need help

As you can see, the preview of the materials is not correct.
Please, create new Specular materials with Fake Shadow option active, and replace the transparent/invisible materials.
Have you switched the Kernel from Direct Light to Path Tracing?

thanks Beppe, but yes they are specular material ( I converted to octane render materials) with fake shadow option and the kernel it is PT

I also just tried creating a new octane material and did al those but for some reason that black doesn't go away.. looks like I am doing something wrong but still couldn't figure it out..

Thanks a lot for the offer but I couldn't attach it while sending private message.. ,, gives an error " The extension c4d is not allowed."

Please, save the project with assets, compress the resulting folder, and share it via private message.

Hi, in the render kernel setting try decreasing the ray epsilon setting to the lowest possible value. This should fix it.
