Vray for C4D help


Hi there !

Need help for texturing this…

I am working on those Iron Man shaders, but I think I’m far away from what means “realistic render” (view joined image)

My gold material seems good but something goes wrong, and idk what, can you guys tell me maybe what can be improved ?
I think have a poor lightning, how do you guys light your render scene ? I did t it by a simple HDRI dome light but the result isn’t good at all any advice for this would be great !

And for the red material, its not finished at all but idk how to achieve something like this https://www.youtube.com/watch?v=jlw7-J2ZJVk, any suggests ?

Thanks !
