I kinda got to the point where I am happy, but those render times are just insane. My scene renders more than a hour on a FHD picture and still comes out pretty noise. I attached the material in a test scene.
Has someone tips to get those rendertimes down, or is that just impossible with such a look? We are using VRAY CPU at work, would the GPU renderer be faster?
Why don’t you activate the denoiser? you will get clean image in a fraction of the time. Personally I prefer the Intel open image denoiser that is very effective on both noise and fireflies.
For the materials, those should have SSS on the inner body (I use a simple 2sided) and for the exterior shell a semitransparent plastic shader should be enough, your original setup seems more complicated than it should be.
Here is my attempt based on this reference: 新浪网 on a modern system it should take no more than a couple minutes (you can find the HDR on polyhaven.com):
