Hello,
I need a few tips to optimize the render time for objects with a glass or xray material. What should I put attention on. Render times increase from 1 minute to 8 minutes per Frame just because of the material. The object is a machinery housing.

Best regards

Please, post at least some screenshots of the material setup and Kernel settings, otherwise it is quite difficult to help.
ciao Beppe

Hi Beppe,
sorry for the delay.
I´ve create a testfile with the settings and material. The original housing is much more complex but maybe you will find some basic failure the I made in the settings or lightning.

Thank you

Best regards

Hi,
I have a look at the scene, but I don’t see nothing strange.
A transparent material needs more resources/computation to be rendered.
You can increase the Parallel sampling to 16, and Max tile sampling to 32, to reduce a bit the rendering time.
It renders in 5’:21" with one GTX 1070 here, at full resolution and subdivision.

It is as it is, it`s ok for me to know that

Thank you very much Beppe
