I dont know why, i have these tiny dots on the lens of my orbot. I pluged 4K Textures in and rendered it with 500 sample.
thank you very much.
Hey acribit ,
Looks great, the white dots on the lens is noise from the glass. 500 samples is not enough when using textures that have refraction.
You want to pump this up quite a lot to reduce it and turn on the denoiser, try 1024 samples to start with, then 2048, 4096, until your happy.
Also under light paths in the render properties , check the number of bounces for transmission is high enough, if you have 12 as the total set transmission to 12.
Hope this helps.
