Hi @123456_1 , I confirm that the effect is incorrect in V-Ray and there seems to be no way of getting the expected results. However, using V-Ray GPU, produces the desired effect, so we will investigate on how to fix it for the regular V-Ray as well. I will log an internal issue for further investigation.

Now I find that setting it up like this can work properly, but it’s obviously a bit troublesome
