I got a problem when I do the transparency&cloud material and solid material.
please see my problem pictures below.
I tried 2 ways:
1, the 2 touching surfaces have no space
2, the 2 touching surfaces overlap a little bit, such as 0.1mm.
the 2nd way works better, but it still has some strange dot on the surface on the final rendering pics. see below.
Thanks in advance for your supporting.
Thanks for your quick reply.
I will try your method.
For this "liquid and bottle" 3D,
what is the right way to manage the liquid surface and inner surface of the bottle?
Exactly touch? or cross each? or leave a small space between them?
