Mia material and transparency

[mary-poppins]

Hi,

I would like to make a pool like thing in a sill. I made a test scene, and I used this tutorial to make water with mia_material.

The mia_material attributes

Here is the test pool. Then I export the material and import into the main scene, but the transparency doesn't work Here it is.

I have no environment, so it is completely dark, but I created a yellow cube in order to be able to see reflection. Even if I turn off the caustics in the test scene, the transparency can be seen clearly in the test scene, but not the main

Any advices are appreciated.

Thank you

And your trace depth is sufficent or set to default preview?

Thank you for your answer. It should be high enough (refraction 10), because if I replace the mia material with a simple maya shader, and make it transparent, then it works.

The water material has a solid option (the surfaces should be have a proper exit/entry) in advanced refraction, and I use a simple plain for water, but if I change to the thin walled the caustics doesn't work again. So I leave this solid.

I found something. I replaced the pool itself with a simple extruded cube, and it works, the water transparent and has caustics. But I can't understand what is wrong with the sill. It has a displacement map, and mentalraySubdivApprox, and its material is a blinn with displacement in its blinnSG.

I really worked hard on displacement map, so I would like to use it.

Ohh, the visible in reflection and refraction options can work a miracle... Don't ask me why I turned it off... Maybe I just wanted to test how it works, then I forgot it to turn on... Sorry  and thank you for your help.

Yes well that would do it.
