Introduction to Maya - Rendering in Arnold
This course will look at the fundamentals of rendering in Arnold. We'll go through the different light types available, cameras, shaders, Arnold's render settings and finally how to split an image into render passes (AOV's), before we then reassemble it i

How can I make a rectangular fish tank in Maya?
Does this have something to do with a prism? Or would adding a certain refraction value to the water object make the mirror effect possible?
This probably could have been easier if I didn't forget most of the physics lessons from high school... -.-
If someone has done this before or similar projects, can you tell me how, please?

Then apply the appropriate acrylic material with the proper index of refraction.
Now the water is another matter and requires some use of particle systems either within maya or a third party application like realflow or SoUP.

I tried to use my tank for reference, but it's too long to catch all sides.
But the water surface and right facet are acting as a mirror, reflecting back 100%. The back is transparent because the camera is looking through the front facet. It's that effect I want to replicate. The reflection that happens only under water and not above water level, where all facets are transparent.
So if I'd put for example a cube inside the tank, and the cube has a different refraction level than the glass, will it cause the glass to appear like a mirror? But then even the water surface has to reflect back 100% while looking through the side facets of the tank.

What you need is a materials and fluid effects and lighting person to help with this.
If the materiel properties are set correctly on the acrylic and the water in the tank as well as the lighting the physics engine of the renderer should do the rest. Getting all the settings dialed in though, especially using MR, can be a bit of a black art.

What if I make the water out of a cube (since it's supposed to be non-rippling water) and place it inside the tank, but set refractive index of the cube to be different from glass refractive index? I think I remember a refracting object once produced mirror-like reflection inside itself, but not sure if it works like this. So only one way to find out.Yes and as I mentioned above that is all going to depend on your material properties - primarily IoR and fresnel, then lighting, and the accuracy of the physics model within your rendering application.

Well... so far, I've got the tank, and a refraction problem at the base.
Though I have used the refraction index for acrylic glass (1.490)...

Aaaand the result is:
Yes, the cube can act as the water. But I need to set it properly to touch the glass while not going through it...
Lol @ the ball at the top going through the water surface...

Refraction isn't quite working like I've expected. The bottom glass sheet is showing the wall instead of being green.
The water is taking a dark color when it meets the glass.
And the tank corners cannot appear where the cube's corners are. It just cuts them off.
Uhh... I left the water running...
But anyway, is there any liquid simulation in maya that can be held in a container? This one's ridiculous...

I cannot seem to get the hang of the container+emitter as it emits nothing... I think I am searching the wrong stuff on google too, as nothing seems to pop up when I search for creating water in maya, just fire used as fluid, which isn't what I am looking for...

That's not going to work... refraction is a factor, then there would be the need to continuously change the mirrors around with the camera angle...Fake it, put mirrors on the side and back some light fog and a few god rays for good measure..............dave
Someone on this forum posted a link to this: https://area.autodesk.com/blogs/dunca...ith_nparticles
The way the water sits in that first glass seems pretty close to what I want. Even if the water will not be moving, it would be much easier if I could just... pour the thing in a container and let it take the shape of it...
But where do I start? I am looking at nParticles... but not sure what I have to choose...

Now I need to figure out how to render them, as they cannot be rendered yet.
