Well since I am chillin with a drink in my hand and nobody has responded I thought I would drop a line or two.

It’s a great demo of webgl/threejs.

Can you do this in Verge3d to the same level of interactivity and quality – sure you just need to know JS and threeJS and understand the principals to the level the author of the demo knows and you are set.

Alternatively you can hire a dev that has that skill set but it will be expensive.

A inexpensive alternative would be to fake it.
The map you use for creating water surface normals can be modified to use as caustics. Animating the material over time will produce a quasi similar effect.

to change a color of an object in V3D there are a few options:

You can assign the object a new material.
You can assign the object a new texture.
You can use a value node in your shader and adjust the value node via puzzles.
You can use a mix shader node and value shader that influences the factor of the mix shader node.

There are other ways…too…just the way you were going about it wasn’t going to work.

Yuri makes some good points, but it depends on other factors too. If you are a freelancer, why pay for 3D software you don’t need. Max is $1875 per year per seat in the US. Blender is free. If you are a business owner…. 10 seats of max $18,750 per year….when it could be zero for the same output? No brainer there. As a freelancer you also have to consider profit vs expenses…need to hire a freelancer to help you out on your project….Maya and Max artist will cost more than a Blender artists because of the cost they have to pay to keep their software up…not necessarily because their work is or isn’t any better.

If you are a 3D artists already, making the switch to Blender is simple and free too…lots free online tutorials. Once you get the basics of it you are on your way.

However, if your current pipeline is Max or Maya, making the switch can seem daunting but you are about about to enter V3D in which you will need to rely on tutorials and this forum at least in the beginning.

Just take a look at the number of threads and the frequency of the threads between Max, Maya and Blender. The frequency of Blender threads is far beyond the other two combined…and the frequency and wait time for someone to provide a response is much shorter on the Blender side. Some of this difference is due to the maturity of the blender version but just roll back a few days/weeks or months and you will see the biggest reason to go the Blender route.

I am a Max, Maya and Blender artists / producer and for V3D projects our v3d teams are strictly Blender. The reason isn’t just the money its also the ability to know you can migrate your older files forward to any version of Blender. If you have clients that stick around for years this is a game changer.

Another vote for Blender far better suited for V3D. Not to mention its free.

The below image is a super simplified way to use hide/show.
Create a scene with a cube and a sphere, so that each object is outside of the other, no interference. Add the below puzzle and you can click on the sphere and see how it hides the cube.
