Ive been having some experiments with textures and other things lately, and ive been trying to get a result similar to this. of course I have tried a lot of things and since I am relatively new to this it didnt turn out so well. from https://www.youtube.com/watch?v=imbIsNAvUpM&ab_channel=Polyfjord

If there would be no easy way around trying to do something like this, from older questions (How to create clear plastic? (Cycles)) it would be nice to know how to make this one. Nodes are included on this but in the newer versions of Blender, some of the nodes are not available. enter image description here

    Feel free to add a link to the old question. -- About the plastic shader of the old question, all nodes are still there in newer Blender versions (2.8+) => https://i.stack.imgur.com/uRxtf.jpg - The red nodes at the top left are Value nodes, the color nodes below are called RGB, and the blue ones are Math nodes. In the side panel of the Shader Editor (key N), you can give the nodes a custom label. And Ctrl+H hides/reveals unused node sockets (or use the context menu). – Blunder Feb 15 '22 at 03:49
  • Thanks, think im just really bad at lighting stuff since the product was much lighter than the picture and the reflections arent too great but thats my own problem – nerd pants Feb 15 '22 at 04:38
  • @nerdpants In the reference you posted (1st pic) there are two materials : a clear transparent glass and an opaque difuse blue material. The second pic is, I guess your attempt to reproducing it but you just used one material which is semitransmissive and blue. That's why it doesn't match. – mqbaka mqbaka Feb 15 '22 at 06:35
  • well...if no one answers here...you can still go to polyfjords site, become a patron and ask him for help (if he didn't provide the blend file) – Chris Feb 15 '22 at 17:54
  • The shader for the legs and the body of this "spider bot" looks like a simple glass shader to me. Add a Solidify modifier to the cube/body. If you want to have the spheres a bit rough like plastic you can use a Noise Texture node, and a Bump node. The camera of this reference image has a lot of Depth of Field, so it's quite blurred. Here a quick try: https://i.stack.imgur.com/AgcAz.jpg – Blunder Feb 15 '22 at 20:44
  • @Blunder: damn...that's good. would you mind sharing the blend file? – Chris Feb 15 '22 at 21:02
  • Gotta agree with Chris my small brain couldn’t make that and it looks really simple a blend file would be cool – nerd pants Feb 16 '22 at 04:48

The shader for the legs and the body of this "spider bot" looks like a simple glass shader to me. Plexiglass or acryl maybe?

To mimic the reference, add a Solidify and a Bevel modifier to the body (cube). The legs only need a Bevel modifier because they don't look hollow. Then use the Principled BSDF with Transmission set to 1 and lower the Roughness to make the glass clear.

If you want to have the spheres a bit rough like plastic you can use a Noise Texture node, and a Bump node.

The camera of this reference image has a lot of Depth of Field, so it's quite blurred. You can activate this in the camera settings. Lower the F-Stop value to control the bokeh effect.

For the lighting, try an HDRI with half strength and an Area light for example. In the example, the forest.exr is used that comes with Blender. It's located in the Blender directory blender/<version>/datafiles/studiolights/world.

Here is a quick try (Cycles):
