Concept Hybrid Amplifier

I am fortunate enough to own an old Beomaster 3000 amplifier, which I have added a chain of accessories to make it work through optical audio I/O. I want to get it to work with Bluetooth as well eventually.

However, before tackling modelling the old Beomaster, I thought I’d have a go at concepting a nonsense amplifier/stereo with a bit of an “internal” twist. Essentially, it is a few stolen electronic parts from my CPU render, to make a future stereo, with closer links to a PC (audio-post, on-the-fly effects processing…). However, I am also quite keen on physical switches as well, so I am currently almost done with the regular shape, but the front panel doesn’t quite yet work for me; so I think I’ll rehash. The large frame inside hosts 2x80-mm fans, used to cool the woefully large SPU (Sound) and CPU. I think the current switch material leaves much to be desired.

I’m having serious trouble with finding time at the moment, so these projects where I an do fast modelling and concepting are really fun.

Anyway, I hope someone gets some enjoyment from the WIP. It may not get finished!

This is Rhino 8 Cycles. Background here is Polyhaven Brown Photostudio.


Was this all HDRI lighting only? Can you show your set up?

Looks awesome! Thanks for sharing

Hi Scott, and thanks!

Actually there is not much to show. The lighting is HDRI, and a ring-light under the top cover (check the top of third image for the white band) that is an emission material; the only effect of which is to prevent black areas on the inside during the render. But the contribution from the ring light is quite low, with the HDRI dominating the contribution.

Gotcha , nice and simple. It looks great!

I also like the shallow depth of field.

Reworked material for outer case to use procedural GPU texture, preventing tiling, mostly important on the top surface. Buttons changed. I liked the big light switches, but i think they were a bit disruptive to the overall flow.


i thought there is some fancy pants tiling rotation system now in Rhino but not sure if that is for decals only, but i would love such an option for Rhino to make more seamless patterns. @nathanletwory would you be so kind and explain maybe i saw some recent post but cant quite figure it out yet.

Do you mean the mirror alternate tiles option for bitmap textures? That doesn’t do much to combat repetition:

sorry that was my mistake, i misinterpreted this topic because the checker tiling looked like this.

does not blender have such an option to rotate tiles? i believe i asked already would that be possible to implement in Rhino?

I am not sure I’m following .The topic you link to is about mirror alternate texture. This is what we support and what I am showing. It still will show tiling as I show in my screenshot.

yes i understood that sorry for the confusion once more, i only had a brief look and somehow i had the impression it was about rotating the tiles, not sure how i got to this idea, still would that be possible to do that at some point in Rhino?

just to be sure, by rotate i actually mean not just mirror, but rotate at any arbitrary angle if wanted, to mitigate tiling effects.

With the current plans for Rhino 9 you should be able to create shader graphs right in Rhino just as you want - that would include texcoordinate and mapping nodes. We’ll see how this pans out.


Equaliser added through various frequency bins.


Okay, I think I am finished with this product concept. I was going to add more, but I think that the cleanliness is balanced here, and I don’t want to add more for the sake of having detail. Also, I must be careful that the element of fun isn’t lost!


Looks fantastic. I love the subtle surface textures
