Epstein's torso steam drill help
Steve, David, Michael, Ben, Ant anybody... I'm still tinkering in Friday challenge from 5 weeks ago.

Excuse my crude machine drawing. In the sketch, the bottom left depicts the left side leg, only to allow the viewer to see the assembly. It should be flipped to line up with the assemble on the right side of the casing's main body (box that the drill bit and mechanism would slide up and down in)

I'm having problems envisaging the side leg assemble of the original steam drill in Epstein's Torso. I'm trying to recreate the assembly from the reflections, highlights etc but it is rather difficult. What i've come up seems to fit the bill. It would offer the operator a 2 way adjustment of the legs, in comparison to the other model's 1 direction.

Any ideas? Do you think an assembly like this would withstand the ware and tare?

If constructed 'beefy' enough, I would think that it could last through the warranty period.

This below I found in during a different search, I thought it was interesting to watch...

Re: Epstein's torso steam drill help
I am not sure that one should assume that Epstein was interested in truly functional viable mechanics as much as just an idea. It is perfectly possible that his design might not necessarily be mechanically sound.

Re: Epstein's torso steam drill help
Thanks Iwc. That robot actually looks like it's along the same principles.

David, you have a valid point. The top of the legs look awfully like galvanised water pipe connections. I think i'll run with that assembly. If it looks right, they'll stay. Thanks.

Re: Epstein's torso steam drill help
I seem to have worked it out. Now for the sliding mechanism and working parts. That should keep me busy for a while.

Re: Epstein's torso steam drill help
Thanks David. I've hit a road block though. Studying the working mechanism, the housing and guide body is the incorrect shape. I'll either have to adapt or re-model it. I'd like it to resemble the original and have it appear as though it could actually work but damn, it's a lot of work. 2D is so much more relaxing. At least when you have a section that is unclear, you can disguise it but not in 3D. I'm trying sub-division modeling which prefers a mesh consisting mostly of polygons (4 sided shapes) You can use tri-angles but away from edges etc. As soon as there is an Ngon (5 sided shape) the sud-division of the mesh leaves a hole or disfigures the surface.

I suppose if I want to improve, I have to persevere. I'd love to finish it but after so many hours, weeks etc, then what? I'm a bugger for punishment aren't I. Hopefully i'll be able to display the completed model 1 day.

Re: Epstein's torso steam drill help
Yes well given my knowledge of 3D there is not a lot I can say. Aside from being quite expert and fast in Sketchup (which is principally for architects and designers and produces 3D drawings as opposed to photo real renders) my knowledge of 3D is extremely limited.

Very best of luck Dennis .........

This is why artists should not do 3D. Far from finished and i'm already texturing it...over and over, for best results...lol

I am extremely impressed!

Re: Epstein's torso steam drill help
Thanks Loyd and David. As David knows, I use Daz Studio a lot. I like the ease of setting up a scene in Daz and the many available models available for the program. I haven't however, been able to master the iRay surfaces in Daz, especially the metal.

Whilst modeling the steam drill, I periodically attempted to replicate what 3D coat was able to, in Daz. I love how 3D coat textures a metallic surface but I just could not apply them in Daz, until today.

There's pros and cons with both packages but damn am I a happy chappie. I'm actually very impressed with Daz's render. Absolutely no post work. Both renders are as the programs rendered them. Due to energy saving PBR surfaces, both rendered in under 2 minutes.

Re: Epstein's torso steam drill help
I am particularly impressed by the lighter worn edges. Without getting too technical, how did you do that in a render? It's the kind of detail I would add afterwards by hand in Photoshop.

In 3D coat and I imagine Marmoset, Substance painter, Quixel etc, you can attract your texture to certain areas of your model. (Shadow, lit, flat, convex, concave etc.) You can combined alpha maps with depth, shininess etc within layers, like masking areas per layer in PS and have multiple layers with different constraints applied to them, reacting with other layers, similar to what Photoshop does with blending mode.

All maps are combined to reflect what you have applied to your model in different classes. Albedo, specular, bump, roughness, metalness, gloss etc. Then in your 3D program you apply these maps to the relevant layers. If you combined them properly, you can achieve some very realistic surfaces. Time to have a look at Daz Studio again David. The introduction of iRay has been a great leap in the right direction. Using the same methods as above is offering pretty realistic skin tones as well. Maybe i'll be fortunate enough to work the skin layers out one day. The dermis, epidermis and hypodermis can be replicated with transmission, sub surface scattering, top coat, emission etc. I've seen some really impressive renders. The camera has many new setting as well.

Re: Epstein's torso steam drill help
These are the maps I used although iRay doesn't use the ambient occlusion map but if you invert it and use it in diffuse weight or roughness or anywhere it has an impact, it makes it appear as if there is dirt in the low places. I use it with the 3delight surfaces before I convert my model to iRay.

Re: Epstein's torso steam drill help
Daz Studio can now create a geo-shell, a skin that covers your whole model. Depending on the zones of your model, you can turn the transparency of those zones to any percentage you want. You can dial the shell to below or above the surface of the model. So after you have textured your model, you can improve it, apply decals, tattoos, water droplets or alpha maps with sand, dust, scratches etc.

Once i'm finished with the steam drill, i'll apply one of these shells and apply dust. I tried it already and it really finishes the model off. You can also have multiple shells.

Re: Epstein's torso steam drill help
OK. Thanks. I get the general idea. It's a huge amount of work. Well done!

Re: Epstein's torso steam drill help
Not really. Not once you know where the maps should go. 3D coat, once you have decided what surface you want, you apply it in 30 seconds. Save those maps and apply them to the surface of the model in the software of choice. PBR surfaces should work in any software that offers PBR surfaces.
