Resin Gun Prop Sculpt

Hey folks!
This is my current piece, which was meant to be a quick project but, as I’ve started it, I’ve realised that there’s a lot I want to do…
The first image is just a couple of renders from the ZBrush concept, which I pulled together in about half an hour. It’s not very detailed, but I just wanted to get the forms and masses worked out.
The second shot is of the core of the actual sculpture.
I printed out the side-shot render from ZBrush, scaling the width of the hand grip to 4cm in Photoshop (that’s the distance between my right index finger and the base of my thumb), to make sure that the prop ends up being the correct scale. I then used some spare modelling foam (dense but very light weight to keep the weight of the sculpt down), traced out the outline of the weapon and cut it out with a craft knife. I then sanded it with my trusty mouse sander to try and get it roughly into shape.
The third shot is my current progress, with Monster Clay added over the foam core and sculpted, then buffed smooth with my *amazingly advanced* tools… which, as you can see in that image, is a small pot of white spirit, a scouring sponge, a hog bristle brush and another very fine brush to get a good polish in the tight spaces where I can’t use the back of the sponge.
The final piece will be moulded and then cast in resin, with LED lights inside and a power switch that will act as the trigger, but…
I need the piece to be hollow, both for weight and so that I can add the lights, wires and batteries inside. To give me reasonable access to the hollow innards, I need to cut the sculpt into two pieces, mould and hollow cast them separately, then slot them together when they’re both complete.
This is taxing my mind-brain.
In my head, I can visualise the structure that I need to do this, which looks like a ‘groove and slot’ arrangement in foam or wood, and I’m planning to use magnets to lock the resin cast pieces securely together.
I don’t want to have to cut it up, though, lol. My anxiety is running at volume 9. I think a hot wire foam cutter should be able to do the job smoothly, as long as I’m careful working along some cut-in seams that I still need to add.
This is a lot of fun. I’ve never sculpted and cast a weapon before, and pushing myself to get a good machined look feels really good. It’s going to look damned fine… I hope 🙂

Grey Head… Done!

Posted in Design, General, science fiction, scifi, sculpting, Uncategorized with tags , , , , , , on June 6, 2018 by Jim St Ruth

He’s finally done!

Sculpted in Monster Claw, then moulded in Platsil Gel 10 with an Easyflo 120 resin mother mould that was thickened with Polyfibre II. Then slush cast in Easyflo 120, primed and airbrushed, with two acrylic spheres for the eyes that have white LEDs hot glued into their backs.

The electrics are comprised of 4xAA batteries in a battery pack, two super bright white LEDs, and a resistor, with the LEDs soldered onto small PCBs.

It’s taken me six months to complete him, but I’ve got a lot of other projects on the go, and so overall it’s only a week’s worth of work, most of which was evenly split between sculpting and moulding. The final piece is also my first full head-sized bust sculpt and cast that I’ve completed, and with some help from my partner, my first lighting project too.

I’m so proud of him.

I think I’ll call him Bob.

ZBrush Sculpt: Super-Secret Project

This will be one of my next physical sculpts in Monster Clay… but the reason shall remain a mystery, perhaps for some time…

Reptoid Sculpt

Part of a series of Zbrush concept sculpts that I might turn into a silicone mask.

The upload quality of the turntable video is pretty awful. It was recorded at 720P and the file on my PC is absolutely fine. Something I need to look at in more detail for the future, I think.

Attack Ship

It’s been a long while since I posted to my blog… Busy world, lots of distractions and a lot of home improvement.

I bought Substance Painter a few months ago, and have been blown away by the ease of texturing a model. With so many filters, so much control and a great ability to customise, paint and make a model worn/ dirty, it’s an exceptional piece of software.

The model was sculpted in ZBrush, then retopologised and UV mapped in Maya.

ZOriginal

Original ZBrush Sculpt

To allow for high resolution textures, there are nine different texture sets/ UV groups, each with their own materials assigned, set up as different objects. The component objects are then unified into a single object that now has multiple texture sets, and it’s exported as an .obj file; importing this into Substance Painter then allows for the different texture sets to be worked on. I’ve included a UV snapshot of three of these texture sets below for reference and, whilst one of them doesn’t fill up the space as efficiently as it might do, it did the job.

The modelling took far more time than the texturing. Completing the ZBrush sculpt was pretty rapid, and I was happy with the overall design. This was created via Dynamesh and then reduced from 5m polygons to 36k using Decimation Master. The model was then made live in Maya, curves drawn across the surface which were then smoothed to make the flow of the individual piece of the model in the next step more regular.

The retopology was then completed at a low resolution; only around 25k polygons for the whole ship. The borders of the model’s pieces were checked with smooth preview, before the next step in Maya.

Substance Painter doesn’t have an option for smooth preview, so to prevent any blockiness the objects need to be at a higher resolution. So the pieces were subdivided, and unwanted edges were deleted. The final object is around 100k polygons which, when imported into Substance Painter, made my machine run like a dog.

However, because I’d UV mapped in groups and created several texture sets, the various pieces can be viewed and worked on in isolation in Substance Painter, speeding things up considerably. It’s also worth pointing out that by cycling through the material options with the ‘m’ shortcut key, you can effectively turn lighting and shadows off, allowing the whole object to be visible with very little slow down.

I was going to take everything back into Maya to render… but the in-built renderer in Substance Painter does a very nice job using HDRI maps for lighting. Since this is just a static image, just some beauty shots of the model and no scenery or posing, I’m just going to leave it as it is.

NewCar1a-JimStRuth2013A quick update of the model. The exterior has been completely retopologised (thanks to the use of Maya’s Quad Draw function and lots of curves to help smooth out the edges and various interior pieces of the body panels). The front wheels now have brake pads and suspension modeled too. The textures are purely placeholders… lots of exciting stuff still to come: interior modelling, full texturing, the weaponry and maybe some exterior armor plating.
