Pot Launcher

H

ere are screenshots of the next key mechanical model I've created for the F/V Scully, the pot launcher.

This is a major component of any crab fishing vessel. The hydraulic launcher is a powerful piece of equipment that raises and launches crab pots. There are various types of launchers that can both raise up to toss the pot overboard, as well as, tilt forward and shake crabs from a pot to a sorting table.

I struggled for some time working out what equipment crab fishing vessels had back in the 70's and whether a pot launcher made the Scully look slightly too modern-day in terms of technicality.

Sometime between the commercial crab fishing industries beginning in Alaska (back in the 50's) to its heyday (around 1980), pot launchers were introduced to fishing vessels to help speed up loading and offloading crab pots (empty pots alone can weigh roughly 800 pounds).

I did some research and eventually decided to make a basic single actuating launcher. The little hooks either side at the top and bottom are called dogs which hold the crab pot in place; also stopping a pot from swinging about when in rough seas.

Below, is a screenshot in Maya, where I have selected the back pivot brackets of the launcher. I found this part of the build to be the most challenging as it is not only where the pot launcher pivots but also connects to the bulwark (raised side walls).

Overall, I enjoyed creating this mechanical piece, stripping back the design to give it a simple structure more true to the time. Am quite looking forward to texturing it and adding weathering (as it is one of the most used pieces of gear on a crab fishing boat) at a later date!

Double-barreled Kriegsmarine Signalling Pistol Renders

H ello! After being away from blogging for almost an entire year (big life changes) I am finally back! Posts might not be regular every month from now on, but  D_ROGUE is still very much alive. Things are just moving a little slower, as well as a bit sideways...like a crab. As the title for this post states, I have created a model of a  double-barreled Kriegsmarine signalling pistol for the game! A couple of years ago, I visited The Royal Navy Submarine Museum. Amongst the fascinating history and artifacts on display, I saw what looked like a firearm. Upon reading the information plaque, it turned out to be a unique and very rare double-barreled flare gun from a  German  submarine.  These big-bad-beefed-up flare guns were used on U-Boats in the Second World War not only for signalling and when in distress, but also for lighting purposes. My interest peaked,  I took  several photos for reference thinking it would be a fun hard-surface model to recreate....

New Project

Hello! Sometime while at University, studying Computer Games Arts, I had a vision for a video game. This idea, from 2015, would turn out to become a passion project where I mused, jotted and doodled on the sidelines of studying.  It wasn't for a further three years until I decided to actually put pen to paper (or pen to tablet in my case) and bring my idea to life.  As the quote goes, "A dream is just a dream until you decide to make it real" or "All our dreams can come true, if we have the courage to pursue them". So in Autumn 2018, I did just that. Pursued my dreams. Now I wouldn't attempt to make a whole game all by myself. That would be silly and take literally years!  I lulled over the notion of asking fellow  graduates and  freelance artists  to aid in bringing my vision to life. This would be great but several factors including money and time played on my mind...alot. Then a marvell...

Hydraulic Crane Renders

I t has been over eight hundred and thirty five days since I began modelling the hydraulic crane (amongst many other things in my spare time) and I can finally say I have completed texturing it! This was without a doubt one of the hardest pieces of machinery to construct so far for D_ROGUE. Not only due to the number of parts involved (over one hundred individual pieces) but also the lack of any decent close-up reference. Almost every photo taken of a hydraulic crane, on board the boats seen in the TV show Deadliest Catch and elsewhere online, are either too far away or out of focus. I chose the F/V Saga crane as this was the most 'well-documented'. Eventually, it came down to just hours of staring at blurry images, learning all the major components, as well as a bit of creative licence! Here we have the final renders of the model below. I quite enjoyed weathering parts such as the hatch and lifting hook; adding a story with all the scratches, dinks and rust. I was careful not...
