Grenade (Throwable 1)
After I had modelled all of the guns, I needed to make a start on the throwables as this would have a big impact on the gameplay. I settled with two throwables for the final game as I didn't want more work to slow me down. Two throwables felt like the perfect amount as one would be the grenade and the other would be a flash grenade. The first one I worked on was the grenade. I will showcase the process of the modelling side below on how I resulted in the final look. Unfortunately I didn't record the process of me modelling the grenade but I will ensure to showcase as much as the process I can to provide all the evidence and steps to making this grenade.
Modelling the grenade
The first step to model this grenade was to trace over a reference image that I had used from my mood board. I would create a quick block out over the image to get a rough shape I am looking for and then I would focus on creating the details such as the shell pieces. To create this part of the model I will select each individual face around the middle of the object and then I would offset each one so that there is a small gap in between each face. I would then extrude out each face and resize the tip of each extrusion to create the effect of the individual shells.
The next piece of the model I had to work on was the fuse. This piece would sit on top of the shell which I found to be one of the simplest models to create in this grenade. The first stage I had to start with was creating the back end which was a cylindrical shape which I had shortened the sides down to ten as the real shape wasn't perfectly circular. The next part I worked on was deleting the front two face and extruding the edges out which I then put the two front places back in place. I then created a swift loop near the top of the object as this allowed me to extrude out the back end for that overhang that is shown on the references images. I added another swift loop towards the bottom of the object to allow me to extrude out the bottom faces of the circular side as this was used to create a lip. The final stage of this process was creating the hole for the pin to fit through which was simple as lining up a cylinder to the place on the object where I want the hole and then I would create swift loops to aligh verts to each of the points on the cylinder which I would then cut out in the object.
The final piece I worked on was the lever. This piece would sit on top of the fuse which would hold in the pin. This model was quick and simple to model and the first stage was tracing the shape over an image. I started with the side view to ensure I get the curve of the model right. I then moved onto the front view which I then resized based on the width of the lever. The top got wider so I resized the points to ensure it was correct to the image. The final stage was to focus on creating the hole for the pin to be able to go through through the lever and then through the fuse as shown in the previous piece. This was done in the same process as the one for the fuse which was by using a cylinder and aligning into place and then it was a matter of adding swift loops and aligning points up to allow me to remove the faces to create the hole in the object.
The final piece of the model was the pin which I hadn't Modelled. The reason for this was due to the fact that I had already had a similar model I created some time ago which had a use of a pin. So I decided to save myself some time and take the pin piece and add it to this model. With that in place I had modelled everything and it was time to UV unwrap the model.
UV unwrapping the grenade
Since the progression of my gun models, I am more than familiar with the UV process on my models. I understand what I need to do to ensure I get the best UV's I can. The process of cutting, unfolding and aligning has become a habit to me now, that I don't need any help with UV unwrapping simple shapes and now complex shapes. Below is the final preview of the fully UV unwrapped grenade. I have neatly laid out the UV shells on the left while the right showcases the look on the object.
Texturing the grenade
Below is the video of me texture the grenade to finish off this model. I had no problems texturing the model as I knew how to navigate the software at this point as well as understanding the process of baking and black masking which meant I could add some wear to the object such as rust and dirt. During the process of texturing the grenade, I kept looking back to the references I gathered to ensure I get the right materials and colours to make it as realistic as possible to the real model.
Flash Grenade (Throwable 2)
The second throwable that I worked on, was the flash grenade. I had many issues with this model compared to the grenade but I came across with some solutions to fix my problems. I enjoyed the modelling process of the weapon and I think it turned out better than I expected as it was a complicated shape to model. I really enjoyed texturing the throwable as this is the stage of the model that brings everything together and slowly reveals the final look of the model. I had some issues in every stage of this weapon which I will discuss below which were mainly in the modelling stage but some issues were shown in my UV's too.
How did it go?
To sum up these two models as a whole, I am happy with how they both turned out. I am especially impressed with my grenade model as this didn't cause me any problems at any point of the process. I successfully modelled it, successfully UV unwrapped it and successfully textured it. I had no problems and I didn't require any help. Another thing to point out that I want to mention with all my models, is that I did a really good job at look back at my mood boards I created on Miro. This has been a great habit that I got into when modelling all the weapons and it was definitely something that paid off in the end.
The flash grenade turned out fantastic and I am really happy with the whole shape as the original idea was not so successful. I had originally planned to model the cylindrical basic flash grenade with no holes but I thought it looked a bit too simple and had nothing to it. I am glad I made the choice to switch to the new look as much as that was a pain to model as I made it work and I got the job done. There was one or two things that I didn't like about the new model that I wish I had done differently but the texturing was a great success and the model turned out fantastic in the end.
Any Problems?
As I said before, I didn't really come across any problems with my grenade as it was just smooth sailing. There was something that did stand out to me that I did wish I changed and that would be the UV's. Not all of the UV's, as the shell of the model was perfectly unwrapped, but mainly the lever. This was poorly attempted and something I wish I had changed as it would help me get in a better habit of creating my UV's in a neat way. The front and back of the model had not been cut separately to create their own UV shell but in fact it was as one piece. This was not clean and tidy and something that I wish I had noticed when doing so. It didn't look great on the final UV map as it was the tallest piece their which took up too much space on the map.
The flash grenade was a great success but had caused me a few problems when creating the model. The original model of the flash grenade was not great and it looked boring as there wasn't any real shape to the model. This cylindrical model had issues of looking good towards the top as it just looked like I slapped the lever on top of the cylinder and called it finished. Moving onto the second problem, I had issues trying to figure out how to attach the top and bottom bases to the center piece. I couldn't quite figure out what to do with this part and I tried different ways of making it look good but I was struggling as the base would look to big and the middle cylinder would look too short and it just wouldn't size up together.
The final issue I had was modelling the inside part of my grenade, which would be the fuse cartridge. I think my method wasn't a bad idea and it did turn out great at the end but I just wish I made it differently. Although it did look good, I do believe it was not the best method to modelling it. The connection point on the inside was a poor effort and I could've gone around that problem in a better way.
Solutions..?
I came across so many problems but I had ways to fixing them and the first one was the UV's. I said this before, it was not great and I didn't put any effort in to making it look good but also cut it properly. I left a poorly cut shell that led to taking up too much space and I would solve this by separating that tall shell and aligning it up a neat format to allow for more space in the UV map.
The second issue I ran into was finding the right model of the flash grenade. I originally went with a cylindrical look with no holes or shape to it which I decided was not a good idea and wanted to switch things up which is why I went for the more complex model which turned out to be a success.
I did come across a problem with the new flash grenade model and that was scaling things to fit together. The issue struck, when I was trying to connect the two bases together with the middle cylindrical shape. I attempted to initially create the two bases and have them moved and aligned with the center piece of the model which was a good idea but they looked too big. I then decided to resize the bases up to fit the size of the middle piece but then the middle piece would look too short. I then decided to try and extrude out from each side of the middle shell and have the bases attached but I had problems with the topology getting in the way and not allowing the base to have them straight cut faces on each side. I then thought of the idea to go back to having the bases separately and make the middle piece taller and have the holes larger which then paid off as it was just the right size.
The final problem that I came across was the fuse cartridge for the flash grenade. At the time of modelling this part, I didn't see a problem but afterwards, I did notice that I did a poor attempt of connecting the inside up together. I initially extruded down from the hole at the top of the grenade and then merged points up on the inside to fill in the top and bottom of the inside. I didn't like this as it kind of looked messy so what I would have done differently, would've been to model the fuse cartridge separately and not have to connect up the inside by merging points together and what I would have rather done would be to bridge up the bottom of the inside of the shell to create a more neat look.
