Project Summary - Evaluation

I have learnt a lot from this project and year as a whole. I initially started the year eager to help out as many groups as I could but quickly learnt I was underestimating how much work would be involved and had to make some tough choices as to who I could and could not help. This was a major lesson I learnt, so I have always started thinking before rushing in and promising to do work which I would underestimate in terms of time scale. I learnt it is better to promise less and over deliver, than to promise lots and under deliver.

I quickly became a member of Andy's group 'The Deep' and also signed on with Kofi's project 'Heroes 1.0'. For Andy I agreed to model and texture characters, as well as do some lighting, animation and whatever would be needed. For Kofi I agreed to model his character (model/uv map/texture) and also help out where I could in terms of modelling, uv mapping etc. I also made my services available to other groups, letting them know I could UV map if possible.
I did all the work that was asked of me to a good standard and tried to always deliver as fast as possible. Being efficient and quick was a priority of mine.

It got hard to balance things at one stage, with the dissertation and IPP as well as everything we had to do for the films, but the scheduling we did and developed during Jared's unit came in very handy and allowed me to work on certain things during certain days. The stuff I learnt during Dan's unit at the beginning of the year has also helped me greatly and got me started on my journey to become a good rigger, it was just the right unit at just the right time. It allowed me to learn something new and push myself to become better. It was and probably still is the best thing I did all year. Even though my rigs were not amazing I learnt lots and got my skills up to a decent level for me to build off in my own time.

Working with groups has been quite fun and interesting, especially for such a long time. There were times I wished I had more control but quickly realised it was not my vision and just had to do the best I could to bring the director's vision to life.

The communication has been great this year, the group which is quite big has always been able to stay in touch and I have always kept people updated on my progress via our facebook group or my blog.

My strengths have been my speed, efficiency and willingness to learn and constantly better myself. I never settle with what I have now, im always pushing myself to reach a higher standard and I have definitely wanted to impress my group members and fellow workers.

My weaknesses have been scheduling and artist blocks. The scheduling took me a while to develop and even when I did sort out a timetable I still sometimes felt a bit overwhelmed. I also had art blocks which would prevent me working to the best of my ability but I found the best way to get through them is to surround myself with people and gather inspiration from my fellow peers. It helped a lot to see the great stuff that was being done and eventually pushed me to work harder. I guess I just need that creative energy around me to allow me to push myself.

It has been great working with everyone this year, and I cannot wait to get into the industry.

Shot 25 Final Lighting

For the final lighting, I actually decided to use a part of the light rig that Keith made and used for the other scenes. This is mainly because I wanted to keep continuity between the lighting in the various scenes. So I imported his light rig, deleted one of the directional lights, and added a new spot light to bring out the eel and child. I think it works well like this creating a dark mysterious look.

Shot 25 Lighting Development

Here is my step by step show process for the lighting of scene 25. Keith asked me to light the scene so it could be rendered later during the day. Time was of the essence so it had to be done quite soon. Here I went with the idea of less is more, so I only create as many lights as were necessary, 2 directional lights for some simple lighting of the cave and 2 spot lights for the light coming down the tunnel which is whats illuminating the eel and child. I showed Keith my inital tests, and he said they were just too bright and after going through some other scenes and renders, I understood if had to be much darker and more atmospheric. I then deleted 1 of the directional lights and dropped the intensity down on the spot lights. I had shadows being cast from one of the spot lights, using ray traced shadows. I think the lighting is decent, and a lot of tweaking will be done in post so all that is needed is a good base which I think im close too having.

Shot 16_Eel glow spheres added

Some shots of the orbs being added to the mesh of the eel in Shot 16. I was asked to do this by Keith as he desperately needed to get onto lighting and rendering the scene. As mentioned before it was a case of importing the orbs into the scene, then manually placing them all and finally using the wrap deformer, making sure to select the orb first and then the mesh.

Quick Render Test_Shot_25

This is just a quick and very rough render test to make sure everything in shot 25 was working after I had cleaned the scene, clearing a lot of junk out of the outliner and cleaning the hypershade out. As you can see the orbs work very well, giving a nice diffused glow and all the textures are working perfectly. The next stage for this scene is for it to be lit then rendered.

Glowing spheres on Eel - Shot 25

Whilst cleaning up shot 25 to be used as a master scene, I linked all the textures for the eel and then noticed that the glowing orbs were not connected to the rig, nor were they even in the scene. I got quite concerned so they are a big part of how the viewer is going to identify the eel, and mentioned this to Andy. We then called Clym and asked if he had attached those orbs to the mesh, and he said he had not. It was then a case of how to rectify this, and he suggested using the wrap deformer, to attach the orbs to the main body, as they would then follow the mesh.

So what has to be done for all shots including the eel is to manually import the orbs, and then connect them to the existing mesh using the wrap deformer. It is an easy fix, however quite tedious, as I began with shot 25. I had to go in and manually move each orb to the mesh, then attach. Its going to be worth it in the end :)

Eel Glow Intensity and Colour change animated test

Andy asked me if I could test out the eel's glowing orbs to make sure they could be controlled appropriately for the animation. I then quickly made this test in maya, testing the intensity as well as the colour change. (Andy wants the orbs to change colour as the eel changes moods). I simply said its a case of key framing the flow and diffuse colour attributes in the attribute editor, which is straightforward. I carried out this test, showed it to him and he was glad it all works fine.

Shot 25 Clean up and Master scene creation

I was given the assets for shot 25 Andy, who asked me if I could clear up the scene, clear the the outliner, and re link all of the textures so that it would be good to go for lighting/rendering. When organising the scene and trying to link textures, I noticed the hypershade was extremely cluttered with nodes that had been imported with the various models. This happens when everyone has various different scenes with animation/rigs and they all create individual textures but then forget to clear the scenes before exporting out. So this has resulted in a massive amount of unused and irrelevant nodes/shader networks. I solved this by deleting all unused nodes under the edit menu in the hypershade, as well as manually going in and selecting specific nodes. After I was done, only the relevant shaders remained, and I also suggested that perhaps the scene could now be rendered on the render farm.

I asked Keith to give it a shot, and he got back to me saying the test frames he sent to the farm came back fine and it worked well. It shows that having the right scene with only the necessary nodes is how to go about using the renderfarm. Anything excess or unused is going to cause the render to fail.

I also told Andy that this scene should perhaps become the master for the ice cave, seeing as it is already clean and ready to go. He agreed and Keith has now started using this as the base for his lighting.

Artefacts when rendering

After doing some test renders of the environment using my newly created lighting I started getting this problem of artefacting throughout the image. I could not figure out why, and I began testing out the render settings, shadow samples but that did not prove any success. I then inspected the outliner and it was extremely cluttered and I began noticing duplicates of objects and then went into the viewport, switched to wireframe mode and began moving pieces around. The conclusion...there were duplicates of everyting in the scene aside from the kid, this happened because I Ben forgot to delete the entire environment when giving me the animation. So when I brought the animated kid into the lit environment, all objects were there twice. So I then had to go in and delete all the irrelevant meshes.

Interior Lighting More development, step by step

Here are some more step by steps shots and the finalised lighting. I tried using final gather but as soon as its added, the render times increase so that was not an option. I went through many little tweaks to make sure the lighting was just right, with enough bounce and I also ended up creating a light for the water to get some of that blue creeping in through the windows. All in all I think its decent, I showed it to Andy and he was happy. I created a dimly lit setting whereby the light is designed to keep the eyes focused on the child in his chair.
