Advanced Lighting Techniques in Cinema 4D

Lighting has a very important role to play in all things but especially in 3D as it is a lot harder to effectively use lighting in a realistic way using the standard light settings. Therefore it has become important for me to progress as an animator to incorporate more professional use of lighting by using the inbuilt lights in C4D.

This tutorial has been very useful in pointing out the fact that all 3D light is flat and does not react in the same way naturally occurring light does. Instead of bouncing off surfaces and bending the 3D light carries in one continuous line. Therefore some extra measures have to be taken to create a visually rich and high contrast images.

The introduction to 3 point lighting is also a game changer and although i already had some knowledge of this lighting technique i failed to use it before in  a 3D environment. Another point well made was using more than 3 points as the lights in 3D only pick up shadow, mid tones, and highlights whereas in reality there is five main points of light shadows, quarter tones, mid tones, three quarter tones and highlights. Therfore we must add in more soft lights to create a higher dynamic range of light. This effect can be achieved by adding in different layers of light slightly off point from each other and emitting slightly softer light each time.

I could just use GI (Global Illumination) with a HDRI image however this would defeat the point of the experiments and learning about lighting is the real goal here. It is also mentioned that GI is actually a pretty lazy way of lighting and can make you’re image look flatter, however using it alongside a proper lighting rig can improve the image/animation. Therefore I still need to learn proper lighting techniques to boost the potential of my overall animations.

Adjust the default light C4D – This is a quick way to change the position of the lights within a space. This could come in very handy and i feel it will definitely speed up my process as well.

Free Light Dome – A quicker alternative to GI as these are all separate lights it will be faster and also there is a lot more control over colour schemes and shadow maps.

10 Tips for better lighting in Cinema 4D – Similar stuff to the first video, however it does mention the use of different shadow types and features. It states that “Area shadows are by far the most superior shadow type as they offer high accuracy and the most control.”. However  “area shadows are the slowest to render. To speed things up you can decrease the number of samples and accuracy, this will give you results faster but also will introduce noise.”

So a lot to think about and experiment with…

PROJECT 5 – The Final Brief

For project 5 I will be revisiting C-TEX and making a further 2 videos to complete the C-TEX Colour package. These will be available after the client has made the initial purchase of the machine and therefore will go into a lot more detail about pre installation of the machine and also training there workers to use the machine, and also showing the managers how to get the right information that they need from the spreadsheet that the program creates. Detailing different information about the materials being tested.

The first video is the sales video which was completed for Project 3.

The second video is a pre installation guide –

Pre-Install Video Script

Should be less than 5 minutes

Thanks for buying c-tex colour, this video guides you through 2 things:

1. The information we need from you in order to manufacture c-tex colour ready for you

2. For you to prepare ready for the installation

So…the information we need.

Firstly, we need a photo of where you would like c-tex colour to be installed. Here are some examples…

Then we need some dimensions so we can fit c-tex colour to your machine

Here we show you the dimensions we need

Secondly we need to know the direction the fabric is flowing in: please indicate this with an arrow

Thirdly we need to know at which side of the machine you wish the PC and Operator monitor to be located

Also please take a photo of your length measuring wheel (if you already have this installed) so we can assess how to fit our encoder onto this

Lastly, machine construction: Please indicate the materials your machine is made of and thicknesses. For example, Solid Mild Steel 6mm thick, Mild Steel Box Section 2mm thick with section of 100 or Wooden Section 15mm.

Therefore, the photo you send us will need the additional information as shown here (photo with all details on)

We can then build c-tex colour to fit your machine

Onto the second step:

For the installation we need:

Network Access to machine area for us to connect the c-tex colour PC to your network

Electrical power: single phase

If you have not purchased a control cabinet from us and you will be providing yourselves this needs to be onsite when we arrive. We require minimum internal dimensions of Height: 1000mm, Width 600mm, Depth 600mm. The operator monitor can be mounted above the control cabinet of you can purchase a control unit with monitor surround.

If you have not purchased a PC from us and you will be providing yourselves, please ensure this meets the specification we list in our agreement document and is available when we arrive onsite

If you are running c-tex colour for an inline process, for example a continuous dye range or sanforiser or compactor we will also need a mains compressed air supply provided, to include a regulator and moisture capture mechanism.

When we arrive onsite for the installation we need to meet with your factory engineering manager and IT manager to present what we are going to be doing while onsite and what support we need.

We will also need a meeting room with a projector or large monitor in order to give a training presentation for 1 hour. For the training we will need your colleagues who will be: operating c-tex colour, analysing the results of c-tex colour and managing the implementation of c-tex colour.

Adam has done these rough storyboards which really helped me to visualise what exactly needed to be done in terms of 3D animations. As this is the job role i will be fulfilling for this final project. I will of course have to make some more detailed sketches of what exactly needs to be shown in 3D and camera movements etc, however this quick visual is very handy for mapping out the whole video 2 sequence.

 

The third video is a training video – Full Script to follow…

 

Sales Video Showing Problem, Solution and benefits of the product – Conceptual and prototype ideas.

 

The Concept for this is family and friendly. Meaning to show the company in a friendly way as a laid back and relaxed environment.Image result for coloured 3d ribbons

The problem.

It will involve graphics and 3D to help show the current issue within the textile industry. Highlighting the T-Shirt with seemingly matching colours then a zoom in will reveal that they are unfortunately slightly different shades. I think using ribbons for this could look quite cool to replicate the threads of the material. Or we could use 3D blocks to replicate the colour swatches which is used in the old method of colour matching.

A few different options here:

Also i have a prototype of a logo screen being rolled out. Laid across five separate carpets. This looks really cool and i will add it into my progress post. I could also make it look a lot more professional with a proper high res image and adding some masks and effects in after affects.

The solution.

I will then show not the solution but the desired outcome and simplifying the process. This will involve showing a similar shot to the problem but now with correctly colour matched items. Also it will show a traffic light system to show the functionality of the product and although the traffic light system is in the software it will help to so how the software works without actually showing the software.

How to use.

This will mainly be filmed and i don’t think much 3D will be used as it would be more advantageous to use filming so that techniques like stop motion or maybe a time lapse of people working can be used. It will show basic installation as it really just needs to be placed on top of the rolling station. Then also a bit of the software as this is the main element of the usability. This would all look a lot more professional using real footage as it would be useful to show the customer the real product in motion to give them a feel for what they’re actually buying.

Benefits:

Show that it is cost effective and Time effective this could be very easily shown by making comparisons as a sort of motion graphic typography thing.

 

Like this but with facts about costs and timing etc. Also show shots of the employees playing pool and all the games that they have at the factory. To show the relaxed friendly environment as this is really what we want people to buy in to. As the product speaks for itself but the sales video should help to show personalty within the company.

 

C-TEX UK Marketing Campaign 3rd Project

Online Colour Matching

  • c-tex colour: has been designed to eliminate colour mismatching in garments and other sewn goods.
  • c-tex colour: monitors colour deviation of rolls throughout the length and at 3 points across the width.
  • c-tex colour: then batches together rolls with consistent colour to be ready for cutting together.

 

For Project 3 we have been tasked with marketing and advertising a specific hardware and mainly software that allows textile manufacturers to check colouring and dyeing. This is too prevent colour mismatching when sending rolls to garment manufacturers. It monitors the whole roll and 3 points across the width to ensure accuracy and consistency.

 

We have been tasked with creating 3 videos for the client and these involve:

Item 1: A sales video to introduce the problem we are addressing and our solution

Item 2: A Pre Install video so that customers can prepare for the arrival of their equipment

Item 3: A training video so that customers can start using the equipment well.

It became apparent in today’s lecture that the most useful way to use my 3D skills would be in the training videos as this would help show how it works while also using motion graphics to inform and teach the user about the equipment.

The key areas with this are:

Language – As this is an international product it needs to be transferable to any languages. There are a lot of sales overseas and agents that will sell the product to solely make money rather than to cater for the customers needs. Therefore there needs to be videos which clearly explain the product on offer and how it can benefit the user. This will also help with consistency of message and training so that there is always a way for users to train staff on the software and also make their own adjustments as and when needed.

Company Ethos – They are also a relatively new start up at only 3 years old The company and the environment within the textile / garment industry is “unprofessional” this means that it is not a suit and tie corporate affair. We have been asked to make this very clear in the videos. To understand that the company’s core values are more about getting the product out there and trying to make a difference in the industry. As well as concentrating on a few individual projects and really nurturing them and polishing them, making them as flawless and easy to use as possible without expanding and branching out into other avenues to quickly. In short they are not a get rich quick scheme and the opposite of a faceless corporation and they really want this to shine through in the videos.

I will start some research now into more instructional and 3D videos to try and understand what is being asked of me and also for some much needed inspiration. Also youtube and lynda tutorials will come in very handy for this project as i have a feeling a certain amount of 3D modelling will be needed and this is an area i struggle in. However the actual motion controls should be relatively easy to animate.
