Feedback from C4D Café forum

After my last post I revisited the site to see if anyone had left feedback from the two videos I posted and these were the results:

Although there were not loads of responses it is good to get at least a few which directly relate to the questions I asked. It shows that people on the forums have more to say than if you just use a simple Survey monkey style questionnaire as this gives a lot more room for explanations tips and tricks.

This basically supported my suspicion that there is almost no need for a GI element as the light boxes (light dome) have done a good job lighting the scene efficiently. It is also apparent that the shadows may be the reason that the realistic feel is not complete. This can be seen in the latest control box update with the shadowing ending up looking like two different materials have been used. This will need to be edited and now that I have some suggestions on how to do that I feel a lot more confident doing so.

There is mention of trying out an HDRI for reflections however I really haven’t the need for much reflection and therefore don’t think i will use this technique. Also studio HDRI was mentioned however this is a very costly setup and considering I can get a pretty similar effect without having to fork out for a professional lighting kit this is not an option i can implement. Although for my re renders i will try adding some slight bevelling to help with reflections. However I feel that using GI on top of this process will just push the render time through the roof and therefore will be pretty ineffective in the time we have left to complete the project.

It was also mentioned by an esteemed colleague that the computer used within the control box videos would be made more visually effective if screenshots of the software were added to show that there is a reason for them being there e.t.c so this will also be added in to hopefully boost all aspects of the animations.

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…

 

Pre-Installation Video – Concepts and Storyboards

The pre-installation video will be a mixture of all the different practices – Graphics, 3D and video. This will involve shots of the physical machine (Hardware) and also shots of the software and how to install, system requirements (NO MAC OR LINUX).

Parts of the hardware will be made in 3D as it will be easier to film harder to reach areas in virtual reality space. It also means that parts can be pulled apart and deconstructed without damaging any real equipment. It also eliminates the majority of the language barrier issues and problems.

It would also be really quick and easy to animate a usb being inserted into a port showing the key stage of the pre installation. Then we could show the install process on a 3d computer with key points marked out and brief text talking about what to do to install.

Then cut to the machine working real footage and a brief message to say once its installed watch the training video.
