Rendering 0.2 - Basic Lighting Setup

After doing some research and tutorials it was time to actually start doing some work on my assignment scene. It took a little while to get to where I am now, but I have almost clear understanding how it all works, at least about final gathering, global illumination and shaders. I really like how little things can affect the whole scene and the colours, its pretty cool.

Global illumination was fairly straight forward, nothing crazy about it once I figured out number of photones and all that. After playing around I eventually settled for this:

Render time: 0:19
Objects: Floor and walls
Lights: 1
Photones Intensity: 3,000,000
Gloal Photones: 50,000
Radius: 15

My first problem first Final Gathering was that it was making the scene way too dark for some reason. After looking around for solution I began to change the photon colour bounced from the floor and walls to something much lighter, which helped to brighten the scene. Also adjusting accuracy of final gather and using Radius Quality Control helped. Not sure if its best practice but so far I am setting the RQC max to 10% of the scene size units and min to 1% of it, so in my case it was 46 and 4.6, the scene or at least the main room is around 460 units. Below are some results of trying around different settings and position for the photon emitter light.

At the last picture I do like the "sun" reflection in the window, which I might revisit later, but there will be big ass tree in front of the windows so shouldn't worry about them too much. I have also took down diffuse of the windows frame for photons which made them much less shiny. I might turn it off or make it bit more less later but as I said, they wont be probably visible with all the objects. This is the final image for today:

Render time: 2:18
Objects: Floor and walls
Lights: 1
Photones Intensity: 4,000,000
Gloal Photones: 50,000
Radius: 15
Final Gather accuracy: 250
Radius Quality Control: Max 46, Min 4.6

And for the end, I changed the wall material a little and used spheres for my tests. In the scene there is no bump for the walls yet, not sure I need one. I am happiest about the wood material so far, I really like how it looks in the scene, especially on the floor. I like the marble too so far but will see how it will look in the scene itself.

Technical Animation 0.2 - Burn Baby Burn

More fire stuff! This time we were doing particles system in Mata, more specifically nParticles and fluid smoke. Which is actually quite fun, just need to play with the smoke more to figure out how to optimize it so its faster to cache and then render, it was taking bloody ages and then it also stopped simulating towards the end, the smoke just stopped while the particles kept moving, not quite sure what went wrong there.

Rendering 0.1 - Texture Test

So in this module we are learning how to make photo-realistic renders, sort of, its mostly about how to set up lightning and how it all affects the scene, which I find very interesting. Not sure I wanna do it as career, but the things you can do with lights is pretty cool. Anyway, as my project I am doing Xmas scene. I want to make three renders, or attempt to. First with day light, one during night and one where three is on fire with a shadow of a little girl in the floor coming from doorway.

I started with the colour scheme and thinking about textures. Thanks to MEL scripting I have learned to work with something I personally enjoy, as in colours and theme so I went with purple-brown, mainly, also black, yellow and white to break the colours.

My inspiration:

 

 Test textures; black metal, purple wrapping paper, purple wall, brown wood floor, white marble. I am considering adding basic colour textures to the scene itself to see how colours will go together, but I think I have pretty good idea. Soon I have to start setting up lights, by end of the week I want list of texture tests and lit up scene.

 

VFX 0.2 - Let it burn

Started doing texturing for the fire extinguisher, it is really detailed so there is few texture maps for it. I went 1k square for the textures, should be big enough for HD, the camera is close to it but not extreme close ups. Making the colour maps took big longer than expected, but I am happy with them so far, next I gotta do bump and specular maps. Probably will play with the colours bit more too. By end of the week I want to have all 4 objects textures. The others wont take as long because they are in distance and quite simple, where the extinguisher has lots of details. I think I spent the most of making the instructions on it, it was images at front and both sides. Since I want it to look realistic I took time to get it more or less like it is in real life for CO2 extinguishes.My work so far (only colour maps):

VFX 0.1 - First Test

The lack of posts it due to not having much practical work as before. As much as I work on project its mostly research so far but I will be starting to update more often again as I will be starting doing actual work can show, starting with Visual Effects.

First I wanna say I really like Nuke, its like PhotoShop but for movies, which is awesome. It even works better than PhotoShop in my opinion. In the course we are learning how to use Nuke and NukeX for tracking and composting, which I really like as well. Tracking is so much better with Nuke, I love it.


For my project I have to texture 4 object and then places them into a live action scene so it looks realistic, its exactly what I'd like to eventually do as a job. Today I just did a test of exporting Nuke 3D scene, importing it to Maya and adding an object into it, its not perfect but I think it shows it can be done.


So over the next few weeks I need to, texture all the objects, track the scenes (or use already tracked ones) and composite them. I will be starting with the texturing so I have the models ready and need to figure out if it will make difference if I track myself, if not I will track just one scene so I can add it to the show-reel.


Here the video I have made today. The scene is actually something I will make look much better for final assignment.
