Anatomy of one of my renders

So here’s a quick breakdown of one of my renders using my current system. I’ll give some system specs at the end.

I do all my 3D work in Lightwave 3D. I started using this on my Amiga back in the early 1990s. Then when I worked in the film & video industry it became my favourite piece of software. I’ve tried the other ones out there but I’ve always come back to Lightwave 3D. I guess it’s better to know a lot about one program instead of little bits here and there about others. Here is what the scene setup looks like.

(click image to open it in a new tab)

LW_image_1As you can see there are 63 objects in the scene. Even though you can only see the console room in this image the library and the lab are also loaded into this scene. There are 5,724,189 polygons loaded. I use instancing a lot to keep memory overhead down and I don’t think that the polygons of those objects is included in the total. The object memory takes up a little over 2 gigs of ram. Almost 2100 surfaces!! and finally 294 images for those surfaces. To me the most interesting thing is that there is only 1 light in the scene. In Lightwave 3D you have to have at least the one default light. I’ve used this light as the sun shining in through the giant library window. I commonly use the rule of thirds or golden spiral when laying out my scenes. In this case I didn’t because it’s setup for a 360 panorama render from various locations around the room.

For rendering I switched over to the octane 3D render engine from the default Lightwave 3D one. In it’s current version right now octane is 100% GPU based. So while I’m rendering my CPU is not bogged down in the slightest! This is amazing really as I’ll be streaming music, watching videos and browsing all while my machine plugs away on the image. But sadly it also means all the money I spent on putting my system together is rather wasted. Oh well it’s the final results that matter I guess and I put my machine to work in other areas as well. Anyways for this particular image I had the machine render away for 6 hours. The longer you let it render the less noisy the final image. But there’s always noise sadly.

Final untouched render (for those technically interested I used Octanes PMC render kernal with 32samples, Diffuse Depth of 8 bounces and Glossy Depth of 12 bounces)IPR_image5_2

I also render out various passes to help me in photoshop with the final image.

Here’s the ambient occlusion image with an occlusion distance set to 1 meter.IPR_image5_AO1

As well as a Z-depth mapIPR_image5_z

And finally the Texture ID image. I  use this to help with the selection and masking process in Photoshop. One of the problems with the Ambient Occlusion image is that it really darkens the roundles which are supposed to be giving off light. Being able to quickly select the surface ID and remove that part of the image saves me a lot of time with hand erasing the parts that are causing problems. The texture ID image is also known as the Clown Pass for obvious reasons.IPR_image5_MID_1

OK. So thats most of the images I use. The only other ones I really use are Ambient Occlusion ones where I set the occlusion length to different lengths (from .5 meters to 5 meters).

Then in Adobe Photoshop I’ll take the base image and de-noise it using a few plug-ins like Topaz Labs De-Noise 5. I’ll adjust the levels/saturation and maybe play around with the Color Lookup Adjustment Layers. Once I am happy with that I’ll add the Ambient Occlusion image as 2 different layers. One set to Multiply and a low value (10-25%) and the next layer as Color Burn (again 10-25%). Daniel Reed and I spent a lot of time working on figuring out the best ways to use the AO (Ambient Occlusion) layers to our liking. I’m not sure if it’s the correct way? But it works for my stuff at least.

Then I’ll use the texture ID image to select the areas that are emitting light and delete them from the AO layers. I’ll add in fake lighting elements like light beams through smoke or extra bloom around light sources. I’ll also add or remove light bleeding or colorize areas that are not to my liking. In this case the blue light bleeding onto the spider-web glass floor and the orange glow of the under-room. Then adjust the levels so the top part of the console room is not overly dark (but not overly bright either)

Finally I’ll overly the z-depth image and play around with the layering and opacity. It can either bring out detail and lighting in the back of the scene or make it darker. I like to make it a little lighter and simulate the effect when you look through the air at distant sights and they fade the further away they are because of light scattering.

And the final image..IPR_image5_1


So this is pretty much my process. There are a few other little tricks that I might do if I’m feeling so inclined. I’ll keep those one secret 😉

Finally I said I’d give you my machine specs. I’ll give you all the details as they are pretty impressive I think and I do love to boast about them 🙂

Um.. yeah. That’s about it.

Doctor Disco

I have not been in the best of moods for modelling in long while. So over the past few weeks since Series 9 started I’ve been getting back into it. Here is one of the things I’ve been working on (well technically two things. But they go together)

guitar_1It’s the Doctors Yamaha SGV-800 electric guitar. This was rather a fun thing to model as it’s not something I’d normally attempt. The curves on the body were quite fun (and painful) to work out. The textures of the opal faceplate change as the angle of the camera moves. This was a tricky surface to create.

guitar2_1In the building of this model I used the PDF manuals for the guitar as well as over 80 reference photos of the whole SGV range of guitars.


The final image shows the Doctors amp. It’s was based on a Fender Mustang 1 portable amplifier. Of course all labels were taken off and replaced with the ever present Magpie Electricals logo. For a guy who ran a tiny radio/television shop in the 1950s he really became a huge mega-corporation. I’m amazed that International Electromatics allowed them to grow so large without a hostile takeover. And by hostile I mean cybermen deleting the competition.

Entry way

So I’ve decided to use the blog portion of this website for more ‘small but timely’ updates. To show the small things I am working on. Mostly Doctor Who related renderings. But I might squeak in other content if I consider it cool enough.

Anyways my console room re-design is never finished! I am always playing around with it. If I find something that I like I try to include it somewhere. Today I re-did the main doorway. I’ve included the glowing outline for the police box doors as they first showed up in season 9. I still include the metal frame of the earlier doorways because why not.

The change I am on the fence with is the inclusion of the Gallifreyan writing on the sides of the main doors. I am sure that they’ll grow on me over time.



Finally launched it!!

Sigh. Well over 2 years later I finally got off my ass and finished the migration from the old website to the new one. Thats ONE less thing in my life to hang over my head. Now onto the other 10^21 ones.

New Website!!

Many people have contacted me over the past two years (since my last update) to see if I’m still alive and/or still producing Doctor Who related images. The answers is YES!! I’ve not posted any images for ages because of 3 simples reasons. They are

  1. I’ve been rather depressed/angry with finding my images being used in commercial items without my permission. If you look at most of the TARDIS iPhone case covers out there they are infact using my image of the TARDIS. They just stole it without permission and violated the copyrights and copylefts of everyone.
  2. Even though I wrote the old gallery system from scratch myself it was a pain to update and add new images
  3. I was rather too lazy or too busy working on other things.

Hopefully now that I’ve switched over to a real CMS (content management system) this will enable me to update more often and I have some other ideas for the sites future.
