Space Pug - Black Hole Experiments 5

Blue Black Hole from Max Ashby on Vimeo.
Purple Black Hole from Max Ashby on Vimeo.

In the void of space lurk enigmatic black holes with different colours according to each black hole's personality. Actually, this is another black hole experiment that has worked out very well. The black hole consists of a simple cone with a fully dark Lambert shader and the large, colourful disks around the hole are particles that have a texture attached to them. This was all possible thanks to this useful tutorial:
The purple galaxy is just an image from Google, having a centralised white source was important. I also created a copy of this image and using Photoshop created a gradient map version that simulated height and depth in the particles. These particles were emitted from a flat, cylindrical plane and it is important to set out the UVs correctly before attaching particle emitters. The twirling was created using an emitter.

This blue galaxy was made entirerly in photoshop and was meant to mimick the purple galaxy design.

Rendering out this work required both Mental ray and the Hardware renderers and thus required some learning about render layers. I still need to work out Maya's Extension 2 render layers so I used the legacy settings and this quick tutorial for the render layers with Maya:

The "warping" effect behind the black holes was a simple starry background from Google that was placed into After Effects and utilised a "warp" effect nod, pretty cheap and nasty, it needs some refining.The glow from the particles was also done in After Effects, which also needs work.

This is a big improvement over my earlier experiments and I am very pleased with the results, making these did not take longand that's good becuase it still needs some tweaking but overall it looks much more closer to what I had envisioned originally.
