How the elements were put together<br />

5 hours<br />

render time<br />

Resolution:<br />

2,500 x 1,406<br />

Here I deployed another one of my favourite elements – cloud shadows. They<br />

04 strengthen the spacial impact and – if placed correctly – help to create a focal<br />

point for the eye. Volumetric lighting was turned on so that the Spectral 2 clouds cast some<br />

nice shadows throughout the atmosphere.<br />

After various tries with procedurally placed<br />

05 EcoSystems, I decided to paint them by hand.<br />

Consisting of Vue’s Plum Tree and two other kinds of small<br />

shrubs, I painted an ecosystem to emphasise the weird<br />

topography of the crater/vortex. Here you can see my very<br />

simple setup and the final painted ecosystem.<br />

I usually like to ‘underexpose’ a bit so no p<strong>art</strong> of<br />

06 my render gets overexposed. I rendered this with<br />

Ambient Occlusion with the simple ‘final’ settings. Not very<br />

spectacular, but I personally like to do a lot of tweaking in<br />

Photoshop as I find that method much quicker.<br />

A great thing about Vue is that it can render a layered Photoshop file, containing<br />

07 useful passes and Alpha channels. This image shows the different layers I used to<br />

‘mix down’ a version of the render for me to paint on. Left to right show: Diffuse, Shadow,<br />

Reflection, Indirect Lighting and Atmosphere Gain channels activated step by step.<br />

A lot of things happened<br />

08 once I took the image into<br />

Photoshop. First, I flipped the whole<br />

render to make the composition<br />

more readable. I replaced the water<br />

with a photo I took and cranked up<br />

the spec of the water surface to<br />

boost realism. The background was<br />

cleaned up and trees cloned to break<br />

it up. Quite severe colour corrections<br />

and some painted-in atmosphere<br />

tweaks finished this step.<br />
