Title: Rocky River revisited
Post by: Hetzen on June 17, 2015, 10:20:28 AM
Here's the animation of the still I posted in images.

It was a little side project I worked on with one of our juniors who worked on the damsel fly.

..ok... I can admit now... I'm just a noob with some dreams but THAT  ANIMATION  IS  GREAT!

That's fantastic!! That dragon fly looks awesome. Is it rendered in TG or comped in? If so, great work! If it's rendered in TG, did you animate the wings in TG or is it an animated obj sequence?

Looks really great. I am curious about what Hannes asked too.

Thanks  :)

The fly was modelled and rendered in Max with an HDR exported from TG and comped in After Effects.

There's some interesting workflow problems that weren't solved to the level I'd want. Camera in and out was an issue with unit conversions and the distance the scene is to the origin in TG.

Cheers

Damn that looks nice! Post it on YouTube or Vimeo so we can share it with the world. :D

Thanks Oshyan.

I want to fix a few things first in post. The flickering rock on the left. The end abdominal segment shadow. Some time stretching on the launch. Improve the focus pull at the beginning. And a few other things I didn't get a chance to finish.

When you finish, please do post an update. This is awesome work. :)

That's beautiful. Hard to focus on issues as it is just awesome.

Unbelievable good work!

I like especially the part when the steps of image developement are shown. Great!

I like it. The screen wipes about 30 seconds in, are they different Terragen iterations or were they something else? Thanks.

They are builds on post processing. Exposure, colour correction, vignette to shift composition focus, lens flare, depth of field blur using TG z-depth pass, motion blur and chromatic aberration (how red and blue shift on a camera sensor through a lens), final curves and saturation. All external tweeks to TG.

It's kind of like processing a photograph negative towards a 'look'. Or how some of these Instagram presets work.

Basically an artistic kind of way to show how the scene was build :)

Awesome Hetzen,

Great piece of art work.
About the water... mind to share the animation process and values?
I tried to animate water on Terragen once but nothing came out of it....  :P

Cheers

Great work, thanks for sharing and for showing what is possible.

Hello Ben

For the water, I didn't use the water shader, just a reflective shader, as I didn't need the transparency in this scene. This cuts down on render times.

I created a lake object, then plugged in a surface shader into this. I then created the subtle ripple displacement I wanted with a PF plugged into the displacement input on the surface shader.

To animate it, I used a Get Frame number shader then multiplied that with a vector. I use the vector to determine the direction I want the frame number to push the PF, so a vector of (-1,0,-1) on a compass would be South West. This is then plugged into a Vector Displacement shader, which is then plugged into a Transform Input shader. Then unplug the PF and connect it to this Transform, the output plugged back into the Surface Shader. As the frame progresses, the PF will be pushed 1m per frame, which will be way too fast. So open up the dialogue box of the Vector Displacement and put in a decimal value in the Final Multiplier. I figured that the water would be moving 10cm or 0.1m per second. I was using 25 frames per second, so divided 0.1m by 25 to find out how far the water moves per frame, so the decimal value I put into the Final Multiplier was 0.004.

To get the ripple to 'evolve' I went back to the PF and switched on 4D noise and played around with the setting until it looked natural. This is a good time to render some test frames to see if the movement is what you are looking for. So it's a good idea to switch everything off that will contribute to render time.

Once I got that, I plugged in a reflective shader into the Child input on the Surface shader. Done.

You could skip the Get frame process and animate a Transform shader, but for me this adds more work in getting things to move right. As TG will ramp the in and out of those key frames by default (the ripples will speed up and slow down) and working out where the PF should be in x,y,z is kind of a pain, especially if you want to extend the animation. I just have two things to set, the direction vector and the speed multiplier in the Vector Displacement shader. I use a similar setup to move clouds.

"As TG will ramp the in and out of those key frames by default (the ripples will speed up and slow down) and working out where the PF should be in x,y,z is kind of a pain..."

Just go to the animation tab and switch the mode from TCB to linear

Yeah I understand that, just thought I'd point it out.  ;)
