cryengine film tools

R&D for the Raining Fire movie project rendered with cryengine :

Render with alpha channel for further compositing

Camera sync in-out with 3ds max or maya

Export passes (render elements) and z-depth

Area shadows (like raytraced shadows not soft shadows)

Blurry reflections

Dual stereo camera option

Depth of field with multiple solutions including an accurate one that works even with glass

Raytrace quality motion blur (higher than any real-time engine at the time of this writing)

Adjustable vignette
Human characters solution
SSAO - higher quality (comparison and tests soon)

Voxel modeling and painting

Dynamic effects for plants and other objects
Anti-aliasing

Since all my cryengine research, tools and shaders are scattered around I decided to gather some of them here in this blog.
Threads about my movie on crymod and cgsociety.

Dirt Shader procedural

2011-10-09T00:57:00.000-07:00

I don't have time anymore to develop this, but since I had a few request, I will post this here.

Download links (on crydev)

DX9 - 7 presets included

DX9 - for rendering with alpha channel - pictures

DX10 - 2 presets only and 7 sliders missing

The included presets

rust

chipped paint layer

+ static layer

dirt-dark-general layer

no dirt shader

weird scratched paint layer

downloadable moss presets (simple text documents) - details here

no shader

moss preset

moss preset - gif animation on-off

the shader can be used also for an increased snow and ice effect

You can even add two different layers on top, because the shader is using the Crysis static and dynamic ice

or using the internal Crysis "bubble" layers for an interesting look. And the thickness of the "glass" or ice can be adjusted

A requested blood effect made in 5 minutes. Since the effect is procedural you can see how the quality can be higher than regular textures

Other uses. Some kind of strange noise, which can be animated as you can see in the youtube video

I made some animated pictures for a few sliders to show their effect. The lag is from the animated gifs, in editor is fast and smooth.

With this shader you can add procedural dirt. By adjusting the sliders you will get fast real-time feedback so it's very easy to adjust and create all sorts of looks as you can see in the pictures.
The shaders were made (based on Crysis original shaders) on a Nvidia GTX 8800 so I'm not sure how well it works on Ati cards.

All the pictures were made with DX9. You can run DX9 on windows 7 also.
By taking out a few sliders (more info here) I managed to make a different version compatible with DX10. However it seems to have more problems than the DX9, probably because I only worked on it for a few hours.

If you adjust the sliders for a certain amount of minutes, the object will disappear. This bug is not from my dirt shader, the crysis default shaders (the complex ones) have the same problem. The only solution is : save, close the editor and run again.
You won't see this bug after you're done tweaking the shader.

A quick explanation here how to create your own sliders.

motion blur

2011-05-19T21:02:00.000-07:00

For many types of movie shots, the default motion blur included with cryengine, is enough. But many sequences require a higher quality 3d motion blur. For example rotating objects, or blades of grass or leafs passing rapidly in front of the camera. Without a 3d motion blur these would look bad.

Or imagine a tornado made with high speed particles. I will upload a 3d motion blurred cryengine tornado movie in the future.

These insects look bad without 3d motion blur.

More proof (low quality for now)

animated gif :

Panning the camera behind close objects like foliage or railing or other objects would look bad without a 3d motion blur.

This type of filming usually occur in most movies at some point and if you don't have a raytrace motion blur you will get the artifacts shown in this comparison.

area shadows

2011-05-19T21:01:00.000-07:00

Adjustable Area Shadows (viewport low-res pictures). Correct overlapping shadows - something which is not possible with actual algorithms like Nvidia PCSS.

more pictures and movies soon

default crysis shadows

another test with overlapping

larger area shadows. Notice how the teapot handle cast sharp shadow - how it's supposed to. Objects should cast sharp shadows on closer objects and soft or very soft on farther surfaces

some older tests

anti-aliasing

2011-05-05T07:02:00.000-07:00

I made this post because someone was concerned you can't get production quality antialiasing, let's say - with a quality comparable to a Mental Ray render.

with some adjustments

if needed the antialiasing can be increased further

In fact I can choose between two or three different solutions for AA. And I can even combine them. And if you search crymod.com you can find there other real-time solutions as well.

(when I will finish my current film, I will post again this frame extracted from movie. It will have even better AA)

DOF

2011-05-05T05:35:00.000-07:00

Depth of field obtained with z-depth can lead to very high quality dof

Or you can use the real-time solution I posted here

You can even use different shapes as you can see bellow.

Since it's real-time the quality can decrease depending on how big the bokeh is. But with certain careful chosen values (and small bokeh), the quality can be as good as a post process filter.

________________________________________________________

The following solution is a work-in-progress attempt to eliminate the limitations of current dof solutions.

Even with renderers of programs like Maya or 3ds max you have the same kind of limitations when it comes to transparent objects like glass or water or near de-focused objects. The solution would be a true raytraced DOF. But that has a huge disatvantage : a very long render time per frame. That's why when it comes to rendering movies, most will turn to a z-depth post process solution.

The following cryengine renders show a working depth of field even with transparent objects, similar to a raytraced solution. The render time is high, but they are still much faster then ... for example - a Mental Ray render.

near de-focused objects and glass

render with alpha channel

2011-04-19T11:41:00.000-07:00

You can use my workflow with the shader posted on Crymod to render models with alpha channel.

The palm is a regular palm from Crysis, rendered with alpha channel and composited in this real photo. The shadows were also rendered in a separate shadow pass and composited.
