DOCUMENTATION

Houdini Engine is required for Mesh and collisions, you can find a guide about how to install ithere.

More than

30 parameters

for each fractal blueprint, including different transformation modes that can be combined plus an insane control over the color and emission, all following the fractal shape.

9 Levels in total with 9 different formulas

, each one can be

animated

with the sequencer and tweaked to create the most mind-blowing environments or live visual performance, thanks to instance parameters you can easily tweak Fractal parameters in real-time, apply textures in different ways or input 3 color gradients directly.The performance varies based on the fractal complexity and which parameter and mode are enabled but we’ve decided to keep all parameters in case you want to render out short films without caring about the FPS.

All fractals are rendered in real-time using an RTX 2080 GPU and we recommend at least 8GB of video memory for a smooth real-time experience in most scenes.

FAQ

What GPU do I need for this?

We recommend using an RTX 2080ti or faster

I can’t see the fractal, what should I do?

Be sure that the static mesh where the material is applied has big bounds, 6000 seems a good number.

Set the clipping plane in project settings to 0.5 and restart the engine.

Set fractal material instance parameters to it’s default using the small arrow at the right of material parameter.

Move the camera, maybe you’re inside or too far away from it !

The fractal is not rendering correctly and there’s noise.

Try to reduce the Step Factor parameter in Fractal material instance. This will affect performance.

If the problem persist, you found a really chaotic parameter combination of the fractal, explore at your own risk!

Shadows on the fractals are behaving strange, how can I fix this ?

Every light source affecting the fractal MUST have contact shadow enabled, depending by the effect desired, contact shadow should be around 0.5.

Play with Contact Shadow value to get a good compromise.

My GPU is on fire and my frame rate is too slow, how can I improve this ?

There’s a few settings affecting the render performance, first you can try disable the “Custom Depth-Stencil Pass” in Project Settings.

Increase the Epsilon in the Fractal Material Instance, this will change the look of the fractal but increase the frame rate

Play with Fractal Settings in Material instance and see what works best. Also be sure that the fractal is responsible for your frame-rate drop.

Change the Fractal material paramete…

Technical Details Machina-Fractals: Essence Project includes : 3 Uber Fractal Formulas materials designed for animation rendering and exploration. 6 Lite Fractal Formulas materials for better performance but fewer parameters, optimized for real-time rendering. 32 Seamless example textures for Triplanar mapping. 32 Color palettes for fractal coloring. 1 Emission texture. 9 Blueprints. Fun. Limitations (for now): No path tracing render. Auto-Focus Shadows are screen space Minimum GPU requirement for real time rendering : RTX 2080 WARNING : Frame rate may drop under 30 FPS with LOW-MID end GPUS. Number of Blueprints : 9 Number of Unique Materials and Material Instances: 18 Number of Textures:95 Texture Resolutions: 4096×4096, 512×512 Supported Development Platforms: Windows, Mac Windows: Yes Mac: Yes Website: www.machina-infinitum.com/unrealengine
