DOCUMENTATION

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

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?

  1. We recommend using an RTX 2080ti or faster

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

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

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

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

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

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

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

  2. 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 ?

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

  2. 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 ?

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

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

  3. 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.

  4. Change the Fractal material parameters, you may have found a hard to render fractal! If it looks good, save it for a good quality render for later :)

The fractal is clipping into the camera, how to fix ?

  • Decrease the clipping plane in project settings ( usually 0.5 ) and check what works best, this change requires Engine restart.

There’s no detail anymore when I zoom into the fractal , so what?

  • Increase the iteration number in Material Settings 

Does it work with VR ?

  • At the moment we had a lot of fun with Bulb Lite fractal which is fast enough for VR (RTX 2080). Other formulas will work with some lag due to the VR resolution rendering.

The fractal is cropped on each side, can I change the bound position and size ?

  • Sure, you can change the bound size in the static mesh actor, be sure to change both positive and negative values.

The fractal is shaking?

  • Go in Project Settings and set ‘Output Velocities due to Vertex Deformation’ to OFF.

文件

Houdini引擎是网格和碰撞所需的，您可以找到有关如何安装它的指南 这里.

超过 30参数 对于每个分形蓝图，包括可以组合的不同变换模式以及对颜色和发射的疯狂控制，所有这些都遵循分形形状。9个级别，共9个不同的公式，每一个都可以 动画 通过音序器和调整来创建最令人兴奋的环境或现场视觉表现，由于实例参数，您可以轻松地实时调整分形参数，以不同的方式应用纹理或直接输入3个颜色渐变。性能取决于分形复杂度以及启用了哪个参数和模式，但我们决定保留所有参数，以防您想要渲染短片而不关心FPS。

所有分形都使用RTX2080GPU实时渲染，我们建议至少8gb显存，以便在大多数场景中获得流畅的实时体验。

常见问题

我需要什么GPU？

  1. 我们建议使用RTX2080ti或更快

我看不到分形，我该怎么办？

  1. 确保应用材质的静态网格体有很大的边界，6000似乎是一个很好的数字。

  2. 将项目设置中的裁剪平面设置为0.5并重新启动引擎。

  3. 使用材质参数右侧的小箭头将分形材质实例参数设置为默认值。

  4. 移动相机，也许你在里面或离它太远！

分形没有正确渲染，并且存在噪音。

  1. 尝试减少分形材料实例中的阶跃因子参数。 这会影响性能。

  2. 如果问题仍然存在，你发现了一个真正混乱的分形参数组合，探索在你自己的风险！

分形上的阴影表现得很奇怪，我该如何解决这个问题？

  1. 每个影响分形的光源都必须启用接触阴影，根据所需的效果，接触阴影应该在0.5左右。

  2. 玩接触阴影值得到一个很好的妥协。

我的GPU着火了，我的帧速率太慢了，我该如何改进呢？

  1. 有一些设置会影响渲染性能，首先您可以尝试在项目设置中禁用”自定义深度-模板通道”。

  2. 增加分形材质实例中的Epsilon，这将改变分形的外观，但增加帧速率

  3. 在材质实例中玩分形设置，看看什么效果最好。 还要确保分形是负责你的帧速率下降。

  4. 改变分形材质参数，你可能已经发现了一个难以渲染的分形！ 如果它看起来不错，请将其保存为稍后的优质渲染:)

分形正在剪切到相机中，如何修复？

  • 减少项目设置中的裁剪平面（通常为0.5）并检查什么效果最好，此更改需要重新启动引擎。

当我放大分形时，没有细节了，那又怎样？

  • 在材质设置中增加迭代次数 

它适用于VR吗？

  • 目前，我们对Bulb Lite fractal有很多乐趣，这对于VR（RTX2080）来说足够快。 由于VR分辨率渲染，其他公式将有一些滞后。

分形在每一边裁剪，我可以改变绑定的位置和大小吗？

  • 当然，您可以在静态网格体actor中更改绑定大小，请务必同时更改正值和负值。

分形在摇晃？

  • 进入项目设置并将”由于顶点变形导致的输出速度”设置为关闭。
