Unreal Engine Marketplace Machina Fractals: Essence V1 & V2

借助 Machina-Fractals：Essence，您可以在虚幻引擎 5 中以前所未有的方式实时探索分形。

对于 UE.5.0、5.1、5.2。

每个分形蓝图有 30 多个参数，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。

总共 9 个级别和 9 个不同的公式，每个级别都可以使用音序器进行动画处理并进行调整以创建最令人兴奋的环境或实时视觉性能，由于实例参数，您可以轻松地实时调整分形参数，在不同的方式或直接输入 3 种颜色渐变。
性能因分形复杂度以及启用的参数和模式而异，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 RTX 2080 GPU 实时渲染，我们建议至少使用 8GB 显存，以便在大多数场景中获得流畅的实时体验。

更新 1：
添加了对所有分形的蓝图支持
MIDI 和远程控制支持
纹理选项
Houdini 引擎网格生成器
通过 Houdini 引擎网格生成器进行碰撞

常见问题
我需要什么 GPU？

我们建议使用 RTX 2080ti 或更快
我看不到分形，我该怎么办？

确保应用材质的静态网格物体具有较大的边界，6000 似乎是一个不错的数字。
将项目设置中的裁剪平面设置为 0.5，然后重新启动引擎。
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。
移动相机，也许你在里面或离它太远了！
分形渲染不正确并且有噪音。

尝试减少分形材质实例中的 Step Factor 参数。这会影响性能。
如果问题仍然存在，你发现了一个非常混乱的分形参数组合，探索风险自负！
分形上的阴影表现得很奇怪，我该如何解决这个问题？

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，接触阴影应在 0.5 左右。
使用 Contact Shadow 值以获得良好的折衷。
我的 GPU 着火了，我的帧率太慢了，我该如何改善呢？

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“Custom Depth-Stencil Pass”。
增加分形材质实例中的 Epsilon，这将改变分形的外观，但会增加帧速率
玩转材质实例中的分形设置，看看哪种效果最好。还要确保分形是造成帧率下降的原因。
改变分形材质参数，你可能发现分形很难渲染！如果它看起来不错，请将其保存下来以备后用。
分形被裁剪到相机中，如何修复？

减少项目设置中的裁剪平面（通常为 0.5）并检查最佳效果，此更改需要重新启动引擎。
当我放大 fractal 时，没有细节了，那又怎样？

在 Material Settings 中增加迭代次数
它是否适用于 VR？

目前，我们在 Bulb Lite 分形中获得了很多乐趣，它对于 VR (RTX 2080) 来说足够快。由于 VR 分辨率渲染，其他公式会有些滞后。
分形在每一边都被裁剪了，我可以改变绑定位置和大小吗？

当然，您可以更改静态网格 actor 中的绑定大小，请务必同时更改正值和负值。
分形在颤抖。

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。

Unreal Engine Marketplace Machina Fractals: Essence V1 & V2

Info:
With Machina-Fractals: Essence, you can explore fractals in real-time like never before in Unreal Engine 5.

For UE.5.0, 5.1, 5.2.

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.

Update 1 :
Added Blueprint support for all fractals
MIDI and remote control support
Texturing options
Houdini Engine mesh generator
Collisions trough Houdini Engine Mesh generator

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 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.
