虚幻引擎市场Machina Fractals: Essence V1-V3

Unreal Engine Marketplace Machina Fractals: Essence V1 & V2 包含更新版Machina Fractals Essence v3 5.3
与Machina Fractals: Essence，你可以探索分形在实时前所未有的UE5。

适用于UE.5.0、5.1、5.2 5.3。

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，加上对颜色和发射的疯狂控制，所有这些都遵循分形形状。

共有9个级别，9个不同的公式，每一个都可以用音序器制作动画，并调整以创建最令人兴奋的环境或现场视觉性能，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种颜色梯度。
性能会根据分形的复杂性以及启用的参数和模式而有所不同，但我们决定保留所有参数，以防您想要渲染出短片而不关心FPS。

使用RTX 2080 GPU实时渲染所有分形，我们建议至少8GB的视频内存，以便在大多数场景中获得流畅的实时体验。

更新1:
增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发动机网格生成器
碰撞通过houdini引擎网格生成器

常见问题解答
这个我需要什么GPU？

我们建议使用RTX 2080ti或更快的型号
看不到分形，怎么办？

确保应用材质的静态网格有很大的边界，6000似乎是一个很好的数字。
将项目设置中的剪裁平面设置为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，可能你在里面或者离它太远了！
分形没有正确渲染，有噪音。

尝试减少分形材质实例中的步长因子参数。这会影响性能。
如果问题持续存在，你发现了一个真正混沌的分形参数组合，探索风险自担！
分形上的阴影表现奇怪，我该如何解决这个问题？

每个影响分形的光源必须启用接触阴影，这取决于所需的效果，接触阴影应该在0.5左右。
玩接触阴影值得到一个很好的妥协。
我的GPU火了，帧率太慢了，怎么改善这个？

有几个设置会影响渲染性能，首先你可以尝试在项目设置中禁用“自定义深度-模板传递”。
增加分形材质实例中的ε，这将改变分形的外观，但会增加帧速率
在材质实例中使用分形设置，看看什么效果最好。也要确保分形是你帧速率下降的原因。
改变分形材质参数，你可能会发现一个很难渲染的分形！如果它看起来不错，请保存它以便稍后进行高质量的渲染
分形被剪辑进相机，如何修复？

在项目设置中减少剪裁平面(通常为0.5)并检查哪个效果最好，此更改需要重新启动引擎。
当我放大到分形时，就不再有细节了，那又怎样？

增加材质设置中的迭代次数
它和VR一起工作吗？

目前，我们有很多有趣的灯泡建兴分形是足够快的虚拟现实(RTX 2080)。由于VR分辨率渲染，其他公式会有一些滞后。
分形的两边都被裁剪了，我能改变边界的位置和大小吗？

当然，您可以在静态网格执行元中更改边界大小，请确保同时更改正值和负值。
分形在颤抖。

进入项目设置，并设置输出速度由于顶点变形关闭。

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.
