Unity uses NVIDIA flex for unity plug-in to realize the effects of making software, water, fluid, cloth, etc. learning tutorial

Preface

Because of the function of work , Query the plug-in ; The plug-in was not selected after downloading , But here I will share the learning process , Convenient for latecomers to learn ; I feel that this plug-in has stopped updating , However, the plug-in is still very powerful ; I don't know whether it can really achieve the effect of promotional video through this plug-in , I feel that it may be possible to spend a certain amount of time .

Publicity effect

Plug-in effect

Installing a plug-in

Only need to .unitypackage Just drag the file into the project .
After importing successfully , There will be one more menu at the top NVIDIA Options ：

You can add components and create resources .

and Project The right button of the window will also have one more NVIDIA Options ：

You can create Assets.

The plug-in USES

In the engineering of Assets\NVIDIA\Flex Samples There will be cases under the directory , You can view it directly and quickly ：

Assets\NVIDIA\Flex\Actors Under the directory, there are component scripts for various effects ：

Assets\NVIDIA\Flex\Assets Under the directory are resource scripts for various effects ：

One of the most special is FlexContainer resources , Basically, every effect component script needs a FlexContainer resources , Similar to effect container resources , Can be found in Project Right click in the window > Create > NVIDIA > Flex > Flex Container establish ：

FlexContainer The resource attributes are shown in the figure ：

You can set the maximum number of particles , Attributes of a single particle 、 Global gravity 、 Cloth properties 、 Fluid properties, etc .

Here we will try two effects .

software

stay Assets\NVIDIA\Flex Samples\4. Soft Actor\Scene Make in the scene .

stay Project Right click in the window > Create > NVIDIA > Flex > FlexSoftAsset New FlexSoftAsset, software Boundary Mesh choose Cube：

And create an empty node , newly added Flex Soft Actor Components , Associated with the newly created New FlexSoftAsset And before Flex Container：

After the operation, it was found that the previous cylinder disappeared , Only new Cube：

I tried to create a new one Flex Container, stay Project Right click in the window > Create > NVIDIA > Flex > Flex Container establish , And will NewFlexSoftActor Of Container Set to new Flex Container, Now it's normal ：

According to the above test , It means different Flex Soft Actor Need different Flex Container, Otherwise, one will not generate .

Fluid

stay Assets\NVIDIA\Flex Samples\9. Fluid Renderer\Scene Test under the scenario , In this scenario FlexSourceActor Realize a source of fluid , It can continuously produce water flow ：

Here is a new water body , Create a new one FlexArrayAsset resources , And select Boundary Mesh by Cube：

Create a new one FlexArrayActor node , And the new FlexArrayActor and FlexFluidRenderer Components ,FlexArrayActor Represents a scalable group object ,FlexFluidRenderer For rendering as fluid . The original Flex Container And the new FlexArrayAsset Related to FlexArrayActor Components ：

Then check the running effect ：

In this way, you can share one Flex Container , Now I'm completely confused .

summary

This plug-in is still not suitable for projects , And a little bit more , It may only be applicable to NVIDIA graphics cards PC platform （ This is speculation , It hasn't been verified ）, Mobile platform is impossible . Only one Beta Test version , After the Assetstore It's also off the shelf , therefore , The test is ok , Others should be cautious . There will also be various errors （ But it works ）：

Another point is that many of its codes are encrypted , For programmers, I haven't found some effect control , I don't know how to control the coding . Of course, I'm looking forward to its improvement and commercial use , It should be strong .
