[RELEASED] RayFire for Unity. Runtime demolition and fragmentation plugin.

Hi @Mir-vadim!

Thanks for the feedback and workaround! For now with that knowledge in mind this is enough to get us by till the next update material wise

However we have run into another issue. When using the reduce keys function we have a set of meshes that immediately shift out of place no matter how low we set the threshold. it seems we are automatically missing the first set of keyframes from any animation we record or animations that are supposed to start later happen immediately on start.

This occurs no matter how high or low the frame rate of the recording is set. From 3 to 45 the issue is the same, if not exacerbated by the higher frame rate.




This is actually a fairly important issue on our end, Is there something we are missing in our settings or is this something that can be fixed?

 

Hi, yeah, I fixed this issue, in the attachment you can get fixed scripts.
Put them in Assets\RayFire\Scripts\Components and Assets\RayFire\Scripts\Classes
accordingly. Let me know if you still will get problems with reducing keys.

 

Hi @Mir-vadim,

The start animation issue no longer seems to be a problem, Thanks! To confirm from our tests, the higher the threshold is the less compression is applied?

Also, the animations seem to feel slower during playback, as some of the debris seem to drift toward the ground rather than follow the animation as expected.

Is this a side effect of the key reduction?

 

Nice
The higher threshold the more keys will be removed. With 0 threshold it only removes keys if neighbor keys has the same value. WIth a positive threshold it starts to remove keys with little difference. Keys reduction doesn't change timing of keys, so I don't think this is because of key reduction. Did you test playback for these debris with reduced keys and without?

 

Hi,

Can you repair the demolition? e.g. Break cube into x pieces, then repair cube to pre demolition state (worst case scenario I guess would can create a duplicate of the original cube.

 

Hi, there is Reset feature in Rigid component which lets you restore demolished objects. You can also keep all fragments or meshes which were created at first demolition and then reuse them as well. when object will be demolished again.

 

Hi.
Preliminarily: RayFire Shatter... then
Object Type : Mesh Root (At Start, Dynamic, Runtime)
Fading : (On Demolition &, || On Activation), Fide Type (Scale Down)... not work. Why? ( Connected Cluster works well)

 

Step by step text tutorial pls. how to break an object from a collision or event from empty scene? How to prepare object (solid mesh or it doesn`t matter) scale...ect. the minimum set of components of your asset, which of them i need to add for basic destruction, where the components of the asset should be duplicated, if necessary. Can all the preparation for simulation be done without pressing the play button (in editor mode)... When to wait for help, documentation, tooltips that explain the work of the asset, and is easy to use Rayfire from scratch.

 

Hello, is there any way to delete the LODs when destroying an object or will I have to do this on my own using scripts?

 

Hello, I believe RayFire does not support IL2CPP backend scripting right, because when i build my game, the error log shows some rayfire components, but I guess it will come when the support for other platforms arrive?

 

Hi @Mir-vadim,

We did and apples to apples comparison and discovered that the threshold if set too low seems to have some kind of slowdown effect. Not sure why. It doesn't show up in the original animation with compression.

That said another quirk on our side with the script, the higher the threshold, the less frames it compresses. It still works mind you just opposite of what I expected. Also, High FPS animations are less susceptible to the compression issues than low FPS animations. I have to Drop the the threshold below 0.0001 to get the same kind of slow down inconsistencies I was before for 3, 5, and 15 frames.

I suspect something else might be at play here, are there any changes incoming in the next update that could be affecting this? We are using Unity 2020.1.8f1 if that is helpful.

 

I recently bought this plugin and it's really fun to play around with.
Are there any Cool demo's out there of things that have been made with the help of Rayfire in Unity?

 

Hi, sorry, but I didn't create yet such demo, mostly because I am not a game developer and it will need a lot of time which I can spend much more useful by fixing bugs and adding requested features. Most of requested features were added so now I have some time for documentation and hopefully I will create some demo using free Unity game assets.

 

Hi, We didn't test IL2CPP yet, but can you send me this error log?

 

Hi, for now there is no special support for LODs, this is requested feature for next release, or for release after next release.

 

Hi, I am working on new documentation at this moment and there will be a bunch of text HowTo tutorials that will cover the most used features. I will try to release the next build with new documentation in 2-3 weeks, will work on them during New Year holidays.

 

Hi, will test such combination. but can you provide more info, please? So it demolished every child of object with Mesh Root rigid using Shatter properties but these fragments do not fade down by scaling?

 

Just tried this setup and all works ok for me, seems like you are missing something in your setup. Can you describe what happens after you start play mode and what you expect to happen?

 

I will test this threshold issue better next time. This feature can not be affected by Unity version, it simply deletes keys if they do not differ too much from its neighbors. And it is really weird that animation with threshold looks slower because it doesn't change key position on the timeline.

 

I totally understand, my purpose with the question was open to everyone on this forum, if someone would like to share some cool video of the work they are doing.

 

How optimized if at all is this for mobile?

 

Users who tried it on mobile report that performance is good, but as always in such cases, I can send you full package to try it by yourself before buying. Let me know if you are interested.

 

Hi. Increase solidity. Shards of the first level do not disappear. The others disappear. For Connected Cluster, the first-level shards disappear. Maybe that's what it's meant to be.

 

Hi, connected cluster should not have second-level shards, only one level. To use several levels you need to use Nested Cluster. I will test such behavior and maybe will add some warning, but Connected Cluster creates Shards only for first level children.

 

hello @Mir-vadim
I am using the asset and having crashes for unity 2019.2.0f1, latest asset and Mac OS 10.15.7. after reimporting it started to working great but dont know, if it will crash again or not.
Lets say i want to make effect like shatter object from static blade(cube or cube base collider), when ever Rayfire Rigid touches the collider. i.e chopper shattering some objects when it touches the blades from up to down motion.

 

hi, let me know if it will crash again.

As for the second part of your message, is it a question how to create what you mentioned? Or this is what you did when it crashed?

 

I've finally got around to test this, and it does work (no more build issues on Linux), but I'm guessing I won't be able to use the library on Linux, is that right?

 

Yeah, we need to compile special libs for Linux.

 

I want to create that mechanism. also i want to ask is there any way that i can shatter object and make prefab out of it with sub parts?

 

Hello,
thank You for the great plugin.
Please,if You can help or if someone knows,how to do this properly:

Im using Connectivity like in your tutorials, parent with Connectivity and all chunk meshes as children.
Is it possible to reset the whole structure when using clusterize?
Or without it?Can i reset and reuse these in runtime somehow?

When i reset the children,then reset the connectivity,gizmos show its connected again,but the collapse isnt working anymore

Thanks a lot and keep it up,i love the package

 

Hi, to be honest, I didn't test Restriction component with Connectivity which clusterize a group of fragments. For now reset works only for Mesh and Cluster object type, so I think I will need to add special Reset button inside Connectivity component since it manages all children. So, unfortunately, for now I suggest you to destroy and instantiate whole structure, but I will add Connectivity Reset in next build.

 

If you want to shatter object using Blade then you need to set Action Type in Balde to Demolish instead of Slice.

As for making prefab, after you fragmented object using Shatter component you need to export fragment's meshes into Unity Asset so it will reference meshes to this asset, then you can create Prefab with all fragments.

 

Thats very nice,im looking forward.Thanks for the fast reply.If You happen to find any tips and suggestions for this use case,let me know here.
I very much need just the connectivity to setup connected cluster from children just as in your tutorial scenes,RayFire may be a bit overkill just for this,but i really like what you do and would love to continue using it.

EDIT: not only reset, but runtime setup of the cluster, for procedural structures, if that is possible

 

Hi, Just checked and Connectivity component can be applied in runtime and it worked well, creates connected structure. Or did you mean something else?

 

Hello
Then its perfect.Thats what i meant.
I was trying to enable the connectivity component or initialize it somehow, but not create it at runtime.
Structure was created,but was not breaking correctly,nevermind.
Testing asap again and will edit this post with result.

edit: It works, but it was a stupid idea for workaround, i need to reset it anyway, i will leave it for later

 

Has multithreading been implemented in runtime fragmenting?

 

We are using Rayfire for Unity for Empire of Ember. We have modified the code so we can batch fragment at editor time on prefabs or scene instances.

You can see in the trailer video where Rayfire was used.
https://store.steampowered.com/app/980640/Empire_of_Ember/

 

That is great Thanks for letting us know.
You can describe how exactly you edited code and for what so maybe I will add the same functionality in plugin.

 

Hi, yes it is implemented but there is no much use out of it because you can start seeing benefits of multithreading when there break object to a lot of fragments, about 100, this is when there is advantage for spreading fragments generation over several threads. But for now you can demolish only low poly objects for 20-30 fragments in runtime in order to keep framerate high enough, so multithreading support not so useful as we expected it to be.

 

Hi @Mir-vadim! Great asset

So I am using a pre-shattered asset in a zero-gravity environment as a dynamic connected cluster (think spaceship), and it works. What I'd like to see is the ability to set the activation to offset. The problem as far as I can tell is that activation via offset is offset from worldspace, not localspace relative to parent. The result being that the root Rigid object cannot be dynamic AND use activation by offset as offset is strictly relative to worldspace.

Is this the case or did I miss something?

 

Hi. Well, this is how activation works, I mean the word itself means that it activates something that is not active = inactive = not dynamic object. I understand what and why you need but I guess I need to add something different for what you want to create. If you want to have a dynamic connected cluster and then start to detach its shards (single piece of the cluster) you can start to shoot it at these shards, in this case, Cluster will be demolished and these shards will be released and get their own Rigid component and will be simulated separately. But detaching them by offset is not considered for connected cluster because again, this is whole point of using cluster, it allows to simulate group of object as one solid object and then demolish it step by step.

 

Yeah I figured that was the case. I was just hoping to get a beat-up / dented look before shards started detaching. Thanks for the clarification!

 

Hi,

I'm seeing a crash of Unity when using the blade (crash also occurs on mobile phone). The crash is not 100% deterministic but it happens very frequently whenever I slice an object 3 or 4 times. I noticed the following stack traces (two separate crash logs from Unity's Editor.log):

I didn't do anything fancy - simply copied the RayfireBlade and RayfireRigid components from the blade sample scene.

Rayfire version: [1.28]

Any idea?

 

Hi, we fixed recently Slice crash in DLL, but for now only for WIN 64 platforms. If you use plugin on Win64 I can send it to you to try and see if it helps.

 

Good to know thanks. I use Unity on Mac (and releasing on iOS). Do you happen to know ETA of the fix for the mac?

 

Should be ready by the end of this week, sorry, we have some difficulties with Mac setup right now, need some time to setup again and test everything

 

Good day RayFire team!

Rayfire looks promising and I've been learning lots through video tutorials and trial and error.

Is there a way to use "atlas"-ed materials with the shattered inner material? I get the entire atlas material applied to the inner shattered pieces. It'd be nice to apply just a rectangle within the atlas to the shattered pieces. The same idea could apply to debris too.

 

Hi, sorry, didn't get email notification. I didn't check it with atlased materials. I will check this a bit later and will try to add such support in one of the next builds.

 

Thanks for your reply, that'd be great to have in the future!

 

Hi

I updated to Rayfire 1.29 today and my generated xcode project comes up with some build errors. 2019.4.11/IL2CPP.

It seems to be an issue with the new 1.29 version of this file libRF_CNative_ios.a (112mb) in the plugins folder
The Rayfire 1.20 version of this file libRF_CNative_ios.a (240mb) was working before i updated.

I managed to get past the xcode build errors by using this old version in the generated xcode project instead.
