this asset does not work in new versions of Unity

not work complex mesh collider

The asset seems to have a decent API for using Flex. There are quite a few useful examples and the API supports low level access, even down to indivudal particles. However, the promised integration with SSF doesn't work, at least as in 2019.1. There are a few demo scenes that are named as though they demonstrate using SSF with uFlex and there's a component that contains the SSF-specific render code, but those demo scenes are just copies of the regular SSF particle system demos and don't contain any uFlex components. When I tried adding the SSF Flex renderer myself I found that it's broken (again in 2019.1, but based on the examples I'm not sure it ever fully worked). My guess is that this feature was in development and never finished. I think it's misrepresenting the product to say that it has full SSF integration, and it certainly doesn't work out of the box in 2019.1, so you should be aware of that if you're buying it for that feature. It also uses old graphics APIs, makes a lot of texture transfers during rendering and doesn't work with the new graphics pipelines, which means the whole thing is very CPU-heavy even though the actual solver and renderers are GPU-based. Unfortunately I don't think the SSF implementation would be suitable for most people's use cases. If you just need access to just the Flex API or you want to see a reference implementation of SSF for particles, this might be useful for you.

Amazing asset that works great in Unity 2019.1.1f1, despite it is being released in 2016. I have tried all demos and they works really well.

Unity crashes too often when I try demo scenes. Particles slip throgh or doens't appear when it doesn't work fine, then Unity crashes after I start a demo scene again. My PC is Unity 2017.4, RTX2080.

Works after fixing some of the deprecated functions used in some of the scripts. But even then it runs really slow, it takes a very large chunk of the render time. (over 4ms. with an NVidia 1080 and 32gb RAM) It does its job but it's very performance heavy. I have no use for it personally and would like a refund, however, I bought it over a year ago, and I have yet to check whether or not it's possible.

Unfortunately the last update was in 2016 And it is not support AMD Radeon I do not think this tool useful for now But if it will be updated , It will be great

@Dynamite3D Can you tell the very very tricky way to configure the huge size to a more desirable size of the flex object?

It's an interesting asset, but cannot be used for serious purposes I think. The scale of everything is HUGE and is very very tricky to config it for normal sizes. The usability and UX simply doesn't exist. In addition I have a problem of compatibility with VRTK (a VR toolkit) and asked for help to the developer of uFlex and still waiting for a response. Not recommended if you have something more than curiosity.

The editor window does not open at all, most paths are hard coded and not relative to package folder. I had to debug and fix the code to get running and even, running is a generous term. I get lots of error when generating and barely gets something working. I agree with the previous comment, this is not production ready at all, it needs a lot more work.
