Hi all,

Can't find this answer in the FAQ, and couldn't find proper support information - so hopefully the right spot.

Bought this for a VR sim to handle a small part (I'd like this project done tomorrow) BUT lo and behold when I went to use the plugin ... I didn't read carefully and it looks like it doesn't support 2018.x packages - only Unity 2019.2.9 and later.  I couldn't find a way to get immediate help, and the website / info keeps redirecting here. I'm a bit nervous about relying on this because the forums seem inactive, and there posts haven't been getting responses for a few days ... but here goes.

I'd like to know how we can get the earlier 2018 version? 3.2 worked fine for desktop use and 2018. I won't update the entire VR simulation for the support of a rope plugin, but am hoping there is a quick solution without removing Obi and finding something else. I can't downgrade the 2019 version either, because it was serialized in binary with the 2019 serialization format. So yeah.

Just upgraded to 5.0 and wanted to take a look at the new sample scenes to look at the new way of doing things.
Neither cloth or rope sample scenes load. 
Instead unity instant crashes ( without even showing the error report sending button ).
The unity log just shows these as the last log lines:

Opening scene 'Assets/Obi/Samples/Cloth/CharacterCloth.unity'

Probably need to revert to obi 4 for the time being. The dangers of using unity alphas I guess. Hope it's easy to fix.

Btw: Apparently unity changed the way packages work also. If I import cloth package then rope package the second package tries to delete all the scripts from the cloth package not included. So I had to copy the cloth folder out of assets then import rope and then merge the folders in the explorer.


EDIT: Tried creating a cloth blueprint. Samish error but full stacktrace:

Hi,

I'm encountering a recurring problem with Obi 5.0 and Unity 2019.3:

No matter if the "enter playmode without reload" option is activated or not, Unity will sometimes (up to 80% of the time) entirely freeze when activating the Obi Solver object. Since it's a freeze, unfortunately, I have no error log and I can't seem to isolate what exactly causes it to happen. 

All I know is that if I load my scene with the obi solver disabled, it loads, but if I load it with it enabled, it doesn't.

I will try to investigate a bit more, but I wanted to mention it here so you know about that issue.

Small precision: I have multiple scenes loaded, the examples since to work fine on their own

Will the LWRP / URP mode support "Single Pass Stereo"?

I really hope it is possible so we can use it in VR with higher performance. Someone on youtube tried to use 2 camera for VR but the result was a little buggy.

So I'm just wondering if it is something that will be possible sometime in the near future?

Thanks

Hi, I'm using Obi Cloth 5.0 with Unity 2018.4.9. I'm profiling a scene with an Ambient Force Zone, Late Fixed Updater, and a Skinned Cloth. I seem to be getting some pretty massive spikes in RunLateFixedUpdate(), specifically in Substep and BeginStep, going from around 0.5ms up to 15-30ms. Any ideas on why this could be or how to resolve it? The solver is using only Distance and Skin constraints, with 1 iteration each. The spikes persist even when I disable the force zone and skinned cloth and have nothing in my scene enabled except for the Solver and Updater. I've also tried commenting out the lines UpdateColliders(), UpdateAllRigidbodies(), UpdateAllVelocities() in Substep() as I'm not using any colliders or rigidbodies, with no effect.

Hello,

I am really enjoying Obi fluid.
Are you guys plan to make it support for the tvOS at some point?
As far as I know, iOS and tvOS are not that different architects but it won't be built for tvOS from Unity because of namespace errors.
Is there any walk around like build to iOS and convert it on Xcode or something?
Please let me know.

Thank you!
Have a wonderful day.

Hi

I'm making a game where you crush / squash objects. The problem I'm having is that once the objects are squashed or otherwise heavily deformed beyond their original shape they start to float around erratically. I'm guessing this is because the particles go inside each other? I've tried disabling self collisions in the obi softbody component. It helps a little but doesn't completely solve the issue. Is there a way to avoid this behaviour?

hi josemendez,
I bought Obi cloth 5.0, and watched the strength scenes and documents. When simulating the cloth, there was a fall. As shown in the figure, my settings are the same as the example scene "charactercloth". I can't find the cause of the problem. I hope it can help me. Thank you.

I keep getting flooded with the error below and don't really know what to do since I can't even figure out how to use your tool properly. It happens when I enter Edit path mode with a newly created Solver/Rope GameObject which has a Very Long Cable Blueprint applied. Edit mode itself is missing all gui's but I can see/modify control points.

I just bought this today and I'm pretty disappointed that there are no quick, easy to follow tutorials (that get updated). This tool is more complicated than it needs to be, so there should be better documentation and tutorials available to get people using it quicker.
