Obi 7 has been released

[Ben_bionic]

Hi Ben,

The behavior of ChangeLength has changed in Obi 7, the parameter passed is now a change in length, not an absolute target length. Passing "1" will add one meter to the current length of your rope.



I'm unable to reproduce this. Swapping the ObiExtrudedRopeRenderer with a ObiRopeChainRenderer in the sample Crane scene works well for me. The chain can change its length and new links are added/removed as a result, the chain doesn't go away:



Keep in mind that chain rendering now uses GPU instancing, so the material you use to render the chain must support GPU instancing. Otherwise an error will be shown in the console and the chain won't be rendered. See:

let me know if this is still an issue,

kind regards

looks like the issue I was having was that I had messed with a few things and was changing the length by to much. If you change the length by a large margin as I was doing to try and start with a lot of slack in the chain it would just go away. I now just do it a few times over the first few frames and get the result I was looking for. The only weird thing with chains that I am now fighting with is with the default chain I change it to compute and I get one chain link. I checked and the material is set to "Enable GPU Instancing" but even in the example compute shader scene if I change to a chain renderer I only ever see one link.
