If Recast Graph “Rasterize Trees” is enabled, it includes trees that have IsTrigger enabled. This is incorrect behavior. IsTrigger is specifically provided for objects that do not interact with physics. The IsTrigger collider is for click interactions and raycasts which have the IsTrigger flag enabled…
An example of where this behavior is incorrect is non-obstructing vegetation that is interactive. e.g. a bush. In survival/crafting games such as my own, players may pass through bushes and harvest them for resources.
You may want to add a RecastNavmeshModifier to those vegetation, set to ‘Always Exclude’
Thanks. This was indeed a bug. I’ll include a fix in the next update.
In the meantime, adding a RecastNavmeshModifier set to Always Exclude, as @tealtxgr mentions, will work around the issue.
