Car rig breaking when using collision shape.

[relationship-development]

Everything seems to work fine until I add a collision shape. After it tilts up (to match the terrain) for the first time, it never recovers. It remains slightly tilted back on its main axis. Any way to correct this?

Thanks

Hi relationship-developement,

This is difficult to tell from an image. I work from Project files. Those work or not. Images typically require lots of questions* and perhaps even more questions.

*Example (not that I ask for answers to that; I need a file): Is the scale matching the Simulation scale. Are the iterations (etc.) enough to handle it, the distance (Search Radius), and the collision Shapes. Have you tried to use simplified tires? What is the Draw Mode telling you? All of those questions can be avoided with a file.

I can take a look at it., but if you share a file (and it looks larger than 1MB, then please only use DropBox, Wetransfer, Apple, Adobe, or Google Cloud services. Please upload the file uncompressed (no zip and surely not rar). Also, share the URL as is, not shortened or in an HTML wrapper. Just paste in the text. Sorry for the long request text, but safety first.

All the best
