  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Vehicle wheels don't turn/all turn/crash?

Hello all!

I am having problem with my vehicle that I have created, I can't seem to get the wheels to turn correct and with some configuration on the wheels, UE4 crashes.

I have tried according to this tutorial, https://docs.unrealengine.com/latest/INT/Engine/Physics/Vehicles/VehicleUserGuide/

I have tried setting up the vehicle according to this,https://docs.unrealengine.com/latest/INT/Engine/Physics/Vehicles/VehcileContentCreation/

I have followed this tutorial on youtube, https://www.youtube.com/watch?v=9yrHqMBynlw&feature=youtu.be

Here are some pictures of how it looks like:

In the two pictures below, I am turning right.(Different wheel and wheel bp setup)alt textalt text

In the picture below, I am turning left. alt text

I have read through all of what I have found on the answerhub and the forums and I haven't been able to find anything that helps.

I have tried (some examples): - With or without bones - Different FBX exports (i.e. 2014, 2013 etc.) - Deleting history in Maya before export - Moving bone and/or pivot to 0,0,0

Have tried all kinds of things I have found around the forums etc. but nothing has helped.

Modeling software: Maya 2015 Windows 7 Sp1

I am thankful for all the help and tips I can get :)

This seems like an issue with the order you named the wheels in your vehicle BP. Can you post a screenshot of your wheels setup in the vehicle BP please?

Also if you make a new project based on the normal vehicle templates, the sedan it comes with will have a skeleton like this that rotates and turns the front wheels. You can pick apart how it's rigged and animated and make yours match that. Or even import your mesh as skeleton mesh and believe you can tell it to use the sedan's skeleton as long as you named your pieces the same way as the sedans.

Thank you for your replies! I have posted in the forum about this too, and Geodav managed to help me to get it to work. Thread: https://forums.unrealengine.com/showthread.php?55825-Vehicle-disappearing-when-turning It had to do with orientation of the pivots and bones of my model. I named the wheels in order: 1 left front 2 right front 3 left rear 4 right rear It was according to the vehicle template :)
