## **Overview**

---

By default, all the Anima features should work fine in Unreal Engine after a standard installation. However, as Unreal Engine is a very complex software that can be used in several environments and even multiple Industries (like *Architectural Visualizations*, *VideoGames*, *VFX*, *Virtual Reality*, *Realtime Broadcasting*, etc), in this article we have collected a list of **known issues** and **tips** that may help you get better results using our Anima plugin.

### **Avoid Crashes on UE Start After Updating Anima**

---


---


All those files are generated and placed in that folder to be later included in the package you are building (when you use "Launch", the project is also built on-the-fly).

The problem appears when you install a new version of Anima because those files are left there by Unreal and, the next time you start your UE project after updating Anima, the Windows SO may mix some of these older DLLs with some new ones from the updated Anima plugin, and that is what causes the crash.

The **solution** to this problem is simple: **remove all the contents of that folder before loading the project**.

Those are temporal files that are recreated each time you create a new build, so it won't make any difference to remove them. Actually, we don't know why Unreal chooses to leave them there after the build is made, it would make more sense to remove them automatically. In any case, that is something that depends only on the workflow that UE chose to follow, so we can't interfere there.
