Hi,

The batch option requires to download and optimize an AI model (like any object detection model) at first launch. It is not very well handled in the Unity plugin and it looks like a freeze/crash. I would recommend to run the object detection bird view sample (with the Batching option enabled : https://github.com/stereolabs/zed-examples/blob/master/object%20detection/birds%20eye%20viewer/cpp/src/main.cpp#L40 ) once. It will download and optimize the model while printing without looking like a crash (you have some infos the console explaining you what is going on).

Best regards, Benjamin Vallon

I have run all the samples and have the AI models in the stereolabs/resources folder and their optimized versions. This is not the problem
