simGetImages API causes a Vulcan Error for high resolution images #4339
Description
Bug report
- AirSim Version/#commit: 1.6.0
- UE/Unity version: 4.27.1
- autopilot version:
- OS Version: Ubuntu 20.04
- GPU: NVIDIA GeForce RTX 3060 Laptop GPU, 6GB
What's the issue you encountered?
I see that pixel formats in PIPCamera.cpp have been changed a while ago in this commit: 705a366
This change causes an error if simGetImages API is called for a relatively higher resolution image request (i.e, 2048, 1152). See the error below:
[2022.02.07-08.39.54:241][288]LogVulkanRHI: Error: VulkanRHI::vkDeviceWaitIdle(Device) failed, VkResult=-4
at <path to UE4.27>/Engine/Source/Runtime/VulkanRHI/Private/VulkanDevice.cpp:1344
with error VK_ERROR_DEVICE_LOST
Fatal error: [File:<path to UE4.27>/Engine/Source/Runtime/VulkanRHI/Private/VulkanUtil.cpp] [Line: 958]

with error VK_ERROR_DEVICE_LOST
Segmentation fault (core dumped)
I think the reason is when you switch pixel format to Float, it requires more memory. There is no problem with commits before 705a366
However, after 705a366, the error appears when you request high resolution images vie simGetImages API.
