Assertion in Cook

Hello devs.

I get this build error:

I am using an Unreal engine patch from this :

#### Description Added a new sensor - fisheye camera. Fisheye image example: ![orig_sky](https://user-images.githubusercontent.com/14319065/103095443-a6195b00-4611-11eb-9b3a-5a05034f1456.png) Fisheye camera works better with the following BP_Sky settings: BP_SKY -> PostProcces -> PostProccesVolume: 1. Film -> Toe = 0 2. Exposure -> MinEV100 = 6 3. Exposure -> MaxEV100 = 6 4. ImageEffects -> Vignette intensity = 0 5. RenderingFeatures -> AmbientOcclusion -> Intencity = 0 6. Screen space reflection -> Intencity=0 7. Light Propagation Volume -> Intencity = 0 ![custom_sky](https://user-images.githubusercontent.com/14319065/103095451-ab76a580-4611-11eb-8099-129830a20416.png) As an example fisheye sensor is added to the sensors list in manual_control.py and can be used like other camera-sensors. `['sensor.camera.fisheye', cc.Raw, 'Camera Fisheye', {}]` Fisheye sensor attributes: - x_size, y_size - image size - max_angle - maximum angle - d1 - d4 - distortion coefficients - c_x, c_y - optical center - f_x, f_y - focal lengths For ex. (attributes used for images above): `bp.set_attribute('x_size', str(1280))` ` bp.set_attribute('y_size', str(720))` ` bp.set_attribute('max_angle', str(210))` ` bp.set_attribute('d_1', str(0.08309221636708493))` ` bp.set_attribute('d_2', str(0.01112126630599195))` ` bp.set_attribute('d_3', str(-0.008587261043925865))` ` bp.set_attribute('d_4', str(0.0008542188930970716))` ` bp.set_attribute('f_x', str(320))` ` bp.set_attribute('f_y', str(320))` ` bp.set_attribute('c_x', str(640))` ` bp.set_attribute('c_y', str(480))` In UE4_patch_fisheye-sensor.zip you can find a patch for UE4 which is obligatory for the fisheye sensor. [UE4_patch_fisheye-sensor.zip](https://github.com/carla-simulator/carla/files/5739990/UE4_patch_fisheye-sensor.zip) #### Where has this been tested? * **Platform(s):** Ubuntu 18.04 * **Python version(s):** 3.6 * **Unreal Engine version(s):** 4.24 --- This change is [<img src="https://reviewable.io/review_button.svg" height="34" align="absmiddle" alt="Reviewable"/>](https://reviewable.io/reviews/carla-simulator/carla/3755)

And it introduces a new element in Engine/Shaders/Private/SimpleElementPixelShader.usf
It has been built and working with 4.24 and I made changes for it to work with 4.26. But I get this strange error at the end.

Hey!

I found my answer here: Assertion failed: AlignedOffset == TypeLayout.Size

Its because the macro LAYOUT_FIELD is not used.

So long…

HELLO ,I am confused with same fisheye camera sensor problems in carla ,can you tell me how to fix it ? can you send the changed cpp files to me fulei1010@126.com ,thank you very much.
