Change texture of RawImage

Question

Hello. I have an issue that has been bugging me for a while now. First, what I want to do: We want to change the picture of one RawImage component depending on what map is picked from a Dropdown menu that is called MapSelect which has options on it. I have tried everything that I can to change the image on MapPicture including trying to change its sprite texture with if (MapSelect.GetComponent().value == 0) { MapPicture.GetComponent().sprite = RandomPicture; } (if they haven't selected anything yet) this gave me an error so I tried this paired with a RawImage on the MapPicture GameObject instead of an Image property (yes, I did have the picture as a Sprite 2D and UI) and I declared the MapPicture as a RawImage and I set the RandomPicture as a Texture paired with this line of code: if (MapSelect.GetComponent().value == 0) { MapPicture.GetComponent().texture = RandomPicture; } and it doesn't give me an error. I think it might just be the way I'm setting up the if statement that is checking the value of MapSelect because I had previously put a print() statement within these and it didn't even run. I just have no idea what is going wrong. Thank you for the help. alt text

@IgorSimovic I just tried doing it this way and was getting an error on it so I looked at the documentation and in the most recent version of Unity this was removed. Do you have any other way of solving it perhaps? Thank you.

This works for me:

Convert texture to appropriate derived class and call Apply method

 public RawImage rawImage;
 rawImage.texture = ScreenCapture.CaptureScreenshotAsTexture();
 (rawImage.texture as Texture2D).Apply();
