UnityWebRequest for over 4K images

I have been using UnityWebRequest for ages without any problems retrieving images. But when the images are over 4096 pixels wide the handler returns a purple image (but the request success without errors and the amount of data seems correct)

I really need to use UnityWebRequest because it does the texture decompression on the background and I am working in a VR project


Note: I have tried with Unity 2017.3 and 2018.1

 

Yes it does,
if I use something like

Code (CSharp):

1. Texture2D rawTex = (request.downloadHandler as DownloadHandlerTexture).texture;
2.                 Texture2D t = new Texture2D(rawTex.width, rawTex.height);
3.                 t.LoadImage(request.downloadHandler.data);
4.                 mat.SetTexture("_MainTex", t);

I get this

but if I directly assign rawtex I get

This happens as soon as the image goes over 4096 pixels wide (these are pano images so they are pretty wide)

 

I don't see how the format relates to the RGB format really. Something as simple as opening the app in paint, and saving a a 1k version loads, but transforming it to >4k doesn't and that should be the same format? I suspect something related to the buffer size or something like that used internally to decompress the image?

Has this bug been fixed? I can't find the bug report Mephesto_Khaan created.

It is still a problem in 2017.4.16f1.

 

Thanks for the reply.

What is the maximum Content-Length currently supported by UnityWebRequestTexture?

 

Just ran into this. Thanks for loggin the bug and providing a workaround (performance hickup is acceptable for my usecase)
