Cesium for Unreal v2.1.0 - still missing tiles at the edges in VR

[Kevin_Ring]

Thanks @Lildreas. By any chance are you able to reproduce the problem outside of the Varjo? Perhaps by using a different/unusual aspect ratio for your window?

The code that computes the view parameters is here:

You could try stepping through there in the debugger on the device and see if anything jumps out at you as wrong.

There’s no direct way to change the frustum size. But the CesiumCameraManager Blueprint API can be used to provide custom camera parameters (including field-of-view). So you could write a Blueprint that provides Cesium with a widened one. This post is the best documentation we have at the moment for using this API. It’s solving a different problem, but hopefully will give you a sense of how it works:

Tiles not loading at edge of render area

I’ve never actually tried myself to use the CesiumCameraManager to deal with Movie Render Queue aspect ratio problems (though Nithin did when he first added the feature), so I thought I’d try it. There were some unexpected gotchas, but it worked well enough in the end. Here’s what I did. First I added a new Level Sequence and added a Cine Camera Actor to it. I set up a simple flight for the camera with two keypoints. Rendering with the Movie Render Queue now works fine, because the default Cine…

Merry Christmas to you as well!
