Cubemap madness!

barnesy

Hey guys, I have ran into another problem.

I found this nice little tutorial about making custom cubemaps but mine doesnt seem to work properly

In the newer versions of UDK it doesnt have the RenderToTextureCube so I have had to try using either TextureRenderTarget2D or TextureRenderTargetCube.

I tried using the TextureRenderTarget2D as it created the same green picture that he used in the tut , but I could not apply it to my sphere for some reason



I could apply the TextureRenderTargetCube though , but it created very strange results.

For some reason only half of the environment was reflected , and it kept rendering a single part of the floor , despite being moved around etc

If anyone can point me in the right direction I will be extremely grateful

Thanks

Can you link to the tutorial you found so we can try and follow it as well? It may help with diagnosing your problem.

Ahhh my bad I thought I included it

2 minutes in is where the madness begins

It might be a different SceneCaptureActor for cube textures, there's several different types. That looks like it's only updating one face.

I had a simillar problem.

I ran through the tutorial and had working results so the tutorial is correct from what I can tell. I'm not sure why your cubemap is not updating and also why it is only reflecting one area. I can see that your far plane seems to be cranked up as well. Try and set the number on your far plane to a flat number such as 1,000,000 with no decimal place or numbers thereafter. Also as a side learning note,

SceneCapture2DActor - Captures from a specific angle (like a camera or rear view mirror)

SceneCaptureCubeMapActor - Captures reflections from the 6 cardinal directions for use with cube maps

SceneCaptureReflectActor - Creates reflections over large surfaces (This is commonly used for reflections on tile floors or otherwise shiny surfaces. Resize the plane it creates to capture the surface area you desire.)

I dont know if you looked at my thread or not, but check if you are in DX11 or DX9. Since SceneCapture actors dosnt work in DX11 unless they fixed it since my problem.

What you can do is switch your renderer to DX9, SceneCaptureCubeMap will function right, then right click on your TextureRenderTargetCube and select 'Create New Static Texture'. Then switch back into DX11 - given its not realtime reflections, but this might work for your purposes.

I ran into the same issue where you get to the part of the tutorial where you link the actor to your TextureRenderTargetCube, the texture doesn't update like it does in his tutorial. If you simply ignore this and create your Static texture anyway, it works no issue.
