Importing custom cubemap into UDK

corrosion · Dec 2013

Since UDK no longer supports importing custom made DDS textures, I wonder how I can bring in a cubemap that was saved via ATI's CubemapGen tool?

I solved this by importing individual cubemap faces... (neg X, pos X, neg Y, etc) but I just wish I could do single image.

ya i just export to 6 targa files, bit of a annoying process but whatever, needed if i want properly blurred cubemaps.

Curious, what kind of cubemap did need to convert? I have a Photoshop script somewhere that I wrote, which converts horizontal cross cube map faces into individual files.

DDS cubemap.

It would be cool to have a utility that converted a DDS cubemap with mips into a UDK cubemap with mips.

Well, I guess that would be a horizontal strip cubemap? I actually had a small app in the works that did this

It's actually stored in the DDS as slices. Nvidia's Photoshop plugin will arrange the slices into a strip when it loads. If you tell it to load the mips, they'll be arranged like this:

I'm trying to import blurred cubemap from Ati Cubemapgen with 6 targa files but I don't manage to get the mipmaps with it.

Is there a way to import cubemaps with their mips?

for the most part your best to just import the full quality targas and just let UDK generate the mip maps on import

Does it blur the mips properly?

hypersomniac · Mar 2014

Unfortunately udk blur the mips but seams are realy noticeable. I just would like to know if there was any workaround for this.

Switch to DX11 mode or use latlong maps instead.

I have a 9800GT :'( ... I guess there is no other solution.

Using equirectangular/latlong maps is a solution. The material for those is more complex but given the poor performance of UDK's DX11 mode I still find it superior.
