[Bug] DDS importing crashes

Build 1578757 - K:/TURE/Rocket_CL1578757

Specs Windows 7 Professional English, i7-3770K, 32GB RAM, GTX670 4GB driver 306.23 , UAC off

Description Importing a standard dds file crashes the editor the majority of times. The times it does work the texture shows up as solid white in the editor, and the editor crashes if you right-click it.

Repro Save a texture as dds in PS. I am using standard settings and DXT1 RGB 4 bpp | no alpha. Import it.

Results Crashes the editor instantly most of the times. When it does work the texture shows up white, and crashes editor upon right-clicking it. Each time it crashes log says “has source art in an invalid format”

Expected To not crash. It is great we finally got DDS support back now, and I hope the intention is for it to stay once it is fixed.

Thanks for the bug report! I’ve fixed the potential crash. We don’t support importing compressed textures in UE4. You really want to import uncompressed data. Doing so allows UE4 to select the most optimal compressed format for any given platform.

I’m not able to reproduce the crash but I do get the white texture though. The white texture is being put into our bug database right now.

Can you attach a copy of your DDS file that crashes?

Here is a 512x512 dds file that crashes the editor every time for me. - https://rocket.unrealengine.com/storage/temp/3251-ddstest.zip

Hello, it’s not letting me download the zip file. Can you try to reattach it please? :slight_smile:


Thank you for the asset. I’m still not able to reproduce the issue but I will keep trying.
