[Bug?] Textures sometimes not rendering in standalone game mode

We’ve been noticing that our textures sometimes don’t show up and are replaced with default textures, but ONLY in standalone game mode. When we use Play As > New Window or view it in the editor, everything is fine.

Why might this happen? Could it be something we’re doing?

Oddly, I’m finding that textures sometime fail to render on the exact same static mesh with the exact same material.

Take a look at the attached images. One shows the super-simple material we’ve built; the other is a screenshot of a benchmarking / test level we’ve set up, while running in Standalone Game mode. Notice how the frame on the left is textured properly and has text on it, while the ones on the right just have the default material.

So somehow, my pulling that one piece on the left away from all the others made it have the right material, while the other ones do not. And I haven’t modified any of its properties in any way relative to the others (except its position).

And again, if I run it using Play In > New Window instead of Standalone Game, the problem goes away there, too.

I had thought this might be due to a need to rebuild lighting or the fact that I had “Force No Precomputed Lighting” set in the WorldSettings. But turning off that flag and rebuilding the lighting actually reset everything to the default material.

As far as I can tell, this is now fixed in beta 6.

I am glad this got resolved for you. This was an issue we had seen in the past that I was trying to track down the fix for. Possibly however the root problem is fixed now.
