Hi there. I made a fairly large asset. Although I think it is most likely unrelated but I should somehow mention this.
Fairly large meaning it’s bigger than the standard 525k size map.
The UV seems to bug out when displayed.
Here is the picture of 3dmax view and UV
And then the rocket view and UV.
UV seems to match correctly ( from 3dsmax and Rocket ) but didnt’ render correctly.
This might sound trivial but it really got me searching as to what is the issue. I imported the exact asset into UDK and it displayed correctly.
No no no. I think you guys misunderstand.
Setting out of range UV ( not in 0-1 ) is a normal thing in 3D. It implies repetition. Although it is not intended here but it is not the issue. My issue is that the wrapping isn’t done correctly.
Look at the 2nd Image i’m uploading the island is highlighted in red. it is wrapped correctly in 3DS and even in UDK.
The UV layout also displays correctly in the static mesh editor but does not get rendered correctly. The water portion of the texture should not appear on the Island.
BTW. Just to humor those who think it’s the out of range UV , I’ve adjusted the UV to be within 0-1 and it still makes no different.
I’m not sure what the problem is off the top of my head. If you attach the FBX and texture we can investigate this on our end.
Okay this is disgustingly embarrassing… while trying to send the Asset up I realized I have used the wrong texture all this while… everything was working fine. It’s just totally me feeding it the wrong texture.
It would be great if this post is deleted before I am lynched.
No problem, glad you found the issue 
Looks like it’s because the UV’s are out of 0-1 UV space. Scale it down until you get everything in that checkerboard frame in Max and then reimport into Rocket.
Eh… Ue 4 does not support out of range UV? That is unlikely… Udk supports it.I’ll try it tomorroe Morning nevertheless
UDK had the same behavior : it’s just a display thing. What is out of 0-1 is displayed in red. However this display of the UV has no effect on the mesh itself and you can put things out of the default 0-1 space with no worries.
I would agree that displaying things like this is confusing.
