Maya n Unreal

Muk

I saw there was a thread with Max + Unreal - with useful scripts and workflows. I'd like to know if somebody has suggestions for Maya + Unreal.

First problem I've encounted is that I've been spending too long time on my lightmaps, there must be a better way. Does anyone have a script that layouts my UVs with 2-4 pixels between each shell, and fills UVs to the border?


I am using Maya out of the box, is there any must have scripts/addons?

I'm not sure about any scripts (but I'd love to hear if there are any!)
Which version of Maya are you using? I found that the new UV tools in 2015 (The updated unfold tool specifically) actually do it fairly well on thier own.

I just upgraded to 2015. I need to get used to the new unfold, as I was really used to the old unfold method (and that seems kinda bugged in 2015), even though it was a bit tedious.

There has to be someone with a script that layouts the lightmap UVs correctly for Unreal ;-)

No script necessary, the UV Layout tool works pretty well. Copy your diffuse/UV set 0 into a new UV set, and run Layout. I love the new Unfold3d unfold algorithm, but you can always switch back to the legacy version in the Unfold tool settings.

It is decent, but if I am not mistaken lightmap isn't affected by the borders in Unreal, I believe that's what I read on their site - and I cannot get the layout to ignore the border overlapping, so it creates spaces around the border.

Harbinger

True, but that's very minimal. If you're using very low res lightmaps where that extra few pixels of wasted border space is an impact, you could just scale up your UV's a bit after running Layout. Or, go keep an eye on the IPackThat thread
