Scale UVW Dividing by 2

Submitted by TwilightZoney on Fri, 2015-11-06 22:22

I need to make this 2nd UV channel to be scaled down divided by two. Since when exported to the engine it scales up and multiplies by 2. I need to rebake GI for the light map so I need it divided by two to work on all selected nodes.

Any help with this?

Basically from that picture I need the whole thing to be divided down by two to fit in the checker box thats how it gets multiplied up.

Need this since I only have the engine files that I exported and no longer have my source files.

I've tried a few ways already

I've tried a few ways already but none seem to get them to be accurate.

$oldfortress_wall_3.modifiers[#unwrap_uvw].unwrap2.ScaleSelectedXY 0.5 0.5 [0.02192,0.977479,0]

Tried doing this but the position is offcenter and doesn't match up correctly. Not sure what I"m doing wrong.

with your pic, I think after you've scaled it down by half, you have to offset by half the UV space which is 0.5 up in V as you can see in
my illustration pic. You can also over write channel 1 as well but I made the default new channel as 2.
