Help please 3ds/udk modular pieces

longhornfan25

ok so i've made some modular pieces, and now i'm starting to build the building . but once i start to stack them weather i be side by side or on top of each other you can see the outlines of the shapes. i've spent ALL day making sure that every diffuse normal and specular map tiles. and it still happens...

anyone know what im doing wrong??

Thanks,Michael

UDK (if two objects are outlined the same color there the same modular piece)

This looks too modular. As in, broken into too many pieces in a non-necessary situation. It's a flat wall with windows cut into it.

However, did you setup 2nd channel light map UVs? And if you did, did you keep them on an accurate pixel grid (in max) of their respective resolution (in UDK)? If not, the lightmaps' edges bleed causing errors when baked.

yeah i know ,ha im working on that right now.

and no.. i haven't done a 2nd channel light map. that probably the problem

if you know of any tuts for that please send them this way

Thanks so much

nvm i figured it out

Props for figuring it out. How about posting a solution so that others could benefit?

The vertex normals probably weren't contiguous.

Yea, I second you telling us what you did...I had a hell of a time with this a while back.

Sorting out the lightmap would be job one. Then bake it with the normals on the edges matching. One way to do this is to weld a tile on either side when baking and in the UV space move those extra pieces outside of the renderable space. That way your normals behave as if they are connected and everything shades well.

This thread covers some of the same problems.

But if I had to guess, it was the lightmap bleeding that caused his issue.

more detailed info on my last post. The fix noone seems to know about yet <shrug>
