display lightmaps in max?

[dolemite]

hi guys,


Do any of you know a good way to display lightmaps in 3ds max? Like if I have a scene, with many objects and I want to blend the lightmap on top of their textures?


thanks!

set selfillumination to 100%
put diffuse into multiply RGB node, or composite node and mulitply the lightmap over the diffuse.
you may need to increase the output of the lightmap it the bitmap node.

if you want to view this realtime in the max viewport, 3pshader can render lightmaps using the 2nd UV channel http://www.3pointstudios.com/3pointshader_about.shtml

wow thanks!

Great help guys, I kind of racked my brain around this for a while. It's not something I normally have to do.

pern, is there a way to view the map and the diffuse at the same time? WIth the two different UVW channels?

thanks :D

Ayup,

Both "glow" and "shadows" tabs have options for "channel 2".

You'll find these options somewhere in the free version as well.

That should have been "masks" tab, not "shadows" tab.

In the Lite UI it looks like you need the following:
-Occlusion Mask picker
-Use Ambient Occlusion toggle
-Use AmbiOcc 2ndUV toggle (near the bottom of the ui)
