Material assignment in Lumion

Hi 3d peeps,

I'm just starting with Lumion, and i've some noobish question. I've looking around and havn't seen the answer to this. (maybe i've missed it, in this case sorry for the double post)

I've create my modeling in 3ds max, exported the file in .DAE file
The first problem is that I can import in lumion standard demo, but not in ultimate demo (sp2.b5)
anyway...it work on first release

the picture here :


As you can see, each material groups are separated by color, to help the material assignment in Lumion.

problem is :
if I group (in 3ds max) all objects to have one object by color, i've got a crash when importing in Lumion.
Import is ok only when I import the whole in separated object.

This is a minor issue, but my question is :
could it be possible to assign same material for differents objects in Lumion ?
when i select imported object , I click on "+" to create my material and assin to the selected part (one arch). But if i select another part (a second arch), i have to click on "+" again to add another material and i can't use existing material.
I think i don't have to create same material again, but I don't know how to do.

Someone could help me ?  :-D


I hope you would excuse my stinky english

Strike the last post, even in SP2 b7, this material issue is still beyond me. If you could save the custom material, then you could just click on it and bam. But you have to use the default one and modify it everytime... this can get very tedious if you have a lot of parts and can't put things in groups before hand.

Any suggestions or solutions?

Export as 3ds or FBX out of your modeling program and let us know your results.

Do not use the "Object Color" tab next to the object name to assign materials to your instanced objects. Prior to exporting, press M to open the Material Editor in 3DS Max and apply separate Standard materials to the objects.

When importing the objects, Lumion automatically collapses objects that share the same material into 1 surface, so that you only need to apply a Lumion material once to that surface.

Let us know if that helps.

@Morten
this is the point!
in my 3dsmax scene, this is not a basic object color.
Each color fit to a material slot, with a standard shader.
However, the link between surfaces doesn't work in Lumion, that's my problem. (thats why I asked for the multi-assign, an other way to do same things)

Another way could be to attach all objects in max to export only one object by material, but import doesn't work.. |:(

maybe 'cause i have first demo of Lumion, i'm on the way to d/l the free sp2b7, maybe it could help

@Crhoades
I think there is too many poly for a .3ds export, but i'll try in Fbx and say you how it react.

@Dreamcube017
thanks for trying, i'm dowloading sp2b7, maybe as you it can't help, but it couldn't be worst.

halleluia brothers !

problem solved (until i've another one)

I have install the sp2b7 version but in fact... i think the problem is elsewhere. I run with 3ds max 2011 which have a .DAE collada exporter in native.
I assimilated this one with the free OpenCollada on this site, huge mistake.

It seems that the native one doesn't work very well and create some bugs on importing, like a bad edge loop setting...and some minor things. It works with not too complicate objects, and creates bugs with huge ones.
In the sp2b5, it directly create a "ghost" object.

So i've run the free opencollada and it work fine with the 2b7. I try to import the file with collapsed objects, by material, and it's ok.
I have to try if it works with non collapsed objects on same material slot to see if Lumion recognize the material ID.

I hope Lumion can import huge polycount object now, optimized ofc but still huge ...

Anyway, thanks all for your comments, attempts and help.
Be sure that you'll see me again on this forum with some other problems haha
:)
