Hello everybody, i try to ask in english...  ???
How can we affect the same material to many objects ? Or can we duplicate a material ?
Thank a lot !

Well you have to apply one material to all objects you wanna have the same material applied to already in your 3d software. Then they will all have the same material you apply to them in Lumion. But at the moment it is not possible to share custom made materials in different scenes or on different imported objects.

Tell us what you want exactly and maybe we can advise. You could actually add the same material to everything in Lumion but that would screw up UV maps (unless you have the exact same size of materials everywhere like 512x512 pixels).

True however that best is to start with this in the modelling app.

Bon, en français alors c'est trop difficile en anglais, désolé ! :-D

L'idée c'est de pouvoir affecter le même matériau à plusieurs objets similaires dont seul le mapping diffère. Par exemple, j'ai des poutres en bois du même type, mais qui ont plusieurs directions de veinage. Je voudrais pouvoir affecter le même matériau à tous ces objets, puis ensuite pouvoir individuellement traiter leur mapping. Une autre idée consisterait à pouvoir dupliquer les matériaux, car dès que l'un est réglé et que l'on souhaite en refaire un à l'identique, il faut alors manuellement reprendre tous les réglages...
Un peu de souplesse dans ce sens serait fort agréable, je ne vais pas au stade du projet faire un seul objet qui sera carrelé ou boisé, je dois pouvoir les dissocier même si le matériau au départ est le même... Est-ce assez clair ?

Merci les chefs ! :)

...The idea is to assign the same material to several similar objects which only the mapping is different. For example, I have wooden beams of the same type but have different directions of veining. I wish I could assign the same material to all these objects, and then to individually treat their mapping. Another idea would be to duplicate the materials as soon as one is set and we want to make another identical, one must then take all the settings manually ...
Some flexibility in this regard would be very nice, I'm not at the design stage to a single object to be tiled or wood, I have to separate them even if the starting material is the same ... Is that clear enough?...

Well, if the above Google Translate is correct, you can have two choices here:

Apply the certain wood material to your objects (with grain going in the required direction). Now whenever you change something in your modelling application (like switch materials) and update the model in Lumion, the UV mapping (grain direction) will be maintained.

In Lumion, you can assign the same Lumion material to several imported materials actually. If you set the scale to zero, all UV mapping data will also be retained.

I also wish that we could save our custom materials so we would not have to tweak them with the same settings manually when several objects with the same material are imported. Actually, beside some of the terrain wishes, this is my main wish. I know that people will now kill me but for me, this would (have) be(en) more important than interior lighting :)

m having a problem with glass material. it only reflects the sky and clouds. what can I do to make it reflect what's around it?

Fahad Hanif.  Reflection in glass are of the Lumion cube.
This video shows you how reflections in the glass work. 


They are not like real world reflections but rather optimized reflections for speed.
Old school techniques running in harmony inside the world of Lumion.

Hope this helps   :)
