autocad_3dsmax problem

[massi84]

hi to all, I expose you my problem: I imported the model created with autocad 2012 in 3ds max and once rendered, as you see in the photo, some elements do not have the textures in scale like all others; the circled wall has the same layer of all other walls. You know what the problem is? Thank you.

what kind of mapping did you use? planar, or cubic?
is the floor on the same layer as the front one?

hello thanks for the answer; I simply applied the same material "stucco" to the walls and to the highlighted wall and the floors are on different layers.
Now I'll put you another test:
create 2 cubes on autocad 100*100 cm, the unit of measurement on autocad is cm;
to that of the left I hang a material and to that of the right not;
the amount on 3ds and I apply to both the material "ceramic/tile 3in square - earth cooked";
I make the render and the left one has the texture not in scale while the right one is.
is there a logical explanation or is it a software error?

... I simply applied the same material "stucco" to the walls and to the pointed wall...

with this you mean you didn't specify any type of mapping, did you stick the material and stop?

... and the floors are on different layers.

being on different layers when it amounts them are two separate objects or have two different volumes and extensions, this affects how the material is distributed on individual objects

I don't know the technical explanation of this anomaly, but consider that you don't usually care about dwg already mapped in 3d studio, because it is much better to do it directly there.

thanks for the help, I solved by changing the mapping in cubica. Bye!
