OTOY Forums

Hello dear Octane Team,

I have a problem with the import of my architectural project. I watched all tutorials and their were really good understandable.
But i have a problem with the import of my object. If I import it out of Archicad as a obj. file it doesnt fits with octane and the software shut down.
But if I import it in Cinema 4D and export it then as a obj. file it works well till i want to "shader"(dont know if its rly the right technical word for it) my 1000 elements, like walls windows constructions furniture etc.
If i choose a Object like a furniture, Octane takes the whole Building like it would be one big unit.
So, how i can seperate all the diffrent object layers like in the tutorial chess example?

Sry for my english but I hope you will fortunately understand what I mean.

with best regards

Hi Ruby

I just know that Archicad creates good meshes by exporting them in 3DS-Fileformat (choose "separates objects by material" in the Archicad export options).

I guess if you export it first to a 3DS-Format an import this to C4D and export it from there to an OBJ-Format it could work.


Kind regards
Alain

PS. I would choose the word "materialize" for "shader", but I'm not an english pro as well

I think i found the problem.
I had too complex layernames in my file. I exported the file to 3dsmax and converted it then as a obj. file with the option to recreate simple layernames.
Now it works rly good

Hi guys,

I would not use .3ds file format for transfering models as it's a 16bit index format, so you can only have maximum 65536 triangles.
OBJ is the best interchange format.

from my expiriance its best to do
Arrchicad - BLENDER (texturing, etc) - Octane render
i export as a 3ds from archicad...but i will try with obj like radiance say!

Sry Radiance but it doesnt works to export the file directly from Archicad to Octane as a .obj
Yes we have the solution to save it as a object file and the save options for object files in Archicad are not rly difficult so i tried all prospects but it doesnt work.
Only if i save it as a 3dsmax file and convert it then from blender or 3dsmax back to a object file it seems to work.

Hi,

If it works like that then use that technique i'd say.
however, if you plan on doing larger models you might want to split it into multiple 3ds files, and export to OBJ from your modeling app after adding the 3ds files together again as there is a 65K triangle limit for 3ds.

What settings do I have to use when importing the model from Archicad to Blender? I keep getting an error message about not being able to import the model.
