problems exporting model to 3dstudiomax - Polyloop

tartino · 1st May 2006, 02:17

I have some problems with models I made with hexagon and exported as 3ds or obj.
When I import them in 3d studio max7 some polygons looks empty in scene and in renderings. The empty faces looks correctly only viewing them from other side.
It seems to interest only sides of objects made in hexagon using simmetry cloning.
The others 3d applications as carrara or cinema4d have not problems with that models. Only 3dstudiomax.

Any idea to solve this problem?

thanks

It sounds like the 3dsMax importer is flipping the normals of some faces. Simply use the function in Max to unify the normals of the object (I'm not sure what this might be since I don't use 3ds, but I'm sure it'll have something which can do this).

Have a look at the Hex2 Help---pages 289 and onwards.

Yes ,you can unify normals in hxn2 before exporting.

there is operations which can cause normals to be flipped ( some welding tasks)
working without showing backfaces may help at the end

thanks for answers

If you means the normals options while exporting in hexagon as obj, i tried but seems not working.
The same playing with 3dstudio max7 normals unify options while importing obj.

thanks in advance

No that' not it.. I'm talking about the utility "orient normals" ,it's a bit err..sofisticated ,there is more than one way for doing (with space bar or not )
I'll try to show in details

thanks very much i found them in hexagon2.
I flipped all wrong normals.

However it seems a bug that it flips inside all normals of an object duplicated with simmetry and welded.
It's a noise to check normals of simmetry clones while building. But it's a nightmare to do it when the work is finished and the clones are a lot.
