Greetings.
I have in issue with exporting models from blender to 3ds files. Seems that I`m loosing normals.
I have a program that uses DirecX. Im loading 3d models in it in .X files. Models are made in 2 programs - SketchUp and Blender, after compliting I export models to .3DS and after that I
m using Microsoft Windows ConvertX Utility (conv3ds) to make an .X from .3DS.
After loading .Xs to program it seems that models from Blender loose their normals. I can
t use light sources at all. Models just ignore them. Files from SketchUP are correct, and work with light sources ok. I have checked .X files in text editor and yes - .X that was made from Blender .3DS misses any info about normals. It`s info ends after material data.
Ive copy-pasted normals data from SketchUP->3DS->X file and mine broken mesh begin to work with light too, but all faces were messed up cause of different vertex data, so just copy-paste don
t work properly.
Also Ive exported Blender Mesh to .OBJ and checked it in text editor - normal data (vn
s) was there.
I have searched google a lot but haven`t found any info about it. Any help will be appreciated.
