I downloaded the free Trial version of SketchuUp pro and two different tools for it called 3dshome and skimp.

I downloaded a free model of a sleeping bed in the 3d Warehouse and reduced the number of triangles with the Skimp-Tool, to reduce the file size.

As second step i removed all Textures and Materials with the 3ds Home-Tool

I exported the Model without textures and materials and a highly reduced amount of Triangles /Polygons as 3ds file. I reduced the file size by editing the model from over 30 MB to under 5 MB

Although the size of the file (the number of triangles)have been reduced, the materials and textures have been removed, the 3DS model still causes problems in the light calculation. What am I doing wrong ? Do 3DS models not work properly in Dialux?

The sofa consists of very large light and dark triangles.

The second problem I have are rendering errors that I didn't have before. I have already written a post about this.

I was asked to send in the file, which I will probably have to do as I can´t figure out what I'm doing wrong. To do this, however, I first have to shrink the file to a much smaller size.

Maybe someone from the community can help me with this problem.
