<![CDATA[Why is Skimp increasing model size, not reducing it ?]]>Hi,

I am testing Skimp. I downloaded 10MB model of a sofa into a clean SketchUp file, then used a Simplify Selection tool from Skimp to decrease the size to 85%, then saved the file under new name. The size of the new file increased to 15.5MB.

It has been happening with other models too, after simplifying them with Skimp. Am I doing something incorrectly or is Skimp faulty?

In one case you selected the Photo Real Materials which added an environment image. These are rather large image files which will bloat the SketchUp model file size. Deleting the environment image reduced the file size of your "skimped" .skp by more than half. In the other, you added a material with maps for metal, roughness, and normal. Those maps added to the file size. Removing those maps again reduced the .skp file size by more than half of your "skimped" .skp.

After cleaning up the model files it is clear that SKIMP is doing what it is meant to do.
