Sometimes scene geometry has too much details and exported scenes become large and take long time to load. To address this you can reduce the number of details in some meshes or in the whole scene, using the geometry optimization tool.
Let’s start with an Owlet model which is quite heavy. Drag it into the scene, then select it and click Tools -> Optimize Geometry… item in the menu. You will see a wireframe mesh on the selected object and the tool starts pre-processing the mesh:
Once the mesh is pre-processed you can see it optimized to some extent:
You can now adjust the optimization parameters to get the best balance between the number of triangles and the visual appearance of the shape.
There are two parameters you can configure:
As both parameters affect the shape, Koru uses the one that gives more optimized result.
Here we limited the number of vertices by 1000 and got quite a low-poly model:
Find the proper balance using these parameters then click OK to commit the changes.
Sometimes mesh optimization can lead to artifacts in texture mapping. If your shape has texture, especially a wrapped one - it is a good idea to double-check the optimized version for artifacts. You can always undo the optimization and try less agressive parameters or avoid the optimization completely.
