Culling geometry with camera volumes in Python script

In cases where you know from which angles an asset will be viewed, you can use that information to optimize the assets accordingly. For example, side scene geometry in the level that's only going to be seen from the playing field. Rather the building assets custom for that case, you could just use what you got and optimize it through cameras scattered in the player area. You can instruct Simplygon to cull anything fully occluded, but the visibility information can also be guide the reducer and the material caster to keep more where the geometry is most visible.

Creating a physics mesh with Simplygon

When creating physics meshes, it's typically a good idea to optimize the original heavily, to make calculations cheaper. You would also want to keep material information in the optimized object, in order to spawn appropriate effects, play correct sounds etc. Combining the vertex color caster and remeshing is a great starting point to achieve super-simple geometry that checks the boxes for good physics meshes.

Batching assets using headless Maya

Simplygon has a native plug-in within Maya that can handle exporting and importing assets. This is not only useful when you are working within the Maya UI, but can also come in handy if you want to batch process many assets and use the built-in functionality in Maya. In this post we will sho how you can set up a simple batch script that runs headless in Maya.

Visibility sphere

Using a visibility sphere can be a great way to save some polygons on assets that are not going to visible from all angles. In this article we will go through how you can use the SetCustomSphereCameraPath function in Simplygon to take away unnecessary polygons.

Volumetric culling

If you, like most others, are using kit bashing workflows when you are designing your levels volumetric culling can be really useful. This method will help you get rid of internal geometry, without affecting the exterior, nor require you to generate new materials. Apply it to assets that are built up from several small pieces and you will get rid of a lot of internal geometry, that's just hogging performance. In this post we will look deeper into this method.

Geometry culling overview

In the Simplygon SDK you can find a range of options in the area of geometry culling. You can cull geometry volumetrically, use custom cameras, distribute cameras along a spherical surface, use occluders and clipping geometry. All these options can be combined in different manners to achieve the results that you are looking for. In a series of posts we'll go through the different options you have at your disposal. We'll explain how you use them and in what cases the different options comes into play.

Simple hollow shell script

In this post we will show you how to create a simple python script that generates a hollow shell. This can help you to optimize kitbashed content that typically is riddled with internal geometry which causes all kinds of performance hits. The resulting hollow shell will have all its internal geometry removed, while the object collection looks exactly the same from the outside. Perfect as a final step to clean up your creation and make it game ready.
