Swarms become invisible

[corbinyo]

Hi there,

I am encountering issues with the swarms becoming invisible to my camera at certain points when my scene is running. I am animating the swarms and moving them around. Have you dealt with this issue before?

I guess that it disappears because of inaccurate frustum culling. I wonder if it could be resolved by expanding the bounding box.

Thank you, I will try this. The Swarm I am using is the Floating Swarm. I will report back how this goes.

This works, no issues with disappearing anymore - thank you.

Setting are as follows in the "FloatingSwarm.cs" script.:

Graphics.DrawMeshInstancedIndirect( _template.mesh, 0, _material, new Bounds(Vector3.zero, Vector3.one * 10000), _drawArgsBuffer, 0, _props );
