enum ESubUVBoundingVertexCount

Description

BVC_FourVertices

BVC_EightVertices

Remarks

More bounding vertices results in reduced overdraw, but adds more triangle overhead. The eight vertex mode is best used when the SubUV texture has a lot of space to cut out that is not captured by the four vertex version, and when the particles using the texture will be few and large.

Welcome to the new Unreal Engine 4 Documentation site!

We're working on lots of new features including a feedback system so you can tell us how we are doing. It's not quite ready for use in the wild yet, so head over to the Documentation Feedback forum to tell us about this page or call out any issues you are encountering in the meantime.

We'll be sure to let you know when the new system is up and running.
