Assembly: Microsoft.Xna.Framework.Graphics (in microsoft.xna.framework.graphics.dll)
A bitmask value controlling write enables for the samples. Each bit in this mask, starting at the least-significant bit, controls modification of one of the samples in a multisample render target. This render state has no effect when rendering to a single sample buffer.
This render state enables use of a multisample buffer as an accumulation buffer, doing multipass rendering of geometry where each pass updates a subset of samples.
Given n multisamples and k-enabled samples, the resulting intensity of the rendered image should be k/n. Each component RGB of every pixel is factored by k/n.
