Render a Point cloud in grayscale

[Pooya448]

Hi there, I am new to pytorch3d, I read the tutorial on rendering a pointcloud with rgb colors, but

I have a a set of points with a probability between 0 and 1 for each point,
Is there a way to use the renderer to render this poin tcloud into a grayscale image with probabilities for each point representing the gray color channel values?
