Point Cloud in Block drawn on top of Geometry

[chad1 (Chad)]

I have an issue similar to the one below. If a block contains a point cloud it will cover the geometry in the Rhino workspace when using a ray traced view port. I have numerous files with referenced blocks that all do the same thing. The solution to the previous issue only works if the point cloud is not part of a block.

Point Clouds Cover Geometry in Ray Traced Mode

When rendering in ray trace mode point clouds cover all the rendered geometry. We have tried this in Rhino 6 & 7 and we even went back to Rhino 5 using Ray traced with Neon and we get the same issue. We had generated some views using Rhino 5 before and we are unable to replicate the same view. Is their some settings that need to be set to get the point cloud to show in the correct order. New rendering with issue [image] old rendering worked fine [image]

Hi Chad - this should be fixed in the later service releases - what SR are you running - can you please post the output from the SystemInfo command in Rhino?

Hm, well now I am only getting black viewports in raytraced - something is busted - but a full render looks like what I expect

(later, in-house, sr however)

OK, I do see the problem now in the raytraced vp. If I tumble the view or go into BlockEdit, it sorts it out temporarily… weird, thanks for the report.
