System Information
Operating system: Windows 10 Home 64 bit
Graphics card: NVIDIA GeForce GTX 1080
Blender Version
Broken: 2.80 Beta c6cbcf83d015
Short description of error
- a mesh object consisting of a single vertex (in my example named "Vertex") has an array modifier (3 instances) on it
- it has another object (in my example a UV sphere named "Sphere") as its only child object
- instancing (per vert) is activated on the "Vertex" object
- as expected, the sphere is instanced three times
- as soon as render mode "Rendered" is activated (in Cycles), rendering seems to be stuck in a loop, rendering sample 1 over and over again
- also, only the first and last instance show up in the render, the "middle" instance(s) is/are missing
- happens for CPU and GPU alike, but only in Cycles, not in Eevee
- when the array modifier is applied, the error goes away
Exact steps for others to reproduce the error
- please open the attached file and switch display method to "Rendered"
