Broken: version: 2.80 (sub 53), branch: blender2.7, commit date: 2019-03-31 21:52, hash: rBb936d7b16c62
Worked: N/A (new feature)
Short description of error
Plugging the value output of the dot-product node results in a crash if the vectors are from two different objects. This bug seems to occur for any two vectors from different objects, on any vector math operation. I tried using the Geometry node, too, which resulted in a crash.
Not sure if this is a bug or merely an incomplete feature.
Exact steps for others to reproduce the error
From the .blend file attached, simply plug the vector math node into the output (The bug will also occur if you use an emission shader, but it's unnecessary).
I want to add: this is a great feature, and I'm so happy to see it coming to EEVEE! I imagine that, coupled with animationn nodes, EEVEE will be the renderer of choice for VFX artists. Also, as an NPR artist, it's an invaluable tool for me! I want to say a big thank-you to Clément Foucault for all his hard work on EEVEE.
