(Daily Build 2019-09-20) & Corona 4 - MB and Interactive Rendering

[Nejc Kilar]

Hello peeps,

Something seems to be wrong with the Motion Blur and the Interactive Renderer.

If you turn on MB and then tweak the corona camera tag settings it stops working and you need to disable and then enable it again in the render settings to update - Otherwise it just doesn't do MB anymore. It literally ignores the fact that MB is turned on.

Seems like a crucial bug that is also present in Corona 4 Hotfix 1. Would be cool to consider another hotfix I guess?

IDK, got a scene to share?
It's working fine, if Sky is turned off ;)

PS
Note: mBlur is not working with deformers.

Can't provide you with a scene but here is a video example :) Totally reproducible in R21 with v5 dailies.

No deformers involved, just a camera with an align to spline tag that makes it go full circle (align to spline aligns to a circle for a turntable like movement)

Alright, figured out whats causing it. Its the animation of the camera using the "align to spline" tag.

Basically I have animated the position of the camera through the above mentioned tag and the IR is apparently getting all sorts of confused with it. Definitely needs a fix :)
