Title: Interactive Rendering crashing when using Deformer
Post by: danielsian on 2018-04-11, 01:36:35

Hi guys

I'm struggling to use Interactive Render panel.
It's unstable a lot.

I'm trying to design a nice reflection on a lettering by deforming the front face of each letter with FFD deformer.

It's impossible to manipulate the points when IR is active. It crashes.

Thanks

Cinema 4D R19
Build timestamp: Feb  5 2018 10:42:43
Version: B1  (core 1.7)

EDIT: I've just updated Corona as below.

Build timestamp: Mar 21 2018 10:40:23
Version: B2 daily Mar 21 2018 (core 2 DailyBuild Mar 20 2018)
Cinema version: CINEMA 4D Studio R19.053 S

After spend some timetrying to identify the bug I have a few more details about the problem.

Corona crashes when we use together at least 3 deformers in a specific hierarchy, Projector shader in Reflection channel and SS with 3 subdivisions.

So, to see the crash, just open the scene, start IR and try to turn on all the deformers while IR is working.

I'll leave the scene attached here just in case someone else wants to test.

Hmm runs perfectly for me, R19 + B2.

did you turn on the FFD deformers while rendering with IR?

To get the crash you need to do exactly that.

Yep, I followed your steps. ;)

Yes, I do.

Like I said, I spent a couple of hours trying to understand what is causing the crash, and the behaviour of that is like I've described earlier.

Is the _BugReport.txt handy for you to understand what is happening here?

I've attached it.
