Issue: Arnold render empty or a part of the scene

[Sunny_Suppy]

Arnold render empty or a part of the scene. This issue is serious because you just often only find it out along render sequense. So hard to find an alternative when the scene is huge with many completed - lookDev asset/cloners. I also find this bug in older versions. Hope you can fix it. Thanks

This is project, render sequense video :

Can someone at least feedback to me about this issue ? Thanks in advance!

I would start by providing a log.

[Sunny_Suppy]

Thank for feedback. I don't really understand you word but if you mean I provide a log for you by press Shift + F10, then sorry there is no log. It's written nothing in the log. That 's just an nature happening issue, without any notify. I did provide a link of project above. You can download and check it.

The scene renders fine if you change the Instance Mode of the Cloner to Instance or Render Instance.

Not sure yet what's wrong with the Multi-Instance mode, need to investigate further.

[peter.horvath6V6K3]

So the issue in Multi-Instance mode is a bug in the plugin, which is triggered by the Plain effector. The effector sets the scale of the source geometries to 0, which is not handled correctly by the plugin and all instances are exported with a zero scale. It will be fixed in the next c4dtoa release.

Meanwhile a workaround could be to change the Scale of the Plain Effector from -1 to -0.99 for instance. Or switch to Render Instance mode as I mentioned above.

[Sunny_Suppy]

Excellent found. This is just a small test. Since C4D have multi-instance mode, C4D user never use instance or render-instance in large scene. Because it will destroy the computer. Actually render-instance mode is useless nowaday. Thank you for finding the error !

Fixed in C4DtoA 4.0.3.
