Hi!
We are having issues with Synchro Iray it is showing a hollow surface if we use growth simulation. Does anyone here has the same issue?

I have the same issue when using Iray. I got this reply from Synchro Support: Iray actually does not support cutting plane faces and it's not possible to fill in the gaps created by a cutting plane. The materials are applied to geometry, and where the gaps are, there is no geometry to apply it to. Currently, the only way to implement capping would be to generate a polygon to fill the gap, which obviously is not practical. I'm not even sure if we will fix this either since we would like to transition from Iray to LumenRT eventually.
@Jacqueline Chen is this something you might be able to offer some assistance on? Or hopefully one of the SYNCHRO dev team perhaps? To our knowledge its a limitation of the Iray render, with only 'clunnky' work arounds, such as duplicate objects placed just behind the cutting plane to give the 'illusion' of a closed edge.
Is there an alternative to using growth simulations? Appreciate it might not be ideal.
Splitting the geometry into chunks and creating children activities to drive them (gets heavy on both time and tasks quickly).
I think if you are using the cutting plane tool in Synchro with Iray, you'll see this issue everywhere though. Only solution would be to create your cut in Revit for example and carry this across. It used to be possible to achieve this with a section box, but not sure now.
None of these really help at the scale you need though!
It probably won't make a difference but you could try these settings:
Alternatively you could change the 3D View Properties in the Animation Editor to turn off the Iray view while these growth simulations are active.
Thanks for all the suggestions i will try them all!
