You should be able to confirm this yourself with your script (delete everything else from the scene). This would appear to be a bug in DAZStudio, although perhaps there is some other override which we are missing.

The documentation for getPreviewControl() states:
Code: Select all
The property controlling whether or not the node is drawn in the viewport.

Hi Paul,

You are right. I completely missed that. I was so busy looking at the UltraScatter created nodes that I forgot to check the getPreviewControl on the manually created instance group node. Like you said it is returning true. I will explore further. I think there might be some other setting that is telling IRAY to ignore the proxy nodes and render only the required nodes. Will explore and update if I find anything.

Hi Paul,

I think I have figured it out. For each of the DzInstanceGroupNode call getTarget(). That will return the target node for the instance. On that target node object call isVisibileInRender (). If that returns false, don't use it for creating the instances.

I verified the UltraScattered cube Proxies has the target set as UltraScattered cube proxy which has the Visible In Render set to false. For the cube instances the target is the cube and its Visible In Render is set to true.

So I think you need to check the target of the instance group and check its visibility in the render (IsVisibleInRender()). If the target is not visible in the render, don't create the scatter nodes and if it is visible in the render create the scatter nodes.

//Sample script
var TargetNode = CurrentDazInstanceGroupNode.getTarget();
var IsTargetVisibleInRender = false;

if(TargetNode) //Check for TargetNode being NULL
IsTargetVisibleInRender=TargetNode.isVisibileInRender();

if(IsTargetVisibleInRender == true)
CreateOctaneScatterInstances(CurrentDazInstanceGroupNode);

Hope this helps.

Regards,
Rajib

Thanks Rajib - I think you have got it! Below is a test build for you to try. It is built with Octane 3.05, and also closes the viewport when you load a new scene (trying to fix the other issue you reported - however this does not resolve the problem).

Just tested this build and it appears to have solved the placement issue. Cheers.

Excellent. Thanks for you help tracking down the problem.

Thanks Paul

! It is working. For the first time able to load scene with pre-built Ultra Scatter instances

! Now can start to render more complex scenes and starting creating scenes using the UltraScatter and see how it goes. Thanks again for the fast turn around.

: Just a sample scene loading perfectly now.

I am sorry to resurrect this old thread, but it appears that the Ultrascatter issue is not quite resolved yet. While it works fine on the first run of Ultrascatter (and on a small number of instances), it does not if I try to run Ultrascatter again on an object that was just scattered (or if I scatter a large number of instances, such as 8,000). It just throws the error; "an error occurred while reading the file, see the log for more details." If I then save the DUF file and re-open it, Daz Studio crashes every time.
And as noted, DS crashes when I try to scatter a larger number of instances.

Both of these issue are repeatable in the simplest way possible: Create a plane and scatter a sphere on it.

(I'm on Octane 3.6.4.34)

It appears that all the errors are coming from Ultrascatter, not Octane in the above log.

Paul,
However, what about when I open a scene file with instanced objects and DS crashes (never running the Ultrascatter script)? When I disable Octane and re-open the same scene file, DS does not crash. This seems to suggest that Ultrascatter is not part of the problem, since the script was never run.

Can you send me a .duf file which crashes when you load it pls?

Thanks

Paul,
Please check your PM. (Note, I could not post it here, since it is a project I am working on).

Let me know what you are able to find out. Thanks,
