Forest Lite / FP Pflow distribution - Motion Blur issue
« Last post by Flyro on Today at 12:33:23 AM »
Hello everyone,
I'm a student and we use Forest Pack Pro at school. I can't post in the Forest Pro section because the licenses are own by my school though..
I am making this post because we are facing a troubling issue with Forest Pack in Particle Flow distribution mode.
The motion blur generated by Forest Pack pflow distribution mode seems inaccurate. There is way too much motion blur on the mesh scattered for the movement made in the 3d scene by the particles (picture 1).

If the motion blur was correct, it should have been a very subtle blur in this 3d scene.

The only way I found to "fix" this issue is to disable the motion blur or to make the particles static. We can't reduce the motion blur on the Forest Pack by tweaking Vray Properties motion blur duration value, it doesn't affect the motion blur in the render.
This motion blur issue is present in every 3D scene I make, I think that the issue is related to the way the motion blur is calculated in particle flow distribution mode in Forest Pack.
You can try it by making a 3D scene with some particles moving, and scatter object on those paticles with FP Pflow distribution mode. Make another object which move at the same speed as your particles. You'll observe that your motion blur for your FP in your camera will be incorrect.

Is this problem well known and is there some solution to fix the motion blur?

Thank you so much for your help!

Forest Pro (*) / Re: ForestSet + Clusters ?

If this could not be solved technically, it would be useful to at least have some script that adds objects from ForestSet to the Geometry sheet. Something like Explode.

First, let me apologize for the late reply. Of course, the RailClone plug-in can handle the vegetation easily and it can also deform it if needed. If you prefer using the Forest Pack plug-in, as you've pointed out, the Effects feature can be used to assign the corresponding item (.geomID) based on the position on the path (.distPathPos). Please find attached a sample scene (distPathPosSampleScene.max) demonstrating this possible approach. Alternatively, you can switch to the Custom Edit mode and select the first and last item manually. I hope that helps.

Best regards,

Hi,

Thank you very much for your feedback. I'm afraid that's not supported at the moment, and it's hard to say if that could be implemented somehow, but we'll check what can be done in future versions. When it's used in the Geometry list, a random item is assigned.

Best regards,

Forest Pro (*) / ForestSet + Clusters ?
« Last post by ZO6039 on March 27, 2024, 07:23:53 AM »
Is it possible to use clusters for distribution if I use ForestSet? If I use only one ForestSet in geometry list than clusters distribution doesn't work for ForestSet members. Let say I added different types of grass to ForestSet and use it as geometry for ForestPack. It means I cannot use clusters. This makes ForestSet pretty much useless. Can we get clusters working with ForestSet members as well?

RailClone Pro (*) / Re: Scripts for RailClone
« Last post by Mannii RC on March 25, 2024, 10:49:41 AM »
I have an issue with Railclone Tools and maxscript.

Let say I run

Code: [Select]
Railclone_Pro.global.Instantiate 2 "aaa" false false false true
It does what it suppose to by instantiating railclone, but somehow 3Ds Max movement goes weird.
Even if I try to reset to empty file after that, I create a box, I try to move that box, it'll go really far.

All I can do is to close that Max and reopen to gain the normal movement again. It's like the Instantiate process somehow trigger something with the axis.
This however, does not happen with the Instantiate button in Railclone Tools. Only happens when I try to run the Instantiate via maxscript.

Another question.
In the doc, (https://docs.itoosoft.com/railclone/railclone-tools)

Code: [Select]
Railclone_Pro.global.Instantiate (1)mode (2)layerName (3)autoDelete (4)separatedMeshes (5)forceInstances 
and then

Code: [Select]
Example: Railclone_Pro.global.Instantiate (1)0 (2)"railclone_instances" (3)true (4)true (5)false (6)true
How come there's an extra argument needed? What does it do exactly?

Hi,

Please, tell us what is your other account, and we'll try to unify both.
For security reasons, i suggest you send us the information from the support form.

Thanks,

Even if the object I'm working is vegetation?
What I'm trying to accomplish here is scattering hedges along splines, but there is a specific object that needs to be used at the beguiling otherwise will look wrong
I tried to find something on the effects but unfortunately It's too advanced for my knowledge.
