Chaos Scatter on splines and Vantage

Hi, this has been bothering me for some time and I’d like to share it with you guys,
When Scattering an object on a spline using Chaos scatter, in the 3dsmax, it shows the scatter perfectly, but in Vantage, its different and ends up not following the spline correctly, like it bugs out and does a weird stuff.
Am I doing something wrong?


Thank you.

I think this is a V-Ray for 3dsMax export issue, not a Vantage issue.
If you export the .vrscene and render it with V-Ray Standalone, does it have the same problem ?
It’s logged as VMAX-14887 and the fix will be part of V-Ray 7 for 3ds Max, update 2 (not sure when it’s coming out exactly).

If by standalone you mean rendering the scene using vray-cpu in 3dsmax, the renders shows the scatter perfectly,

If its like external to 3DSmax I don’t know how to do it, but It should be easily replicable in your end, its just a few splines and a box scattered on it.

Thanks for the fast answer!

No, that’s not V-Ray Standalone, that’s the V-Ray for 3dsMax renderer.

If its like external to 3DSmax I don’t know how to do it

From the V-Ray menu in 3dsMax choose “.vrscene exporter” and then click the “Export and Render” button.

but It should be easily replicable in your end, its just a few splines and a box scattered on it.

We have it reproduced as part of VMAX-14887, but without the exact scene, we can never be sure it’s the exact same issue.

Done.


yep, distribution goes all over the place.

black cubes should be sticking to the truss,

Seems to be the same problem.

I was using an array modifier on the spline, worked, but was very slow compared to the scatter, sadly it has this problem too, gotta find another way.

The last image looks completely different though ?

Basically the bug is that if you have multiple disconnected curves in one curve object, the end of one curve gets attached to the beginning of the next.
The work around (until we release the fix in V-Ray 7, update 2) is to have each curve in a separate object and select all of these curve objects in the Scatter node.

If it turns out to be something else, we will need a sample scene in order to reproduce and fix it.

It’s happening the same thing, I have just been fiddling around with the splines and scatter, so the “invisible connections” are in different places, but that’s what it seems to be happening.
The workaround you mention seems to be the logical solution for now, thank you.

Anyways, got another question, is there a way to render an animation in live link, without exporting it to vrayscene? like Scrubbing in 3dsmax and rendering each frame.

I’ve got a Raiclone object animated inside Railclone, and exporting it to VrayScene loses all the animation information, but in Live Link mode, and scrubbing, It works perfectly.

Thank you again.

Yes, use this button from the Vantage toolbar : render_animation.png

Thank you, BTW the original issue got fixed with V-Ray 7, update 2, as you said it would.

Thanks for your help!
