Real time link，Forest is very slow

[q976431]

I use forest pack to build plants, and there are millions of plants in my scene.
When I need to adjust the parameters of forest or paint plants with forest's mask brush.
I use pause rendering, and 3dsmax becomes very slow. I may have to wait for dozens of seconds to respond. If I disconnect the real-time link at this time. Then everything goes smoothly.
3dsmax seems to be transmitting all the time. Even if I have turned on forest's manual refresh function or pause rendering function, it can't prevent it from being transmitted to vantage in real time.
What should I do. I don't want to disconnect real-time rendering often

Maybe when you turn on the manual update of the forest or the pause rendering of vantage, Do not transmit data in real time?

HI q976431,

You should experience similar behavior if you have a V-Ray IPR running. This is expected as thousands of geometries are being updated and exported. We will try and see if something can be optimized in such a case.

I'm using vantage's live link
It should run the IPR function of vraygpu. But I open the manual refresh of forest. Or use vantage's pause rendering. I can't stop it from transmitting data in real time.
In my opinion, after these functions are pressed, the transfer of forest data to vantage should be temporarily stopped Wait until I finish adjusting the forest and cancel "pause rendering",Or press the update button of forest, or restore the automatic update of forest, and then transfer the data.
Do I understand wrong?

Now, unless I disconnect the real-time link. Otherwise, it is difficult for me to edit the parameters of forest or paint with brush when there are a large number of forest objects. 3dsmax becomes very slow, especially when painting with a brush. It is almost impossible to complete.
In addition, when pressing the real-time link button,
If Vantage is not closed, you can ask the user whether you need to keep the current parameters of vantage.
Now, when the real-time link is reopened after breaking the real-time link, all parameters will be initialized and need to be imported repeatedly Vantage file to load parameters into vantage

I had another similar situation today, this time on thousands of vehicles with animation.
And it also leads to a serious problem. This is my new request:

Vray IPR slows down the speed of dragging the timeline. This may not be vantage's problem
But in my opinion, Vray GPU is no longer involved in picture rendering. If I use vantage's pause rendering, I should temporarily stop the scene data transmission of 3dsmax. Isn't it? Maybe Vray GPU is not optimized for this. Even if it has not performed any rendering and calculation. It still thought it was doing rendering calculations and was not taken over by vantage.

It is not rendering data to the VFB but it is still exporting data with every change and that slows the whole experience.

No, pausing Vantage only stops the rendering inside it so that not to utilize maximum GPU usage but V-Ray is still transferring data though not seen in the viewport or in the VFB.

We will try and see if something can be optimized or implemented in such a case.

Thanks for your answer, maybe my thinking is wrong

But You should take a look at my other request first, this question leads me to another new problem. It has even affected my render results
