The same frame is output

[q976431]

I have a scene that contains 175 frames.
This scene is very slow, especially when dragging the timeline.
When I use real-time link for output, I find that it sometimes renders the same frame repeatedly, but the name is a new frame. For example, when rendering 00005 frame, it is the same as 00004. However, the name has been successfully output to 00005
Is it because my scene switches the timeline slowly, so I render without successfully switching the key frames?

I use "1" for output. I haven't tried "2". Are their underlying logic the same?
If the same, I may not have to try "2" again

[q976431]

At the same time. I sent some frames with different output results. He seemed more vague. I didn't add the special effect of lens blur to my scene.

The two pictures in the attachment are two adjacent frames. But their clarity and color are different

I caught an error.
How can I send the video to you?
Please provide me with your email address
This question is indeed as I said
3dsmax Drag timeline is slow. Even if it has switched keyframes. However, in vantage, the picture is not refreshed in time. At this time, Vantage has rendered the next frame, but the Rendered image is not updated. The video I recorded can clearly illustrate this point.
The scene has not been released yet. I can't upload YouTube Please provide a mailbox. So that I can see the wrong video by sending this.


:
My scene contains thousands of animated vehicles. Maybe they caused 3dsmax to get stuck after dragging the timeline. However, this problem is normal after disconnecting the real-time link. Pressing pause rendering also won't stop 3dsmax from slowing down

Let me explain what I caught
Also explain why you rendered the same picture.
Because my 3dsmax drags the timeline very slowly, and vantage updates the new picture slowly.
So when vantage starts rendering, its picture is still rendering the previous frame. If you haven't switched to the next frame when the current frame is rendered. Then I will get the same rendering result.
If it updates the picture when the current frame is about to be completed. Then I will get a very fuzzy rendering result of the next frame.
Maybe my expression is not clear enough. But I believe you will know what I mean after watching the video
The rendering progress of Vantage is out of sync with the time when vantage receives a new frame! This is the main reason for the problem

Maybe you should add conditional judgment
After vantage actually receives the data and refreshes the view, it can render instead of judging whether the 3dsmax timeline has been moved.
Of course, the most important thing may be to solve the problem of delay in rendering when 3dsmax timeline and vantage appear

I have sent it to your colleagues through email some time ago

Could you give us the support ticket number you received in reply to your email, so we can check the status?

edit: never mind, you've sent it to Alexander

Yes, I sent it to Alexander
Then I have a suggestion about the convenience of vantage.
Now, if I disconnect the real-time link and re link the real-time link, it will initialize all parameters, and I have to load them repeatedly Get parameter configuration from vantage file.
You can add a pop-up window to ask me whether to use the previous parameters;
Or judge if it is the last real-time link Max file, you can directly use the current vantage parameters instead of initializing all vantage parameters;
Because I just disconnect the real-time link, and then re link the real-time link after some model operations. The current situation leads me to constantly reload in this process Get parameters from vantage file. It's very inconvenient.
I use google translate, maybe my description is not clear.

Hi q976431,

Now, if I disconnect the real-time link and re link the real-time link, it will initialize all parameters, and I have to load them repeatedly

Which parameters are you modifying in Vantage that you wish to retain when reconnecting?

Best regards,
Aleander

Starting live link is the same as loading a scene file (we have no way of knowing that it's reconnecting the same scene). We reset settings when loading a scene in order to have consistent behavior. Otherwise your scene could look different depending on what was opened previously. You could use "Edit->Save Scene Settings As Default", though this would affect other scenes as well, so it depends on how specific your settings are.

good
I can temporarily set the default value when making this scene to avoid repeated loading. This is a method

Is it possible to pop up a window to ask the user whether to use the parameters of the current vantage when it is detected that it is not the default value during real-time link? Instead of going back to the default

Hi q976431,

Aleander

Maybe when relinking in real time, after detecting that vantage is not the default scene parameter, you can pop up a window to ask the user whether to keep all the parameters, because after I disconnect the link, I make some scenes and then continue relinking.
At the same time, why should I repeatedly disconnect the real-time link, just as I previously fed back about the slow data exchange from Vray to vantage. It makes me have to disconnect the real-time link when I do many operations. Otherwise, my 3dsmax will become very slow and even need to wait 30 seconds to switch keyframes

Otherwise. In fact, I am very happy to keep the real-time link for any operation.
This will make me better enjoy the fun of real-time rendering. Unfortunately, in the current situation, in some large scenes, the experience is not very good

What parameters are animated in your scene, such that vray would have to update them when you switch the frame? Lots of instances? Changing geometries?

We should investigate if vray for 3dsmax does something that can be significantly optimized. It would be useful if you can share a scene that we can use to measure which parts of the exporter code run slowly.

I will ask my colleagues to prepare a scene for me. It may take some time，If he's ready. How can I send the scene file to you? Please give me an email address
But now I can describe this type of scenario first
It has a large number of models, just architectural models The max file is about 2GB. But the real-time link is very smooth at this time.
I found it through my test.

I try to describe it clearly through Google translation
1：
When I use forest to plant a large area, such as grassland, when the number reaches millions of grass, 3dsmax dragging the key frame will be very slow (but the area generated by millions of grass is not very large)
I'm not sure that when I drag the timeline, Vray will update and re instantiate forest?They don't seem to be changing parameters, nor are they animated objects. I just drag the timeline
2：
Then there are a large number of vehicles with animation. I generate vehicles through splines for trajectory movement. I test when the scene reaches thousands of vehicles, such as 7000 and 8000 vehicles.They automatically advance in the direction of the spline with the timeline.Then, during the real-time link, 3dsmax drags the timeline very slowly, When the final sequence is rendered, vantage begins to have the problem that I described earlier is not synchronized with 3dsmax data, resulting in abnormal rendering sequence


However, these problems described above completely disappear after disconnecting the real-time link, and my scene can preview and drag the timeline very quickly.

Could you try switching keyframes with V-Ray GPU IPR? Is it as slow as when using Vantage?

Yes, Alexander suggested that I try dragging under V-Ray GPU IPR.
It's also slow
After the test, this is likely to be a problem with V-Ray GPU IPR.
