Vray animation loading the scene per every frame

[fattonyrends]

Hi All,

 

I was curious if there is a way how to set up the animation in Vray so it is loading all the instances and assets only ones. Since i have quite detailed and a little heavy scene in take about 10 sec to load the instances and such. In 300 frames it makes quite a amount of time.

 

Thank you for suggestions,

Stefan

Unfortunately there is not a way. By the sound of it you have just the one machine to render on........50 extra hours is a lot when you only have one machine. But if you think about it, 3dsmax has to figure out what it needs to render for each frame, which actually saves you time and probably RAM because if it loaded the entire file at the start, that might take up all the RAM you have and the file would crash when it renders.

 

I think your only solution is to have more machines rendering. Maybe try a render farm online. There are many.

Hello,

 

Thanks for tips.

We have actually small farm inhouse. it is i think 120 physical cores, so this is not a problem. The problem is also that is loading the textures and instances that are not animated and is why i dont get why it is like this.

Okay, that's helpful then.

 

What do you mean by not animated? Do you mean they are not visible to the camera? I don't know your rendering setup, but you have to take in to account that although something might not be directly visible in the frame, it might be visible in a reflection, so max still loads it in. So something like a tree leaf, which might have a glossy reflection value, and potentially thousands of leaves at different angles, if one leaf needs to reflect an object that is not visible, VRay loads it in.

 

If you hide objects that aren't visible, they won't be loaded so perhaps you can hide some things to speed it up?

Sorry i might not explain it right

 

Any object for example a vrayproxy, even if visible or not visible to camera is being uploaded from server into the scene. transforming vertices and loading instances and loading bitmaps is happening in every frame. there is no reason for this, this information should be caches somewhere already. the plaster texture of the wall has no reason to be uploaded 240 times when it is exactly the same texture for every frame.

 

I understand about the reflections and all, even GI only is making a difference but still. I just think i have something disabled because this looks like huge drag when having a bigger scene. And also i dont recall to be happening to me in other files like this.
