Batch rendering different layers visibility in rhino7?

[Mikele_Schnitman]

its 2022… any batch rendring for Rhino7?
like vray has, or badger (that works only on rhino5)
seems like a must have, an i need it

[nathanletwory (Nathan 'jesterKing' Letwory)]

Maybe _BatchRenderNamedViews will do?

[Mikele_Schnitman]

'BatchRenderNamedViews` doesnt give the option for different layer states.
like if i want to render an object indifferent colors, i would to render one color, change color layer, render again… same in animation.
In veray plugin, the batch render lets you load batch of files, each with different layers on, and selec all the named views and animations to render, and 1 click to render batch them all.

seems simple,but dont see it it exists in rhino render.
this link show something close to what would be needed, as in if named views also kept layer visibility states within them, making 'BatchRenderNamedViews` actully work for multiple colors/states batch renders

Named Views and layer visibility

Hi clement, Thank you for your reply. I have been using the LayerStateManager, and I can control layer visibility but it requires me to switch to the named view, and then switch the layer state. Is there a way to link a layer state to a named view? So when I switch to a different named view it automatically switches the layer state? I don’t know anything about macros right now so if you could clarify how my above question might be done using them I would appreciate it. kmwolf

Is there something similar for snapshots?

Hi Paul,

just tried this in python and it seems to work:

import scriptcontext as sc
import rhinoscriptsyntax as rs


names = sc.doc.Snapshots.Names
for name in names:
    cmd = "-_Snapshots _Restore %s EnterEnd" %name
    rs.Command(cmd)
    rs.Redraw()
    rs.Command("_Render")

[Paul_96 (Paul Wellmer)]

Hey thanks for the effort!
I’m sorry, I don’t have any experience with this! Can I use it as a command or what do I do with it?

@Paul_96
See attached .py
batch_render_snapshots.py (231 Bytes)

to run, put this in a button or assign it to an alias:

! -_RunPythonScript (
"full\path\to\pythonscript.py"
)

[Paul_96 (Paul Wellmer)]

Alright! Thank you very much.
I’ll try it after my vacation:)
Merry Christmas

Hey Gijs,
I apologize for the late reply. I just tried it out now.
This works really well! Thank you for that.
It’s also better to have a copy of your original file that contains the needed snapshots only.
Also, my PC crashes after some time.
It seems to me, that it has something to do with the time the script is running.
E.g.
I have 11 snapshots.
Render 10 samples, 10 seconds each. Fine.
Render 350 samples, 3m20s. Fine.
Render 500 samples, 5m. Pc crashes.

I don’t know what this is about. Since I never used anything like this before or have any clue about programming.

Thanks for the help, I really appreciate the effort on this! If I can help with anything. Let me know!
-Paul

@Paul_96

Render 500 samples, 5m. Pc crashes.

If you say the pc crashes. Does this mean it completely crashes? Or is only Rhino crashing?
Does it crash at the first renderings?
Does it also crash if you render 5 minutes without the script running?

In any case can you type _systeminfo in Rhino and post back the results?

[Paul_96 (Paul Wellmer)]

@Gijs

post back the results

The whole PC froze two times.
It crashes at about nr. 5-7 of 12.
It does not crash when I render without the script.
The last rounds were without problems.

One thing that I can think of is this

Can you try to see if that solves your issue?

So clearing the undo stack at the end of each render. WARNING this clears ALL your undos:

import scriptcontext as sc
import rhinoscriptsyntax as rs


names = sc.doc.Snapshots.Names
for name in names:
    cmd = "-_Snapshots _Restore %s EnterEnd" %name
    rs.Command(cmd)
    rs.Redraw()
    rs.Command("_Render")
    rs.Command("ClearUndo")

@Gijs I’m looking to modify this simple script to export saved snapshots using _ViewCaptureToFile and have each view save to a folder based on the name of the snapshot. Any pointers on achieving this?

import scriptcontext as sc
import rhinoscriptsyntax as rs

names = sc.doc.Snapshots.Names
for name in names:
cmd = “-_Snapshots _Restore %s EnterEnd” %name
rs.Command(cmd)
rs.Redraw()
rs.Command(“_ViewCaptureToFile”)

[Gijs (Gijs de Zwart)]

Note that in your posted scripts there were double quotes that are not supported, only use the straight ones. Furthermore, if the snapshot has spaces in the name, it needs to be encapsulated with “” as well (I see I forgot that in the earlier posted script, and the redraw is not really necessary).

if you copy this to a button it should work:

-Runpythonscript (
import scriptcontext as sc
import rhinoscriptsyntax as rs

names = sc.doc.Snapshots.Names
for name in names:
    cmd = "-_Snapshots _Restore \"%s\" EnterEnd" %name
    rs.Command(cmd)
    rs.Command("_ViewCaptureToFile")
)

[ryan.odom (Ryan M. Odom)]

Thanks @Gijs

When I run this script, I get the View Capture Settings dialogue box for each saved snapshot and it also brings up the save window and offers the default naming convention “ViewCapture01010101” in the file name field.

Is it possible to embed the view capture settings and location to save the files into the script so it will batch them all at once?

[Gijs (Gijs de Zwart)]

Yes that should be possible, for example:

import scriptcontext as sc
import rhinoscriptsyntax as rs

def savesnapshots():
    filepath = rs.BrowseForFolder(message="Select folder to save files")
    if not filepath:
        return
    
    names = sc.doc.Snapshots.Names
    for name in names:
        cmd = "-_Snapshots _Restore \"%s\" EnterEnd" %name
        rs.Command(cmd)
        file = filepath + "\\" + name
        rs.Command("_-ViewCaptureToFile _Width=2000 _Height=1000 \"%s\"" %file)
savesnapshots()
