I still don't understand the way corona saves files

[Maybejensen]

I created a thread a couple of years ago, complaining about the way Corona saves final rendered images. But it still makes absolutely no sense whatsoever.
As far as I understand, we're supposed to check "Save File" in the common dialog in Render output, and find a location,  this way it will save all render elements along with what's previewed in the frame buffer.
However, after I've completed my final render, I turn off the "Save File" checkmark, and it is still saving test renders in the same location because saving is turned on in the render elements.
When I uncheck "Save file" how comeliterally doesn't do that?
Currently, when I uncheck it, it is still saving all my render elements, which often leads to overwriting final renderings.
Every other engine V-ray for example doesn't do this, and have implemented their own save file dialog.
What workflow are you all using to combat this?

Hi,

Yes this is annoying I know. I face the same issue using Corona 10, but I didn't know other rendering engines don't produce this issue.
Actually I thought it was a 3ds Max related bug, and not Corona related, but maybe I'm wrong here I don't know.
I found a workaround for this: I use a small script that enables me to delete the path where render elements are saved so that, after completing a render with 'Save file' unchecked, render elements don't overwrite any files that have been rendered previously.

I am going to ask the developer their permission, and if they agree, I'll post the script here.

Hey Tom, I'm glad I'm not the only one frustrated. You can DM me the link if you'd like

This is how it works in 3dsmax, always been this way, not related to Corona specifically.

Hey Pokoy, I'm aware. However many render engines circumvent this by creating their own save file workflow.
Maybe we could get something that resembles the one in V-ray.

Wouldn't it be better if Autodesk would fix this issue once and for all, so that every third-party renderer developer wouldn't need to re-invent the wheel? Maybe it's worth to go to Autodesk forum and tell them about that?

Yep, it is annoying, not sure why this still exists.

To combat this I usually run this script (attached down below, this was the wrong script), it deletes the render elements path. Wont affect anything in future since when you click 'save' it will output the render elements again. You just have to keep an eye on it since when those render element paths come back you have to delete them again (run the script) before your next render.

Hi,

I heard back from the developer, he's ok for me to post it, so here it is:


macroScript Archimi_NETTOYAGE
category:"Archimi"
    toolTip:"Nettoyage"
    buttonText:"NET"
(
    try destroyDialog ::ArchimiCLEANER catch()

    rollout ArchimiICLEANER ("Archimi CLEANER ") width:200
(
    Group ""(
    button btn_EffacerChemin "Effacer chemin de l'image de sortie " width:180 height:30
    )

    Group "Chemins RenderElements"
        (
            button btn_ELements01 "Assigner un chemin + PNG" width:180 height:30
            button btn_ELements02 "Effacer chemin existant" width:180 height:30
        )


    on btn_EffacerChemin pressed do (
    rendOutputFilename = ""
    renderSceneDialog.update()
    --messagebox "Fichier de sortie effacé"
                    )

    on btn_ELements01 pressed do (
    local RE= maxOps.GetCurRenderElementMgr()
    local REcount=re.NumRenderElements()
    local thescenename=getFilenameFile maxfilename
        if REcount != 0 then (
                        thepath= try(getsavepath caption:"thetitle" initialdir:maxfilepath)catch()
                        for i=0 to REcount-1 do
                        (    local ElementName= (RE.GetRenderElement i).elementname
                            local thefile= thepath+"\"+thescenename+" - "+ElementName+".png"
                            RE.setRenderElementFilename i thefile
                        )
                    ) else
                    (    messagebox "Your RenderElements is empty :)" )
    )

    on btn_ELements02 pressed do (
    local RE= maxOps.GetCurRenderElementMgr()
    local REcount=re.NumRenderElements()
        if REcount != 0 then (
                        local thefile=""
                        for i=0 to REcount-1 do
                        (    RE.setRenderElementFilename i thefile
                        )
                ) else
                    (    messagebox "Your RenderElements is empty :)" )
    )

)
createDialog ArchimiICLEANER
)

I see it's written in french but it's pretty straight forward to translate.

You can do the same thing in one line of code:

Looks like this isnt working with the latest version of Corona, Probably best to go with Toms solution. Although Tom it looks like there is something missing in that script, can you post it into a code block or attach the original .ms file?

[Tom]

Hi,

Sure. All I have is the .mcr file:

[James Vella]

Thanks Tom.

Oh my bad, this actually is the script that clears the corona output paths, I was looking at the wrong file.

Code: [Select]

re = maxOps.GetCurRenderElementMgr()
for i = 0 to re.NumRenderElements()  do re.SetRenderElementFilename i ""
