Hello, are DR and progressive mode compatible? Are Progressive mode and save to image file (vrimg) compatible? When trying to used that on a render farm service the project got stacked. Thanks Farm Name: Rebus

It’s a bug; we are working on this right now and we should have a fix fairly soon. In the meantime, writing to an OpenEXR file instead should work fine (provided that “memory frame buffer” is enabled). Best regards, Vlado

Bump. Having an issue with this - I have a scene set up with Progressive mode, with V-Ray raw image file checked and a proper absolute path to an EXR specified. With Generate Preview OFF. I still got a full-res frame buffer while rendering - is this right? The EXR was NOT generated during renderi…

Would it be possible to run the same test on a very simple scene? I just did that and it worked fine here with 3.00.07. There was an error about “cannot write output image files” but the file was written successfully.

I will try on a simple scene when I can - on a very tight deadline, hence the cry for help! I have not checked the vraylog to see if there’s any error happening but I don’t think there is. Just nothing being written at all. Unless there’s a temp file location somewhere on C that I could check?

I’ve just tried this on a massively simplified version of the same max scene with only 1 object, the HDRI and same settings, and it’s not writing any file during rendering - only after i hit Cancel. Then it writes the file. Because I never specified the time limit or noise limit for PR it just kept…

I get an error: Cannot write output image file “…” (with the file name there).

ok so it works fine if i use vrimg. it does NOT work with EXR. so this is the issue. regardless of 32 bit checked or not, by the way. edit. when i hit cancel, interestingly it still says "Cannot write output file “… .vrimg”. but it actually does.

question - at what time/passes intervals is the vrimage updated? Every minute? 5 mins? 100 passes? just ran a PR for about 5 mins and it didn’t update the file once during rendering, only at start and when i hit cancel.

Oh and Generate preview seems to make no difference to anything. I get my VFB window and the render is shown regardless of if it’s on or off.

I have emailed you a zip/max file Svetlozar - hopefully we can find the issue!
