Good evening All!

I have been using Master Zap’s split render script for awhile now, and have to say, it saved me many times in time of desperation..

i had a quick look at the script with my shallow understanding of script, and basically it was utilising blowup regions to split up the render into what ever number you chose.

I have attached the script, all credit to Master Zap (mentalraytips.blogspot.com), for whoever is interested to have a look at.

problem is however..

what i have found is that, say i render the image at 5000x5000, with zero pixel overlap, when i stitche the image, it seems to have some overlaps.  and also whats worse, when i compose 5000x5000 split rendered image with same render that was done in one go, the image don’t seem to match up (i.e, i do my beauty render with split render, my passes straight from max, when i put them on top of each other, they are off by around 5%).

As said, i had a quick look into the script, and it was using blowup render region as its base.

so my question was, does “blowup” render option creat some inaccuracies? like if i were to render 2000x2000 pixel, with 4 of 1000x1000 blowup region renders, will they stitch up perfectly?

will be great if anyone can shine a light on the subject : )

thank you very much in advance : )

I haven’t looked at his script, but are you saving the final gather map and then locking the final gather to that map when doing the final render?  I know if you don’t do that step when network rendering split scanlines in mental ray, you’ll get noticeable lines where the splits are stitched back together.

Have you asked Zap directly via his website?  Seems that would be the sensible approach.  He’s very responsive.

Any news on this one, having the same problem.

We just started using Deadline from Frantic Films.  It can split a render and stitch it back together.  Seems to be working well so far.
