Different renders to reassamble later
-
Hey fellow sketchuppers,
I hope this is the correct place to ask.
I'm working on a model of a complete city (several km's long). I made a scene and would like to render the result with V-Ray as base for a big digital painting.
The biggest I can go is about 7500px wide. The final result has to be around 20000px+. Is it possible to render large chunks of the model to reassemble again in Photoshop? If I zoom in, the perspective is different and I can't put them together afterwards. Is there a plugin that is able to zoom in without altering the perspective? I could render the chunks with a bit overlapping and then paste them together in Photoshop.
Sketchup: 7.1
V-Ray: 1.05Thx ahead, it would be such a help!

Why is this the biggest? You run out of memory?
Have you tried rendering to VrImage instead of the VFB? -
Wow, thx for the quick respond. I didn't know there was such a thing.
I followed the tutorial where I had to half my resolution. I tested it on 5000px and then final render to 10000px. That worked perfectly!
But when I tested it on 10000px for a 20000px render, I got another Bugsplat.I just tested it with a single bitmap (a drawing of the roads and water) on the correct size, there weren't any modelled buildings on it yet. I choose 'default.visopt'. It crashed a few seconds after I pressed the render button. Is that a memory issue?

which tutorial?

Open Task Manager and monitor the memory usage of SU while you render.

I hope that was what you suggested

Yes. that's the one. And you still experience crashes? hmm...
as mentioned before - check the memory usage of SU while you render. -
It crashed the moment I press the renderbutton, it doesn't even show a peek in the memory usage.
It's weird though, I have the new i7 processor, Rampage II extreme MoBo and 12GB ram. Even thought V-ray is limited by Sketchup's 32bit, I shouldn't get short on memory right? Am I missing things?
-
Yes you can run out of memory. Not for your system, but for what SU can address.
But it is odd that it crashes upon hitting Render. Sounds like there is a different issue. Might want to contact ASGVis support...

I've had that happen a few times with the old version of Vray, it was always caused by a texture that Vray didn't like. 99 percent of the time it was a gif or png that I got from the web then did some processing in PS and saved as a jpeg to use as a texture, instant crash.

And is there a facility in VRAY for su in any version that i can render a part of my view in 1 hr....save it and then render the remaining portion another day ........then save my session......then render the remaining part another day??? I mean just like Download Accelerator plus gives us the facility of broken downloading is there a facility for broken downloading that we are able to resume from the last session??

Not quite as pause and resume - but in the latest you have Render region. I guess you could use that along with saving IR and LC maps. But I've not done that myself - very awkward method.
Why not just let the computer run the night? -

Step by step to render to VrImage: http://software.asgvis.com/index.php?option=com_content&task=view&id=16&Itemid=55
Normally you render with the V-Ray Frame Buffer (VFB). (The window that normally opens up when you click Render.)
But that makes V-Ray store all info in your RAM. That means you will eventually run out of memory with large scenes or rendering in large resolutions.When you render to VrImage you render directly to a file, you don't use the VFB. Because V-Ray outputs directly to file it free up more memory so you can render larger scenes and in higher resolutions.
So when you experience that VfSU crashes on your due to running out of memory, render to VrImage.

I just wanted to point out that thomthom, although awesome, is not a magical wizard. He knows the answers to the questions, because he reads the documentation for the product. I suggest everyone else does the same prior to discussing basic features that are covered in manuals and getting started tutorials. I would imagine it would be nearly impossible to accomplish anything in v-ray at all if you never read the basic documentation and a few tutorials on a variety of subjects. V-Ray is a tricky program with a steep learning curve, it's easy to get lost, that's why that stuff is out there to help you guys. Check it out, you might be surprised what you learn!

i see.. so how to assemble them?? i mean...on the website it said vrimage to exr convertor.. how to get the jpeg output
pal?? -
You must use the VrImage to .exr tool found on ASGVis website, then open the .exr in an image editor and resave in the format you want.
