olivhan Posted September 27, 2011 Share Posted September 27, 2011 hi forum! usually i am rendering small little images, kind of previews and reduced graphics, no photorealistic stuff... now i have to render an image of a building that will be reproduced pretty big, and the resolution must be 8000 x 8000 pixels. I started my machine (iMac i7, 8GBRam, 16 GB free HDD) yesterday evening, and it crashed after 8 hours of work and had nearly 70% of the job well done... there was just this error message, that the rhinoceros stopped his work... does anyone has a hin of what went wrong? thanks in advance!

Dave Buckley Posted September 27, 2011 Share Posted September 27, 2011 pre calculate your gi solution then render in sections and stitch manually in photoshop afterwards. providing you don't have access to network rendering that is Link to comment Share on other sites More sharing options...
olivhan Posted September 27, 2011 Author Share Posted September 27, 2011 hi dave! thanks for the quick response! that sounds quite logic, but i cannot find in vray where to calculate my gi settings and the option to render in sections... i don´t have access to network rendering Link to comment Share on other sites More sharing options...
Dave Buckley Posted September 27, 2011 Share Posted September 27, 2011 http://www.spot3d.com/vray/help/150SP1/tutorials_imap1.htm try that, with regards to the rendering in sections, once the maps are calculated you could just render 4 regions using normal region rendering techniques. I wasn't thinking of any special button as such, although you could look into distributed rendering/strip rendering? Link to comment Share on other sites More sharing options...
olivhan Posted September 28, 2011 Author Share Posted September 28, 2011 I guess I understood the procedure... but now I´ve got some more questions... -how can I calculate the IRmap, without rendering? The rendering causes the crash... -after calculating the map, how can I tell Rhino or vRay to calculate the picture from 0,0 to i.e 4000,4000px? (see Image below) Stripe rendering is not implemeted in vRay for Rhino. The distributed Rendering does not offer me any other opinion either, I only have one machine running vRay...

Dave Buckley Posted September 28, 2011 Share Posted September 28, 2011 I'm not sure about Rhino, but in VRay that I use with Max, in your global switches rollout there is a tickbox for 'Don't Render Final Image' when just calculating the GI, also in your GI rollouts you have the options for single frame, from file etc. With regards the split rendering, just draw a regionthat roughly covers a quarter, render, save, next quarter, render save, next quarter, render, save etc. Just make sure all your regions overlap so you can line up the four renders in photoshop? clunky but should work Link to comment Share on other sites More sharing options...
