Hi,

Is it possible to render a picture in parts.

This because a client wants a picture in a very high resolution and I'm not sure my computer have enough ram to render this in one part.

The render region function doesn't looks to be the solution.
Shift lens doesn't seem to be usefull.
The -hd command line options doesn't seems to work at all :-S.




Here I read something about a function in Rhino.

Is there something like that also for Mw studio?

Help!!!


Thanks

Can you not just set your cameras up to render the different regions so that they overlap a little and then composite and stitch in photoshop and crop appropriately?

not ideal... advice.. buy more ram.. it's cheap these days..

[naikku]

now this is true.
i just wrote an email to a local store, said I want 4gb extra and xp64. 32bit os wont do.
that way I should have 6gb+64bit os ---> 12500x4000 renders are possible.
ram is really cheap now. 4gb for ~60euro.

edit: i have done some 5000x2000 renders now, but the client wants 125cm banner.

The -HD command is not available anymore, it was simply not efficient and since the memory optimisations the mxi file size and memory usage of Maxwell has decreased. For high resolutions you need an OS that can adress more than 2GB per application. How big do you want to render? You can render it smaller and blow it up in post.

Hi People!!,

Thanks for you're advices!!
I'm only afraid that more ram isn't a solution for me. At the moment I've got a 32 bit XP machine. The maximum amount of ram = 4 Gb, and that's precisely what I've got at the moment.

I'm working at a big (bureaucratic) company so if I want to have a machine with a 64 bit OS and 64 Gb Ram I'm afraid the gentlemen wearing nice looking suite's and having grey hair aren't going to approve that.

I'm afraid the only possibility to render that image would be in parts

If someone has I different solution or a great work flow to do this I'm very curious.

Hi Mihai,

The client wants to have a big publicity board with the new situation of an interior. The board will be something like 2x1 m with 120 dpi so the resolution would be around 9000x7000 px. I think if I can get a resolution of 6000x4500 px with Maxwell it would be good enough for post processing in PS.
The model will be complicated so I don't think I will get this resolution in Maxwell.

Hi Louis,

If you disable vignetting or set it to zero, you should be able to render out quadrants using film shift. It will take some trial and error though.

Hi Frances,

That sounds very interesting.

Only, I can't find that function in Maxwell Studio. Can you explain this function a little more.

Thanks in advance.

[Frances]

I'm sorry Louis, the maxwell term for it is Shift Lens. The function should be covered in the user manual.

To use it for your purpose, set your camera up as usual and then for each quadrant you want to render, you shift the lens 50% in each direction. Be sure that vignetting is set to zero (that may need to be done from MXCL). Then you piece together the final image in a photo editor.

I hope this helps you get your job out!

...vignetting is set to zero (that may need to be done from MXCL)

Not any more since 1.7. That can be done now pre-render too.

[Asmithey]

Maybe try using a rendering service. Ranch computing has machines with 8 gigs of ram. It will cost money but you can get the job done. If his suits are really nice, maybe he can afford it with some persuasion.

Hi Frances,

I tried your tip on a small model and for now it works!!! Tomorrow I gonna try that with a big model.

Looks like the shift lens option has a bug in Studio 1.7. The border of the camera stays on the same location wile I shift the lens. If I hit render, the camera moved to the right position.

Thanks!!

Can you use a tile camera with your modelling software? - render the individual tiles and join them. If so it would be a precise way of rendering a large image.

Hi Becco,

Unfortunately, MicroStation doesn't have something like that. I also prefer Maxwell Studio above MicroStation to setup my camera.

Thanks.
