Maxwell Render | Official public forum

Happens to me few times - after setting many MXS references (inside ArchiCAD, as instances), I render my scene and everything is ok.
When I Stop render and Resume strange thing happens in my render — almost all instances turn to Ghosts . I presume that they automatically switch to Hide from camera option
but still drop shadow n the scene.
Any of You experienced something like this, huh?



after Resume rendering:

For me all instanced mxs-references completely disappered lately after i stopped and resumed a render directly from the maxwell render window. Only one copy of each mxs-reference was rendered.
Scene exported from sketchup.
(resuming a network render works fine)

Probably it is the same case. As it it visible on my renders - some of the instances are still alive probably these are first mxs which I've placed there (don't remember).

What happens if you:

-close the Maxwell window
- reopen it and reload your MXS
- click Start, Maxwell will see there is already an MXI with that name and ask if you want to resume
- click resume

My workflow is ArchiCAD -> Maxwell Render. As I understand - try your steps with Maxwell Studio?

ahh... now i think i restarted the render with a different resolution - so, no resume but complete restart. So this would make sense... if you resume the render and it gets merged with the first run the objects are transparent as seen in your example.

i had problem like that when i modify the original scene than i resume render
so i make copy of the scene to avoid that

No, just close Maxwell.exe first, before resuming. I assumed that you render, then click stop, then hit resume again? If not, ignore my suggestion

As I try to play back the sequence - these two hints could help. I click scattering for simulens, and probably I've started without closing Maxwell.
It is WIP so probably I'll re-render it two or more times,I'll be careful then.

I've reported that here:

Solution is to close Maxwell window and do resume after reopening it.

Thx everyone for help. Did not change anything this time and after Maxwell restart I resume render with all instances

I never resume a render since it causes all sort of bugs (like yours...).
If I need to send something before the render is finished (like a draft for the meantime) I just take the images and leave the render running.

What kind of other bugs?

You have to remember that if you change anything in your MXS between resumes, it will of course look weird when you resume the render.

I use resume all the time...

the most annoying: the render notes the SL it reached, not the DESIRED SL. so you click "render" and say that, yes, you wish to resume... see that all is loaded and voxelization started, and go home. and than find in the morning, that the render finished successfully because it stayed at the same SL...
I also had a problem that resuming a tmp scene failed.

That's just bad workflow procedure. You should always save out the MXS and MXI for later resuming. I would never try to resume some temp mxi for an important job.

Also, I have found that getting used to using the Network Wizard for all final render jobs, even if only on one computer, is a good idea, because it forces you to keep track of and organize your MXS and MXI files.
