C4D Application Error when rendering a still

[harries88]

Heya all,

I'm getting an Application Error crash whenever I kick my render off to the picture viewer. It'll think it over for about two minutes and then crash before it finishes sorting the Geometry. It seems to render fine to the live viewer and I can save a PNG out from there as it's just a still I need but I did want to get some passes from it as well so that I can fiddle in AE. Screenshot attached.

Am pretty new to 3D and in particular Octane so am willing to bet the mesh I've modeled isn't optimised all that well or I've done something else noobish and its maxed out my specs. I'm running a single 980 ti. I should be getting a new setup later this week with two 1080ti's that I wanna network to the 980 so hopefully that'll solve this but any help you can give would be really helpful.

Thanks all

First you need to know why this happen. Maybe the reason is high amount ot triangles or some shaders. You have to test and find what's causing, could you?

[harries88]

Triangles shouldn't be an issue as I was fairly strict on keeping everything to quads, I'll start troubleshooting the textures now and see if any one thing in particular is panicking it.

Do you have subdivision objects? But you may be correct because i see just 600k triangles.

Ha! Ah OK, do I take it you're being sarcastic? As 600K would seem like a lot...

Not sure how that happened. Everything was modeled with quads and then subdivided.

Anywho I seem to have isolated the problem to the front section, To try and get a bit of detail in there I plugged a couple of Octane Mix materials into one another, and they each have displacements on them. Could that be it do you know?

[aoktar]

That's not much, honestly very low amount of triangles. Problem should be a different thing. But you have to find that if you don't share a full scene.
Only thing i'll say that LV vs. PV is not working same by default. PV is set to "Auto detect" option and LV is set to "All movable" option. This may make some difference on exported geometry structures.

Ah brilliant cheers,

It seems to be just too much memory required to send all the different bits of GEO to render.

I've switched different elements of the front section on and off and it isn't any one of them in particular that is tripping it up but seems to rather be the collection of the lot. It pushes the 'black screen' portion of the render past 1.45 which seems to make it crash. I'll try and optimise that front bit and then it should go through OK.

Thanks a lot for your help.

If your geometry is static they will be collected to one mesh with "Auto detect". This can cause out-of-memory on export to PV. You can simply switch to "All movable" to test it

[harries88]

Ah brilliant, that seems to have cracked it. Cheers!
