OctaneRender™ Standalone v1.0 beta3.01 [obsolete]

Yes,
it is Kepler build, the load screen confirms that.

With instances you will have lower memory consumption, but the rendering is less efficient.

why?

I understand that this feature is ok for 100.000 instances but for one light and one teapot is not good.

one light (instanced by default) and one teapot less performances.

one plane mesh emitter and one teapot good performances.

You can't move that plane.
It doesn't matter how many lights you have. Amount of instances does.

OK,

today Nvidia got new drivers out,
now my 2,58e version recognizes cuda driver 5.00 and Cuda Runtime Version 4.20,
but still 3.01 Kepler instances version ceases to recognize any Cuda Runtime Version at all,
and says "please make sure you have recent enough..."

Any advices what to do?

Hi Vernon,

What GPU are you using?

Cheers

Hi Chris,

I have Geforce GT650M.
Now with latest Nvidia Drivers also 2,58kepler
has become unstable. I haven´t rolled back to
previous drivers which worked fine, since I hope
I could get the 3.xx to work somehow.

Can anyone please explain me how to use instancing with standalone Octane?

I am about to render few shots for my current project. Its apartment house with a bit of surrounding terrain, and fair share of foliage. The resulting OBJ file is 789 MB big.
Now lets say, i want actually to add grass to the model of the terrain, which is currently impossible cause of insufficient VRAM. Or i would want to add even more trees and shrubs.

How exactly can i do that? Do i have to do something in the modeling app (Max) or is this something to be done within Octane?

If there is a tutorial somewhere, which i missed, my apology. I only checked the 2.58e manual and i see there nothing regarding instancing.


Thanks

obj 780Mo!!!! You manage to import in Octane???
I one day tried to work with a less than 100 and it was already unusable.
Magic from the 3Dmax Octane Plugin? And what is your config to handle such files?

No, i do not own the plugin so far, just standalone octane. My config is in my signature, 24GB of RAM and gtx590. Right now, i am loading the mesh into Octane, it should fit, but 780MB is indeed quite a lot - oh, it says 915MB out of 1371MB of VRAM used now. Add few more textures, lightning, framebuffer - and there is not much more headroom.

Anyway, i see now, there are new things like scatter, geometry group, placement, material map... seeing that, i have certain idea, how could it possibly work (connecting a meshnode of object i like to scatter/clone via that scatter to a material node? or something along the line, or am i completely wrong?), unfortunately its way too many possibilities and i do not have time to play around and look for the right one.

So please, help!

EDIT: i see now, what geometry group does and how you can control rotation/scale of the meshnode via placement. Still no idea, how scatter works - i can see you can load the mesh, assume its the object which i want to be scattered (in my case lets say tree or grass) and clearly you can connect it to a meshnode. But how exactly do you control where on the meshnode should the scattered object appear? I mean, clearly i want the grass to be scattered on the terrain, not on the walls of the building...

EDIT no.2: i found utube tutorial for the placement/geometry group workings, sadly not for scatter (which is probably the one i need to use). Placement seems to be nothing complicated and works pretty straightforward, but there is no way i could manually copy thousand time some object and then move it into desired location via some sliders.

heya.. i cant start it. Message: Could not connect to OctaneLive

What can i do?

You need some kind of exporter that export these positions from your 3D-application into a file you can load into the scatter node. You can check the forum for your 3D application to see if there is anything available.
