OctaneRender® 1.025 instancing preview test build

[PeterCGS]

Have made a testbuild, which exports the ICE-Particles as instances/matrixes in a file. This file can loaded in Octane.
The problem is, that the matrixes are written in the ocs-file.
Means, an updated matrix-file isn´t updated because Octane read the matrixes from the ocs.
One solution is, that Octane save every scatter in a single file which is loaded and updated each time the scene is loaded.

It´s also not possible to import multiple meshes via the command line. So i have only one mesh with the shape and the file with the matrixes which i can load into Octane.
A solution is, the same as above.

Another problem is, that Octane selects the mesh node and not the meshgroup or scatter node as default.
With this it´s impossible to make an animation with scattered meshes.

But here a quick test...

Haha! Your crazy! Great work Face! Im sure the instance support will get better pretty fast with a new Octane release

Hi

For Maya users, I Just wrote a little script that can export the .csv file to feed octane's scatter node: Maya to Octane’s scatter node

Seems pretty cool.
Do you want community feedback about this preview?

Some constructive feedback is always welcome.

Assuming you do, these transforms are all very well but how can I visualise which instance I am changing when I edit the list of scatter co-ordinates? and how can I quickly reference a particular one again or talk to another user about the file.
Could we not have an index number to the left for the transforms that can be clicked on to highlight that existing instance temporarily as say vivid pink (perhaps emitting) in the render view, or conversly an instance picker for the view to go to the appropriate numbers in the node inspector? If I want to add an instance to the list can I use a null object or the cursor to interrogate or copy/paste an x,y,z position from the view? Say I had an archviz and I wanted to place a shrub either side of an entry way or hanging flower baskets at specific locations fairly accurately just by mouse selection...

Also can we have the numbers neatly spaced across the field like a spreadsheet with a slight colour cast for the background of the various columns to make it easy on the eye.
Dunno trying to be user friendly here

We realize it's not exactly easy to know which instance is represented by which matrix in the standalone, but the integrated plug-ins should make this much more user friendly.

[RayTracey]

There are two ways to write matrices; column major and row major. Depending on which version you use, the translation component is written in the last row or last column.

Why do you guys even bother with this? Its not that you'll be placing objects around by inputing matrix data by hand.

Why won't we? Sounds like great fun to me. Especuially until Lionel has done his magic on the blender exporter.

That's the spirit

I did another test.
My goal was to beat 1 billion, but it seems i have already been beaten, so i tried to get 1 trillion, to find that I cant, i can only reach around 500 billion, before it crashes, freezes or gpus fail.
I saw a video here it had over a quadrillion on another renderer program, but for now im good with what i got.

I have 1 object that is 5296 polys.
I need 188823 copys to reach 1000000000 (billion)
I reached 5859375 copys............. with a total of 31'031'250'000 polys

face, radiant: these are awesome tests. Always nice to see people pushing Octane's limits. Thanks!

[Slimshader]

Thanks Otoy!
Can't wait to play with this.
Also, thanks tchoa for the mel script to play with as well.

Next and last try.
Seams that all works correct.
Maybe it is possible to use the unused matrix values for color information and then add a checkbox to use the color from the matrix?

I really can't wait for a blender exporter with built in instancing. I've spent the last 2 hours tinkering with manually entering values. The results really don't compare to the magnificence that is being produced.

Awesome!!!!
I didnt even think about using this for fur/carpets. This will really help people doing interiors. No more work arounds.
plus, this pic just looks amazing, The best image I've seen using instances so far.

Lovely image!
