OctaneRender® 1.025 instancing preview test build

can the plugin suport images sequece?

It is important to animation!!

hi, i've posted a couple of xpresso utility in the Cinema 4D section for playing with the scatter node.
it's not a very comfortable solution but helps in waiting for a more professional one

It would be nice to support special characters in names like test_instance_cube1.mtl for mtl-files.
The obj-file loads fine, but the mtl-file isn´t load/used.
For scenes with multiple files it is usefull to seperate about the filename which file is what...

Importing MTL files and image files with spaces or special characters works. If you use non-ASCII characters Octane assumes your files are encoded as UTF-8. Are you getting an error importing such files?

using a two input geometry node with a simple ground plane as first obj and an other object used as instance scattered on the second input , I got white strips on the ground plane on the render of the geometry node, whilst the render of the ground is correct with the obj mesh node of the plane selected.



Octane freeze confirmed here too, with Nvidia driver 301.42.

Do you also get these lines with a less complicated object in the scatter node?

The freeze is a bug in Octane, we will fix it.

Wow, great work, though despite skimming through whole thread, i still have no idea, how this works

Simple question> Once its ready, i mean completely, will i be able to locate the position of instances manually (or using some scattering plugin like Advanced Painter) within the modelling app (3ds max), then just export it using whatever the new format will be, import it into standalone Octane and these instances will be just there with no further need to deal with all these sliders, scatter nodes, placement nodes and other stuff? Obviously, Octane would recognise those instances as instances, not copies. I imagined it to work somehow like this, i really like me Octane simple seeing people talking about matrices and excel files makes me dizzy

Yes, that is the plan. Once we develop an exporter file format, the exporters can export instances directly.

Why a geometry group can´t render from the command line?
Have build this setup:

rendertarget.jpg

The scene has the name test.
Exported mesh is test.obj.
After starting Octane, the rendertarget node is used with the -t command, but only the test.obj is rendered, before the placement.
Commandline is:
-m test.obj -r "G:\Octane\ProjectA\test.obj" --cam-up-x -0.153499 --cam-up-y 0.902506 --cam-up-z -0.402395 --cam-target-x -0.0449646 --cam-target-y -0.0413809 --cam-target-z -0.0114845 --cam-pos-x 0.113271 --cam-pos-y 0.170481 --cam-pos-z 0.403327 --cam-fov 53.638 --cam-aperture 0.01 --cam-focaldepth 5 --imager-exposure 1 "G:\Octane\ProjectA\test.ocs" -t "RenderTarget"

I know, camera and imager aren´t used in my Octane setup, but it should render the same scene as when i select the RenderTarget by hand...

Using both the -m and the -t option will render the given mesh node with the settings from the given rendertarget. So in your command line it will render the mesh node "test.obj" with the settings in "RenderTarget". Loading a new OBJ file in "test.obj" and then rendering the scatter node is not possible from the command line at the moment. We will add this to our TODO list.

I would have to test again : I don't remember. I see your response only today and I have not done instance tests recently. I am not on my workstation currently.

For anyone can help me to understand!!!

I can not understand why in rhinoceros get one thing, and in Octane render it I get a completely different.
Any idea?
I used Grasshopper to define my matrices

Thank a lot

[Daniel79]

this is the matrix that i used to traslation the box on the same green square of the green box:

[0.00, 0.00, 1.00, 5.00, 0.00, 1, 0.00, 2.00, 1.00, 0.00, 0.00, -5.00]

Is this wrong?

[Daniel79]

If I write the matrix as explained roeland (1 0 0 0 1 0 tx ty tz 0 0 1), ie:
1 0 0 5 0 1 0 2 0 0 1 5
this is the result, it would be correct if looked from below upwards ...
how do I fix it?
