[Unsupported] Blender plugin v1.xx - Code Tweet

[grenzfrequence]

Next i cannot export one object. I get error messages from exporter as follows:

-> NoneType object has no attribute 'OCT_kernel_use'. Is that a bug of the exporter? How can i avoid this bug?

It's not a bug, you don't have a "world" datablock object in the world tab. You probably deleted it, for whatever reason. Create a new one and it will work.

[matej]

About the cube problem; clearly one top edge is shorter than the other, do you have any modifiers on the cube (like displace)?

Post the .blend file

Hey, the error message is solved in xp. It was the missing world datablock. Now i can import almost the whole object. The last problem are the particles. Supports octane blender particles as well? In octane they are not rendered. Then i tried to convert the particles to meshes, but then octane says that the object file cannot be imported and i cannot find out if the memory of the graphic card is the problem. Do you know how to find out it? Exist there one more detailed error message elsewhere, perhaps a log file? This would be important to be able better improve octane i think.

The cube problem is as follows: in ubuntu octane displays the wrong cube, in xp the cube is rendered correctly. Therefore it is a problem in ubuntu. In ubuntu i can address 8 GB because it works in 64bit mode, in xp i only can use 4GB. Therefore i have to find out how to render in ubuntu. Has anybody a solution? Is there somebody else which uses octane with ubuntu 11.04 and blender 2.58?

Greatings, Stephan.

I use Ubuntu 11.04 AMD64, CUDA 4.0, NVIDIA 275.19, Blender 2.58c and Lionel 1.1.0 Exporter without any problems.

@grenzfrequence, just post the .blend file with the problematic cube

Particles are not exported, so you must transform them to mesh object. I think Octane doesn't keep any in depth error logs. Export half of your particles, see memory consumption and do x2, then you'll see if its a memory problem.

I use Octane in Ubuntu 11.04 (ok, used to, now I'm on Mint) with Blender 2.58.1 and did not experience any such strange behavior.

[grenzfrequence]

I posted the blend file and all generated octane stuff in this thread:

viewtopic.php?f=33&t=7330&p=59237#p59237

Perhaps it will help to find out the problem. Many thanks in advanced.

Greatings, Stephan.

One last question for particles: i cannot convert the particles in blender to a mesh, because then the mesh only displays lines, no real object of the particle (here: no real grass). Does it mean that i cannot render particles created in blender? Exist there another way to reach it?

Greatings, Stephan.

@grenzfrequence,

I tried your scenes and there is nothing wrong with them. The .ocs renders a perfect cube. Maybe there is something (terribly) wrong with your driver/CUDA installation on Linux? Reinstall the CUDA toolkit (and maybe also the drivers) and see if it will help.

As for particles, you will have to use a mesh object (or a group of mesh objects) for strand visualization, then make them real and export. The default particle visualization is a strand which is just a 1D line and so useless, unless the renderer knows how to render strands. Model some blades of grass and apply them as particle visualization.

*Bump*

Any chance to get the new 2.49 directlighting GI options and PMC Kernel in the exporter?
Thanks yoyoz for the awesome 2.5x plugin.
