When will the demo be usable with Cinema 4D?

[keithkml]

Hi, I'm using OS X 10.6 and I am really impressed by Octane. However, currently there seems to be no way to use the demo with my 3D program, Cinema 4D 11.5.

OBJ Export: Octane will import this, but without any textures. Yuck!

Riptide: Octane crashes whenever I import stuff I exported from C4d using the Riptide plugin - even when it's just a simple cube (see attachment). Apparently this will be fixed in the next release, whenever that will be, according to http://www.refractivesoftware.com/forum ... =25&t=1055 (i'm using beta2.2)

C4D Octane Plugin: well apparently this is available to customers, but it really needs to be on the public download page IMO! Other 3d software developers (RealFlow, etc) publish these plugins for their demo users.

So in short, I'd love to evaluate Octane for my projects, and I'm wondering when this will be possible. Thanks!

Hi,

You are probably using the wrong export settings in riptide.
Post a screenshot of your export settings so we can see what you used.

The plugins are not available yet to demo users as they are not %100 documented yet.

Thanks for your prompt response!!

BTW, there are no screenshots on the "OBJ export settings" thread for Riptide - just someone asking for help because they get (presumably) the same crash - http://www.refractivesoftware.com/forum ... s&start=40

Here are my settings!

Hi keithkml,
You should try to export without n-gons. Try to uncheck the "Export Ngons" in the second screenshot.
I'm not totaly sure but i think it's one possible reason of your crash.

[keithkml]

Thanks for the tip, but unfortunately it still crashes with N-gons disabled. It even crashes when I disable the "export faces" section completely. In fact, it still crashes when I disable everything in the export tab.

[keithkml]

I also just tried converting the line endings from UNIX to Windows, I heard that might have to do with it. And it still crashes!

Hi,

Do the octane demos work ? Have you tried our demosuite ?
You can download it on our downloads page.

Maybe it's a driver issue.

Yes, the demo scenes work great. And the crash isn't in driver code, it appears to be in GUI code:

Looking at the obj files Riptide produce vs the ones Cinema 4D natively produces, I see a huge difference in the "vt" and "f" lines, which describe the texture vertices and faces:

Cinema 4D:

These are interesting numbers Riptide generates:
4294967297 = 0x100000001
140733193388035 = 0x7fff00000003

In fact it looks like all the numbers are just small #'s with junk in the first 32 bits.

Looks like we've found our problem!

A little note - despite these messed up files, Cinema4D and Riptide both import them correctly. (Though perhaps they shouldn't

For now I'm going to write a python script that fixes up the files before importing into Octane...

Why not just get a license and use the c4D plugin we have ?
