@ tungerz: well done! nice to see you can get something out of it :-)

@ steveps3: the new exporter allows to control all materials of the internal graph from blender (limited to basic drivers such as floattexture/floatimage/image/alphaimage, but for all channels - diffuse/specular/roughness/bump/normal/opacity/emitter). There's little benefit for static images as you should tweak materials inside Octane, not Blender. On the other side, with it you can animate anything from blender, including material type and all parameters from Mesh Preview Environment and Mesh Preview Kernel. It still allow to work the 'old' way, may be just with less accuracy when exporting through MTL (no specular for instance). But once again, this doesn't really matter for static images.

hi yoyoz! thanks for the update!!!i had a grab on it last night but i had not enough time to produce a vid. and yeah the update is very very good and intuitive.
one thing though, if we could add this feature..
- "size" for image environment (could be good if we can control size of background image from blender)
- hot pixel removal
- pre multipied alpha

yeahhhh!! blender exporter is on a go!!!

thanks mate!!
CHOW!!

@ radiant : this is the old framework with new panels and a bunch of new code for managing writes in the OCS. It can be used the same way as before, except that materials exported the 'old' way will have less accuracy than before (new constraints in Blender that prevent the exporter to make real-time corrections on user input in the material panel).

@ r0ug3r : I'll be able to add all options from Preview Imager later, but this is not top priority at the moment. Regarding image size (scale) for environement, my plan is to let the user drive it the same way as material textures (this is why I reversed to default texture panel as the custom one was not compatible with 'World'). However, "Mesh Preview xxx" stuff is accessed a different way than materials so I can do only partial updates on it while I let other parameters unchanged. This means that implementing full texture parameters for the env map will require some efforts on my side and probably won't be available at release time - but definitely in my plans.

Hello crew,
Yoyoz, regarding the new fps, is there options in the works to add a video export ex. xvid or quicktime to be able to use this option?
or do we still have to import all the render's and compose later?

also, I've got another vid cooking i'll post tomorrow.

Cheers,

Andy

Hi Andy,

I'm not aware of any method for using blender's video generator for 'external' png files. It would also mean I develop a method to unsure that we get all frames from Octane, for instance by killing a render that is taking too much time and restarting same frame (this will be done when I implement network render in the exporter but requires some background changes in my framework).

Cheers,
Lionel

Yoyoz octane exporter 1.08
blender 35311
Octane 2.44
Q6600, 4gig memory, 32bit vista, geforce 9600

Alpha channel gave wierd artifacts,this is 2.44 may be something the Refractive crew needs to look in to, dunno.
Some textures didn't seam to give the effect i was looking for, the single static renders came out different than the animation renders, I attached the single frame renders also, I have to look into it to find where I goofed up the textures, but anywho my error, not the exporter :p

10 sec clip at 512 samples/pixel took only, 1day14hours31minutes to render :p
[vimeo]http://www.vimeo.com/20676220[/vimeo]
Just curious, what are the render times are all of you with 4xx's and 5xx's getting on a similar 10 sec clip?

Cheers,

Andy

Yoyoz -> I will send you a mail tomorrow regarding our new XML scene io format plans, it is very important that you plan to switch to it and not use ocs file writing as it won't work, you will end up writing broken ocs files most of the time with undefined behaviour and lots of issues using them with octane, especially without newer releases. (and most of the time you won't know about these problems)

Hi Lionel,

Could you send me a copy of the exporter. 0.93 doesn't seem to work with the latest svn from graphicall.

Cheers

@ steveps3: v1.09 is here since this morning: http://www.refractivesoftware.com/forum ... =32&t=5662

@radiance: I'd be more than happy not writing into the ocs files and will of course switch to another method when available. Please use my email rather than the forum PM for writing me.
