Hi... here my spec : My spec C4d r16.038 / Octane 2.22.2 test 3 / gtx titan black ed / Geforce gtx 680 / mac OSX yosemite last built
I 've attached a jpg of my scene... i put three spline that warp around a vineyard... there role is to illuminate the trunk while they climb
around it... i attached a octane blackbody emission texture to get the illumination.

But once i render the scene, i can see the light through the trunk.. you'll see it on the attached file

Thank you for helping if ti's a bug.. maybe i just did it the wrong way ..

my trunk material is a glossy one i attached a jpeg ..

Have you read manuals, faqs?
Or watched latest tutorials?
Really tired to answer same questions like that "is it bug?". Please try to understand plugin how works. There is only a few tricky part to need understand.

ok sorry

as i'm a dyslexic it's a little bit difficult for me to find something on manual.. and i can't find any tutorial on it, i understand that you're tired, but could you just point me at the direction where to look at...
thank you

Sorry to hear. Shortly you can assign octane object tag to each emissive object and keep renderer on "resend only updated". Also please watch these:

thank you very much.. i've tried a lot of thing by myself, and the artefact seems to disappear when i deactivate the displacement on my trunk share.. i'll let you know.. thank you very much for your patience ...

Nice to hear that you have figured. If it's disabled on displacement that's a limitation of octane engine. Not a bug. Displacement is very limited to imagetexture and some conditions. But these are very own to core engine and i have to answer for these limitations. This can make me a little jumpy because it's not a matter of my work.

Best,

can you try increase the resulotion of the disp. map. and be sure your object is closed (optimized). unconnected points may occour "seam look" when applied disp.

Thank you very much to both of you, i 'm gonna try this in few hours ..
Thank you
