refraction in wrong direction in octane?

[andi]

Yeah the main problem at the moment is for those scenes you need very small light sources, best would be laser light
But with the actual render engine (searching the tiny lightsource from the camera) it takes a lot of samples to get even lit objects. Its a bit better with pmc, so I made this experiment.
But with the coming bidirectional render engine it should be a lot faster.

I'm eagerly waiting for it.
And please please please Octane developer team give us laser light!!!!


But probably I'm the only one who wants a laser ;_(


ps: @Steveps3 did it work, could you render the scene I attached?

Thanks ycarry, good post from roeland. I should have read it before I opened this thread.
He attached an obj and an mtl file. Can someone tell me how I can open this in octane? I mean I can import the obj file but how can I use the mtl file with it?

update: got it, seems that something went wrong with extracting the zip i guess

[ycarry]

Let Octane use mtl, its the material description linked with an(y) obj file.

Edit: Oops I always type mlt instead mtl...
In mtl file you have materials for scene:
'light' (diffuse, you need to edit blackbody as you want),
'prism' (specular, you need to lower the index and play with dispersion)
'slit' and 'plane'. Note to lower environement...

yeah, thanks ycarry i figured it out. At first I just got the mesh in the node editor with only one connection. It seemed like octane did not import the information from the mtl file. Second time I loaded it everything was there.
