Grayscale maps for lighting gels in Octane

[ajr0717]

We went over this, before, and I cant remember our answer but no post has a title with this significance

There is a very expansive technique to be applied to lighting in poser by using greyscale based lighting gels to serve as the alpha value to "let-light-through"

We said that in order to do a "blinds effect" in Octane, where it looks like light it coming through horizontal or vertical blinds, you have to find a geometry that imitates those beams of separation, because thats what llets light slip through (beacuse Octane is so realistic,. and we thumbed that up)

So what can we do do achieve light on a gradient such as the funky effect achieved in the promo photos for those RDNA files?

Thank you all for your time

I don't think you can easily get these effects in Octane. You could try some sort of custom IES file (unsure what the IES format is or if you could specify the patterns you have shown), or you could pass the light through some semi-transparent specular material surface, but unsure how effective that would be.

Could you pleeeeeeeeeeease tell me what you mean by "what the IES format is" or what an IES "format" is

[ajr0717]

I would like to know so i could help you to answer me

IES lighting is covered at http://render.otoy.com/manuals/Poser/?page_id=104.

Thank you I read it
If I just plug the black white patterned files we're talking about into the distribution pin will that succeed in making all the blackbody emission in the white areas of the distrubtion map very strong and the blackbody emission in the very gray areas of the distribution map very dull?

I doubt it - since the "distribution" pin requires an IES file which is going to be some sort of encoding of your pattern. But I know nothing about the IES file format - sorry - it's something you will need to investigate. As indicated above, I don't think this will be simple to reproduce in Octane.

It makes alot of sense. Thanks.

Success! Is this what you were looking for?



Also works in color!

Woah, very cool effect: how did you end up solving the problem??
