Indigo Renderer 3.4.1

[CTZn]

*dribbles and bump*

I don't know if it is possible to have the glare put on the sun layer.

[CTZn]

and follow-up:

..so I guess that with more spp the sun-lit part and the others will get more and more homogeneous?

Yes. They will converge to the same values.

I've added scatter and parametric surface test scenes if anyone wants to have a play with it.

Would it be possible to set scattering to a "non overlapping mode" of the meshes?
Could be hard to calculate for complex objects, so perhaps by using bounding box... or a second (generated?!) simplified mesh?

Hi Zom-B,
This will definitely be improved, to avoid overlapping as much as possible.

Either with this version or 3.4.2 - apperture diffration no longer works.

It works fine in 3.4

Confirmed. Though it still renders inside the max plugin, just incorrectly.

On a side note, when you click the "aperture diffraction" checkbox in indigo, does it use post process or "real" diffraction? - It would be nice to have an option =) I'm not sure if it's just my PC but post process takes a huge amount of time to compute (time for an upgrade?) lol

Only what you set it to in the original scene

* Added experimental scatter support.

How about texture based scattering?
By a simple BW mask you could control where stuff should be scattered and where not!
This would be a simple and artist friendly way of control and made that whole thing usable for advanced stuff like the attached example...

Good idea, makes it simple for exporters to harness the scattering power taking the responsibility away from the host app (some really suck at scattering).

Would be amazing! It would definitely lighten up modeling and speed up the export process. The only drawback would be not being able to adjust it from within the host app, but I suppose once Indigo becomes integrated into host app it wouldn't be a problem.

Hi all, a very quick question - apologies if this has already been answered in a previous 'update' thread, but I couldn't find anything...

I'm still running Indigo v3.0.10 - the only update I really care about is being able to render faster, particularly being able to use GPU acceleration with render modes other than simple PT ( I tend to use BiMLT)

So my, question, is this possible yet? I have a little more time now to get to grips with the changes made in a newer version, but theres probably little point if the basic speed of rendering is likely to remain unchanged.

No still only PT available for GPU, but there have been quite some optimizationsa and speedups done for that mode since your super old 3.0.10 version O.o

BiDir mode has been enhanced quite nicely during some of the latest updates
