Re: spectral rendering

Can you explain the picture?
From my point of view often when i use dispersion, many of the colours are missing and i get just R,G and B.

Re: Custom Normals do not work in render

Did you use the daily built?
Did you read what it says?
See the sentence starting with "Custom Normals will not work ...."

Re: "Running Out" of samples.

The halt condition must be a multiple for "Samples per pass" number shown in Sampler panel. The value is usually 1 so it doesn't matter but in the case of out-of-core rendering is important and > 1. This should be handled internally in the input parsing of the form. I can not input letter, yet i sh...

Re: spectral rendering

, or reduce all the spectral data to RGB values and fall back on three component rendering again. They suggest exactly what i said above. They want render a R,G and B Sample and each with the frequency dependent Material values. Then they sum it together. I think that is also what they did with POV...

Re: spectral rendering

Having said that, "Spectral Render" may also be implemented in several ways with more or less Quality and speed.
Because you can render just 3 Frequencies, or you could render 20. (Nature renders unlimited many). :-)

Re: "Running Out" of samples.

Here i think Tiled Mode is even faster (even though it should be slower).
The only Problem is that Tiled Mode does NOT support light Tracing.
In all other points including "Responsiveness", Tiled-Mode is better.
Did you try just NOT to use the "Out of core rendering"?

Re: Rendering with multiple Instances of Blender also rendering multiple at the same time using virtual Desktops

You mean this: Blender-Market . Its a sort of "Render-Que". Really Blender does NOT have a Render-Que? I mean Cinema 4D has it since years, Poser also ... I wonder that this is not Part of Blender. Its something that is really missing in Blender. I will take a look on this. Besides that ... it does ...

Re: "Running Out" of samples.

I also have that curtain-effect. It starts down there and slowly wanders up until the picture is ready - or ruined depending on the scene.

I guess it comes from the "out of core rendering". In Tiled-Mode its not there.

Re: spectral rendering

My hint for the developers: For Spectral rendering there will be the need to rework all materials for the frequency dependent attributes. If you take the constants from the POV-Include files, that i have linked above, you can reach a very natural spectral result. Even to the level that several ISO-L...

Re: spectral rendering

There is possibly a sort of hint, how any of the Blender-Renderers can be made to render spectral. It was done with POV-Ray already 2013 and the results were interesting. If you want to give it a try take a look at the Links below. For this you will need: 1. to make several renders of the same scene...
