Re: Simulate sun position and lights/shadows
Hi Emmanuel,
I've just realised why caustics don't render (or appear to render, you'll understand why I said this in a moment) while "Add sunlight" is ticked.
Since the added sunlight is a very distant, bright sphere light, the photons emitted for caustics are being emitted by this source so never reach their destination. That's my theory anyway.
On the subject of ibl and sunsky not reflecting with uber, this one is really puzzling me. Found out the only reason my simple math formula produced ibl and sunsky reflections is, because the values as fractions exceeded zero into minus figures. Your math formula is right, sorry I thought it was due to objects becoming to shiny!
As a test: this.sunflow.parameter("glossyness", (float) 0.0); (very shiny and produces sunsky / ibl reflections) this.sunflow.parameter("glossyness", (float) 0.00000000000000001); (still very shiny but doesn't produce sunsky / ibl reflections)
Have tried many other values and ideas. Any > 0 never reflects.
Really wish I could figure this out! Uber ibl reflections are clearly visible at all logarithmic values in this image.

Re: Simulate sun position and lights/shadows
here's a sample render using gloosy option at the right corner at the Schneider logo, I want to make a straight line of lamp, but cannot make a right choice.
it took me 2 hours to render it at 1400x655, but it's worth. the image produced is very good. I wonder what is the best option to choose since that "advanced render" has too many option? and I don't see any difference
@db4tech : how can you do that sink? is that depend on the obj?

Re: Simulate sun position and lights/shadows
Hi fhoofman,
I didn't notice your question at the bottom of your render!
Its connected with settings found in the .mtl file of pencilart's kitchen sink .obj model. It contains a texture and also settings, that when rendered with the Silk setting, produces the great chrome effect.
Hope that helps answer your question. Sorry for the late reply!

Re: Simulate sun position and lights/shadows
Ralf,
As of version 3.0 this plug-in is obsolete. It's functions have been integrated into the standard version of SH3D. Moreover, the plug-in may cause unwanted behaviour in certain situations when installed in version 3.0 or higher. So, don't expect any development on any version of this plug-in.

Re: Simulate sun position and lights/shadows
Even if I would prefer people use the solution proposed in the version 3.x, the advanced rendering still works with Sweet Home 3D as far as I know. The unwanted behavior that happened with Sweet Home 3D 3.0 was fixed in the version 3.1.
To answer noxx question about his "save and shutdown pc after rendering" button, I'm not sure I have a way to turn off a computer by program, but I understand autosaving in a default file could be nice. The problem with autosaving is that it obliges the developer to manage a list of autosaved files that should be deleted if not used. But how long should be the delay before considering an image is obsolete? Where these images should be stored?... An apparently simple question might in fact bring many questions sometimes.

Re: Simulate sun position and lights/shadows
perhaps:
- it is possilbe to define a save-folder in the rendering menu or setup-menu - it is possible to make snapshots in the rendering menu. each snapshot is rendered, so that i can make more as one rendering-photo over night - every rendering photo has a prefix with date and time eg picture_23062011_120500 i think no picture has the same date and time - its possible to set "shutdown after rendering"

Good ideas, bit i think it's even easier (for the developer). When the Rendering starts, it always starts with an empty picture. When the user interupts the rendering, all the work done is beeing discarded, even the save button remains useless. So, to solve this, the program has to store the state of the interupted rendering, keep the resulting unfinished picture somewhere and also the rendered buckets (areas being rendered so far) that are already done (together with the measurements etc.). this could quite easily done by asking the user to save current state of rendering, creating a zip file of the unfinished picture and a xml file with the specs. I've got a very slow machine here to use as well, and sometimes i really need to stop (or PAUSE!) the rendering, which is impossible. therefore a will NEVER create a movie. i need batch rendering for this. macfrog
