Re: Simulate sun position and lights/shadows
wowwwwwwwwww... first off congratulations on this amazing soft and these unbelievable render plugs. I found this program a week ago, I´m making a 3d animation and I needed something exactly like this to make the scenaries. Also very useful the tip of the memory tunning with the txt file. So Puybaret, db4tech and all the ones that help to develop this great soft congratulations. I will be uploading the video when I finish it and of course will give the correspondant credit to sweet home 3d and it´s people. see you

Re: Simulate sun position and lights/shadows
By the way I forgot to mention that from version 1.6, the sphere of the bulb lights coming from the updated SH3F files have a diameter equal to the maximum value between their width and their depth (so it will be 10 cm by default). The sphere of the other lights have a diameter equal to 6.5 cm that allows to use almost all the lights of the available SH3F files as light sources (see image bellow), but may change how your images will look compared to the previous versions of the plug-in. If this last diameter is too large, you always have the option to import again the given light from 3D models page with the import furniture wizard, then you add one of the updated bulb lights in the imported light and change the size of the light bulb.

Re: Simulate sun position and lights/shadows
You're welcome Emmanuel!
I really hope the extra features and rendering tweaks help many users by allowing even more photo realism. I too greatly look forward to seeing users renders in the gallery section, using the new features that version 1.6 brings!
Here are a couple of examples to let users see what is now possible with the new Silk setting.
Firstly Pencilart's kitchen sink and units (thank you again Pencilart!) using the glossy setting. As a guide, this is all the original Advanced renderer was capable of producing.
Now here is the same scene, rendered using the Silk setting which (apart from being able to produce glossy and diffused surfaces) can also render real (diffused or shiny) chrome.
The Silk setting does take a bit longer to render scenes, because it uses a far more advanced shader. So only choose this setting if your scene contains different levels of diffuse surfaces and/or chrome. If not the Glossy setting will be faster.
If anyone has any questions (or comments) please feel free to ask(or post)
Right I really must stop and get some sleep, just wanted to post these first to help.

Re: Simulate sun position and lights/shadows
I just fixed a few small bugs in the Advanced rendering plug-in and updated the last plug-in file accordingly. Sorry for the problem. No one is perfect.

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!
