Indigo Renderer 3.8.2 Beta Release

[CTZn]

I didn't post any error message on purpose because it is not from Indigo render. It only shows this: ''Wondows have spotted a problem and Indigo.exe must close''. This message only shows with Indigo 3.8.0 and further. I'm using Sketchup 2014.

if it is ok for you to share the scene with the Indigo team for debugging purposes, do the following:
launch indigo renderer
from the tools menu, browse to the crashing scene and pack it into a pigs
send the packed scene to support@indigorenderer.com

the team will spot the reason of the crash and tell you what can be done about it.

Alternatively, you can remove one or several objects and/or materials at once from the scene untile the crashing behaviour stops; the cause will be originating from the last removed object/material. Please send feedback in this thread if that second method is successful.

I could do that with pleasure but this happens also with an empty scene. No objects nor materials. I'll try though...

ok, this looks like a serious issue. You may want to try to unistall 3.8, restart your computer andreinstall it when the syztem has settled. I'm short of ideas at the moment, I'm hoping that this issue will get fixed soon for you Antonis.

Never noticed it before with this beta : sky is half white when looking at azimuth 0° with :

- value of sun azimuth for -1° to -179° or 180 to 360°
- Bdir or Bdir MLT
- captured simulation

Tested with camera, aperture diffraction not enabled
Indigo RT / Cindigo - Mac OS 10.9.3
Also in an empty test scene (join)

Thanks for your help

Thanks for the report Patrice.
This issue is fixed for 3.8.3.

I'm having some crashes, on several scenes. It all works fine, sometimes for an hour or more, then I get a 'indigo.exe has stopped working properly' crash and it shuts down...

Nothing in the scenes I haven't used before, so no idea what the problem might be...

Can I send you a pigs. to have a look at?

Sure, send it across.

Rendering with MLT gives me weird results in this scene.

Indigo produces the BEST glitches!

The caterpillar scene gives different kinds of strange artifacts each few version, no idea what black magic is going on here :/

Hi. The glitch is due to an unbeliveable circumstance for max. extinction coefficient, meanwhile the more abstract approximation of step-size was able to "resolve".
For the leaf, that is in fact a surface is not possible use this high value of SSS, works if the absorption gain is reached to near 90 (but for this is intended the double-sided thin material, that don´t use max. extinction.
For carterpillar the problem is an exhauxting value of the SSS uniform spectrum. This spectrum is a physic value (instead of RGB, than is more an abstraction) and the meaning is 1/value meters of "penetrability", after the light extinct; this means that in a distance of 1/4771,0644 meters inside the caterpillar, the light "fall-off" totally (a massive extinction).

So, a value near 90 for the gain of the leaf absorption (better another kind of values/materials) and a RGB spectrum off gain 16 in cartepillar SSS definition. As result for two minutes:

Ha ha, finally fixed after so many years ^^

[Oscar J]

Bout time that scene gets updated me thinks, with double sided thin and stuff.

This should be fixed for next release (3.8.6).

Actually Indigo can cope just fine with a scattering coefficient of 4700 or more. I used 50000 for my head render.
