Indigo Renderer 3.8.0 Beta Release

[OnoSendai]

Hi everyone,
We are pleased to release the first Indigo beta in the 3.8 series. This will be a free upgrade for all Indigo 3.x customers.

We have a ton of changes in this beta release. The big ones however are the large speed increases, which, while depending on the scene, may be 80% or more, and the introduction of arch glass, which should be extremely useful, especially for arch viz renders.


Please bear in mind that this is a beta release - don't do work on a deadline with this version as there may be crashes etc..

Arch glass support is experimental, and we will probably be tweaking and improving it.

You can read a little more about some of the changes in this release in these blog posts:

I'll go into more detail on some of the changes (Winter/ISL changes and participating media shader changes) in a later forum post.

Changelog:

3.8.0
* Render speed in general should be significantly faster, especially for bidir and on simpler scenes.
* Added 'arch glass' (architectural glass) option for specular materials.
* Rendering of partial transparency (blends with null) is now handled much better.
* Optimised material rendering speed, especially phong material rendering speed
* Loading of large IGS files is now much faster.
* Improved the RGB spectrum editor - Supports RGB, HSV and hexadecimal RGB values.
* Improved light layer UI.
* Added ozone to atmosphere model, for more realistic twilight skies.
* Added MieCumulusPhaseFunction (mie_cumulus).
* Greatly improved rendering of heterogeneous media.
* Heterogeneous media: Removed step_size, added max_extinction_coeff instead.
* Optimised rendering speed of old sky model.
* Texture and shader editor now show material and channel name in title
* Added voronoiDist and randomCellShade functions to ISL_stdlib.txt
* Added IPv6 support to the network rendering.
* Disabled glass accel support
* Stopped building Indigo for 32-bit Linux.

Winter (ISL) changes:
* Shader eval functions, and some others, now require an 'env' argument of type 'opaque'. Old shaders will be automagically fixed up.
* Improved int->real type coercion.
* Improved type coercion for div expressions.
* Made unary minus work for vectors, added op_unary_minus for operator overloading.
* Added new form of if function: 'if then else'. Replaces old if(,,) form.
* Added proving of being well-defined.
* General code-gen improvements for faster shaders.
* Faster compilation of shaders.

Known issues that we will fix soon:

* Possible crash with double-sided thin material and bidir
* shadow catcher pass may render incorrectly

It does seem a lot faster!

Awesome update, the speedups are sweet like honey!

My MLT optimisations narrowly missed being included in this release, the next should have it

Does Not work for XP

The Point of the entry in procedure inet_pton is not found in library DLL WS2_32.dll.

Hi Prof4D.

thanks for reporting and sorry about the inconvenience. We'll fix that in one of the next beta releases.

Cheers,
Yves

wow, I'll see into bugging the PC owner from now on ¡

there is a bug with sub surface scattering (same old scene for testing):

There is a mirror on the right. The pot with scatter material is as you see.

I'm getting a segmentation fault error in console mode, when Indigo tries to save the image. the render runs fine up until the first save attempt. I have it set to save once every hour. this is on OSX 10.9

Good Work !

Problem: Online Material Database don't find any materials.

Hi,

where can I find arch. glass? Thanks.

[Zom-B]

where can I find arch. glass? Thanks.

In the Indigo Gui once you picked a specular material, there is a checkbox for it under "transparency". The Feature isn't available in the exporters at the moment, they'll need a update first...

I'm getting an unexplained crash (Indigo has stopped working...) on booting up a simple scene. Will try with other scenes.

Just wanted to confirm I tried the exact same scene and followed the same steps with the stable version and it works with no problem. The segmentation fault crash only happens with this new version.

edit: now all is working as expected - I have a feeling this was more OSX Mavericks -related. it's turning out to be one of the buggiest new OS's I have ever used... super frustrating.

Curious bug with Indigo RT 3.8 (bidir, mlt ...)
Not on 3.6

Just a plan and a street lamp
Can send the simple test scene.
