* Updated Technical Reference with some render settings.
* Fixed problem with exit portals and new sun/sky model.
* Fixed crash with ISL with circular binding of variables.
* Fixed bug with Phong resulting in fireflies at exponents near zero.
* Fixed issue where GPU path tracing wouldn't work with empty scenes.
* Fixed possible crash bug with OpenCL GPU acceleration
* Fixed GPU acceleration rendering some materials e.g. phong too darkly in some cases.
* Added optimisation for GPU acceleration: avoiding some traces.
* Fixed reporting of CUDA device name.
* Added check that the number of materials specified for the model is the same as required by the geometry (mesh).
* Fixed 'x' button in material editor crashing Indigo.

What, is this possible now? I probably missed some update... With 2.x, setting specular reflexion caused albedo to be black

Hi Etienne,
It still is black - when spec. reflectivity is enabled, the diffuse albedo is disabled. It just renders more efficiently now.

Hey Ono,

light layer bug is still there... it would be nice if we could get some feedback about that.
I could keep bumping it here, but I would be very happy if I could get any statement about that issue of you.
Pleasepleaseplease.

Seems like Glare is only squashing bugs since the last stable build, not much that you can call a new feature to introduce bugs and stability issues...

This version should even run smoother then the last stable :D

I use the latest beta builds in my commercial projects since ever, if I find a show-stopper I fall-back to last used version and keep working...

Stable release is definitely on the way, we've been focusing on fixes and documentation in the last weeks :)

bright region around sun is narrower.
There may be something wrong around this

Hi CTZn,
What you are seeing there is bokeh, basically. The sun is blurred due to being out of focus.

Ah yes the object is 2cm high indeed. Weird, I never noticed this effect earlier, glad it's a false flag also.

Hello

I just upgrade my linux build, THX !!! :)

but still bug with large tri.
I don't use very last nvidia 295.20 but 190.10. Maybe you can try this .igs to see if it's linux issue

please have a look to it

thx

Hey, thanks for making the sky brighter - I was really noticing that the shadows are typically too dark.

I have a possibly new bug report that would be great to have fixed:
When you render a material ID or alpha render, if you have a material that uses a PNG with transparency (eg. a leaf of a tree) - The alpha render or ID render will not respect the transparency/null material. So instead of the render showing the outline of the clipped leaf, you get a render showing all the leaves as rectangles.

This makes these render modes somewhat useless if your scene contains vegetation (which all of mine typically do) and adds a fair bit of extra post pro work.

Hopefully, it's an easy fix. :)

Thanks!

The source of the problem is that those triangles are so thin, they become 1-dimensional lines (which cannot really be intersected by any ray).

The correct way to handle those kinds of situations looks like this (sorry for the poor diagram):

just tested with 295.51 on my windows machine and having some issues here too, but less noticeable then in your pictures.
I remember that Indigo had (speed) problems with very long "needle" polygones... the knife tool could be a quick workaround here for the moment.

**EDIT**
Well explained Lyc...
Funny fact here is that Indigo in CPU mode renders fine here ^^
