IndigoRT_v4.6.4.tar.gz

Indigo RT for Mac OS X (10.13 - ):
IndigoRT4.6.4.dmg

Changelog:
4.6.4
* Improved specular material to take into account an index of refraction that varies with wavelength, when computing reflection coefficients.
* Fixed environment rendering black in OpenCL.
* Fixed OpenGL preview.

4.6.3
* Added initial support for moving objects without rebuilding everything when GPU rendering.
* Added GeometryChanged dirty flag - just does a full rebuild for now.
* Fixed rebuilding of object tree with new Embree code, when changing object transforms,
* Bumped OIDN version to 1.4.3.
* Added in a scale factor for computing light maps, so that we are computing the weighted average spectral irradiance.
* Added render_env_caustics render option (single dir CPU and GPU only)

4.6.2
* Fixed omnidirectional stereo for rotated cameras.
* Storing tangent_ws for emitter objects, used for getting IES basis.
Is oriented with dp/du from uv set 0, if present.
* Not merging IES emitters on GPU, so that tangent_ws can be used.

4.6.1
* Made omnidirectional stereo spherical rendering work properly with bidir.

Blender 2.93.10 / 3.2 export to => Indigo 4.6.4

default export Environment = Base Emission #CBFFFF Tabulated ... how to convert a Uniform ?

upd (ruined, It was necessary to create a scene from scratch and not open the source, Sorry very hard without step by step tutorials on the blender)

Max contributions still doesnt has effect with "optimise for denoising" active on GPU rendering. This makes nasty blury farflies

Perhaps another error or restriction of the GPU mode



1. GPU Back Side Glass Medium Precedence 9
2. GPU Back Side Glass Medium Precedence 10
3. GPU Back Side Glass Medium Precedence 11

4. BidirMTL Back Side Glass Medium Precedence 9
5. BidirMTL Back Side Glass Medium Precedence 10
6. BidirMTL Back Side Glass Medium Precedence 11


2 and 5 ?!!

Thank you Zelevskiy for the quick reply but...I would like to know if there is a "button" inside the Indigo mask that turns on and off this option! Thanks :)

Glass_Windshield_Coating.igm material bug with BidirMTL mode


Coating layer IOR 1,1000 to 1,0000 (or 1,2000+) eliminates white and black dots

With the value of the IOR 1.1 something incomprehensible occurs

Yeah, finally a sign of life again.
It's nice to see that development isn't completely dead after all.
I had almost given up on it.

I hope that this will now also be the case more regularly again.
Otherwise it would be a real pity for this nice renderer.

Not just "nice", THE BEST! I know how you feel, I had to change main render engine, and feel so ill, like my wife left me. Lol, I'm going crazy...FOR INDIGO!
