Indigo Renderer 4.0.41 Beta Release

Post by OnoSendai » Wed Jul 27, 2016 6:30 am

This is a Beta release.
If you spot any bugs or problems, please make a post about them in this thread.
Thanks!

Indigo for Windows 64-bit:
IndigoRenderer_x64_4.0.41_Setup.exe

Indigo for Linux 64-bit:
IndigoRenderer_x64_v4.0.41.tar.gz

Indigo for Mac OS X (10.7 - ):
IndigoRenderer4.0.41.dmg


Indigo RT for Windows 64-bit:
IndigoRT_x64_4.0.41_Setup.exe

Indigo RT for Linux 64-bit:
IndigoRT_x64_v4.0.41.tar.gz

Indigo RT for Mac OS X (10.7 - ):
IndigoRT4.0.41.dmg

Changelog:
4.0.41
* GPU PT: Fixed problem with Phong nkdata materials as children of non-basic materials.
* GPU PT: Fixed some bugs that sometimes caused crashes in realtime changes with GPU enabled.
* GPU PT: Changing e.g. the substrate material of a coating will correctly trigger a GPU rebuild.
* Made it so that texture exponent -> texture roughness conversion is only effectively applied if roughness param is actually edited in UI.
* Improved texture exponent -> texture roughness conversion.
* Made some scene nodes (render settings and tonemapping currently) be serialised and saved in IGI files.
This allows tonemapping settings, whitepoint, curves etc.. to be saved and loaded with the IGI.
* Bumped IGI format version to 8.
* Made colour curves work with loaded images.
* Made light layer setting updates work for loaded images.
* Added some tooltips for material control.
* Changed label from 'Emission' to 'Emission Mult'.
* Increased blend param step, also made max value 1.0.

Great!

Is motion blur still planned for the OpenCL path tracer?

Quick question about the exponent-roughness switch: does exponent still work, i.e. for exporters? Are there more scene description changes planned? Don't want to go too far in the wrong direction ;)

Also, is there any kind of list of 'minimum features' that exporters should implement? Or a common way of exposing things?

Ono big thank's! this release is productive

I tested 67 pieces of materials (metals category) in the GPU mode correspond to 100% quality, with the exception of gold, despite the large amount of time to render is a lot of noise:

noteworthy that gold sample 750 / 555 / 333 ... rendered in the GPU mode is excellent, and with the pure gold that something is wrong

Yeah, you can still export exponent params from exporters. They will be loaded and render as normal. It's only when you change one of the exponent params in the UI that they are converted to roughness.

If you are targeting Indigo 4 then you should prefer to display and export roughness though.

Regarding minimum features, we don't really have a strict minimum feature set, it depends on the application and what will be important to the users.

Whoops, fixed for next release.

I fixed this mat on the MatDB, try re-downloading it.

This one runs out of mem due to too many nk mats :)

This material looks different than the image on the MatDB in 3.8 as well.

Ono, Thanks for clarifying
also were minor errors with color lighting materials:

I think, that after editing and saving in .41 material can't be opened, I get error:

Code: Select all

Error: Failed to parse material: Failed to find expected element 'diffuse_albedo_spectrum'. (In element 'scenedata / material / phong'): <phong> <diffuse_albedo> <constant> <rgb> <rgb>0.850003814755 0.850003...
Exponent group is removed in mat definition but after adding it manually material works:

Code: Select all

<exponent>
		<constant>5000</constant>
</exponent>
