Yes, absolutely sure with the revision and I get the exact same backtrace.

Thanks for the fast response @Bastien Montagne (mont29), but rB00dc0666b3fe doesn't actually prevent the crash for me - unless I am missing something here. I did a complete fresh build at rB00dc0666b3fe just to be sure. The above mentioned steps are still valid to reproduce the crash here.

We ran into this problem multiple times at work (Windows machines) and had no clue what was going on, so thanks @kevin deguisne (iscream) for the hint!

Ralf Hölzemer (cheleb) added a comment to T48481: Extrusion Along Incorrect Local Axes.

Why would this apply to X and Y, but not Z?

May 21 2016, 12:58 PM · BF Blender
Ralf Hölzemer (cheleb) added a comment to T48481: Extrusion Along Incorrect Local Axes.

this is because the extrude operator automatically sets the second transform orientation (double tapping) to normal mode, which is a sensible thing to do for extrusions. You can verify this by looking at the status message on the left in the viewport header after double tapping an axis key.

thanks for the review!
I tried to address your comments by rearranging the logic into a more readable form. Now there is a clear separation by shading type and I also got rid of the second switch by nm->space.

Ralf Hölzemer (cheleb) updated the diff for D1775: Better approximation of transparent BSDFs in GLSL.

Another change based on wrong observation/assumtion that the result is always fully saturated. This would give wrong colors with full transparency (white color). That itself wasn't very noticable with a single Transparent BSDF, but mixing a Transparent BSDF with another shader would show the color skewing.
Also tweaked the power of the incoming hsv value influence on the results hsv value to more closely match the change in brightness.

Ralf Hölzemer (cheleb) updated the diff for D1775: Better approximation of transparent BSDFs in GLSL.

Updated Glass- and Refraction shaders to use the new method. Had to shuffle around some code to make it work. Otherwise the glsl compiler would complain about the missing node_bsdf_transparent function.

Ralf Hölzemer (cheleb) added a comment to D1775: Better approximation of transparent BSDFs in GLSL.

Sure. After analysing the rendered results of the BSDF, i realized that the outcome is mostly controlled by the value and the saturation of the incoming color in HSV space.

Ralf Hölzemer (cheleb) added a comment to D1763: FIX: "Selected" view mode in outliner.

The reason for that change for me was the need to really only see selected objects. I use it currently on a big project at work. It is a representation whats going on inside blender and very useful for many operators that depend on selection state and also for python debugging purposes. An alternative solution maybe would be to make it more clear of whats selected in the outliner in general by changing how selection state is represented. The current method/theme does have some drawbacks im some cases - like the camera icon.


That being said, I would still say the active/selected views should stay because you can see at a glance of whats going on without scolling through a big scenetree in all other modes.
