Brecht Van Lommel (brecht) added a comment to T50975: Cycles: Light sampling threshold inadvertently clamps negative lamps.

So far we've supported negative light strengths, though in practice I would suggest to never use it. So if we want remove it at some point that's fine with me, but maybe better for 2.8.

Brecht Van Lommel (brecht) added a comment to T50974: Normal map tangent computation is slow.

Developer note: the way Cycles accesses coordinates through RNA is slower than it could be, and moving the computation into Blender would deduplicate code and make it a bit faster. However I think the main performance issue is in the algorithms in mikktspace, as generating tangents for Blender Internal is also very slow.

Brecht Van Lommel (brecht) closed T50993: Background images and Load UI as "Archived".

Backgrounds image assignments are part of the UI, since they set for each 3D view and not for the scene. That then also means loading a different UI loses the image.

Brecht Van Lommel (brecht) closed T50987: UV editor, UV unwrap operation misbehaving between different Render Modes as "Archived".

Yes, this is not a bug though the behavior is somewhat confusing. The Correct Aspect option works based on the image texture assigned to the mesh and visible in the 3D viewport, which is done through the material. For Cycles, the image shown in the image editor is decoupled from that.

Note that even though you have a Radeon HD 6730M graphics card, the backtrace points to a crash in the Intel i965 graphics driver. The Radeon should be faster and not suffer from this bug, but the operating system might not be configured to use it.

Brecht Van Lommel (brecht) added a comment to T50969: Cycles doesn't work correctly on my machine, causes Blender to crash to desktop and UI elements to disappear..

Two things to check:

  • Did you modify the Blender 2.78c addons folder in some way? This kind of looks like it has the Cycles addon from an earlier version, like T50893. Maybe fully uninstalling Blender and reinstalling helps.
  • There is a bug in some auto installed NVidia drivers, reinstalling the driver manually can solve the issue, see T50650.

Brecht Van Lommel (brecht) added a comment to rB2d3c44389ab7: Fix OpenCL warnings about doubles on some platforms..

We already have many other float constants throughout the code and the rule to add the f postfix. Adding device specific code here does not abstract that away. This code was just not properly following a rule we have.

The more code we can share between CPU/CUDA/OpenCL the better, every device specific code we add can get out of sync and makes it more work to maintain, so I rather not do this. PI is PI anyway regardless of which header defines it.

Ok, I think we have really different ideas about UI design here, I don't think we're going to agree about what the best solution. I strongly prefer names that indicate purpose rather implementation, orthogonality of functionality whenever reasonably possible, and find image texture color space compatibility between .blend files created with different configs to be absolutely required.

Brecht Van Lommel (brecht) added a comment to D2547: Color Management: Allow selection of the OCIO configuration in the User Preferences.

I think the OpenColorIO design and existing implementations and configurations are clear, color spaces and transforms are not the same thing. Being able to specify an absolute color space rather than a transform relative to some other color space is critical for making exchanging of image files between applications work.

Brecht Van Lommel (brecht) added a comment to D2547: Color Management: Allow selection of the OCIO configuration in the User Preferences.

In *this* case, the EOTF specifically identifies the transfer function, which is what it happens to be doing. It is relevant again as the actual transform and the view are applying precisely that.

When I flip over to the wide gamut, the EOTF for the view transform would change to what it identifies, as well as remain as a transform for curves, colour pickers, gradients, etc.

Except in the case of BT.709 primaries based files with linear encodings, where the chromaticities component would be required, but not the OETF / EOTF. Hence the division.

Brecht Van Lommel (brecht) added a comment to D2547: Color Management: Allow selection of the OCIO configuration in the User Preferences.

This particular issue is the one I spoke of regarding roles. If we implement roles across Blender properly, using the ones enforced by ociocheck, this becomes a non-issue. That is, the data role in Filmic versus the data role in the current would both point to equivalent non-colour transform definitions.

Brecht Van Lommel (brecht) added a comment to D2547: Color Management: Allow selection of the OCIO configuration in the User Preferences.

2.8 seems like the right release to introduce wide gamut, and indeed we can do some intermediate now in 2.79 so we can already start testing that. I'm hoping we can some compatibility when we officially introduce wide gamut, maybe automatically converting between scene linear color spaces. It's going to break a lot of things, importers/exports, shaders, scripts, .. . But that's for another time to discuss.

What are you suggesting the path is then:

  • Break compatibility when changing to a better reference space
  • Add a second filmic configuration when changing to a better reference space
  • ... ?

Brecht Van Lommel (brecht) added a comment to D2547: Color Management: Allow selection of the OCIO configuration in the User Preferences.

If there's a different scene linear and reference space, then I can see we need a separate configuration. However, currently filmic still uses the same Rec.709 reference space?

Brecht Van Lommel (brecht) added a comment to D2547: Color Management: Allow selection of the OCIO configuration in the User Preferences.

For custom OCIO configurations, maybe the datafiles/colormanagement/ folder could contain subfolders for each, and it would simply use the folder name in the UI. No need to set up anything up in the user preferences, Blender would automatically detect this.

For the tangent, we'd need to add support for that in the GLSL system indeed. Maybe refractor the code to move that computation out of the renderers as much as possible and make it a new customdata layer for Blender itself.

I didn't expect you'd actually implement the BSDF in GLSL, but that's great. For the other nodes we have a quite poor approximation, this is better than that. The GLSL shader seems to be working ok on macOS.

The "View offset is locked" message is shown for two operations:

  • View Pan with shift/control + scroll
  • View Dolly with shift + control + middle mouse drag

Brecht Van Lommel (brecht) added a comment to T50658: Voronoi texture cells biased towards mapping coordinates.

Perhaps changing the order to this helps? So there is no repetition in the rows or columns.
