Vilem Duha (pildanovak) added a comment to T53593: rake brush spacing wrong since revision 076616898bff.

There should be a bugfix release soon and this bug literally brakes sculpting.

Peeked in the code and it's quite clear what happens.
the check if there's enough distance for estimating rake brush orientation is resetting, so small steps aren't possible.
The check should happen only on the beginning of the stroke, now it happens after every brush application...
Is that clear?

Hi, this fixes the problem but introduces another bug, which is even more serious, and that is with scaling of the spacing property.
I will report that separately right now...

Vilem Duha (pildanovak) added a comment to T52914: Add a new Selection tab.

I would like to implement several selection tools for blender, including this panel. I just have to find some way to fund my time.
My ideas are these:

  • add 'select similar' to right click menu. Enables selecting objects by similarity to any property(I actually have this as an python operator)
  • add logical operators to all selection tools - add, remove, intersect, inverse intersect , so selections can be built in many more clever ways
  • implement several more select similar operators( I have this as an addon too) -vertex count -island vertex count ( these 2 are good for finding and re-assigning instances in imported files or where you accidentaly make copies instead of instances) -vertex colors
    • many more, just name it

I managed to get rid of the audio message and it's got nothing to do with the startup stopping(not crashing)

Vilem Duha (pildanovak) added a comment to T45463: Cycles bake - high-> lowpoly bake triangle orientation is mixed for texture coords in shader normals..

just uploaded a file for the above comment - you can see half a triangle has an artifact, it's probably because of the triangulation of both objects acting over each other. Here the artifact is again quite subtle, but I guess it's visible how the coords are rotated. again, add triangulate to the object which gets baked from to fix the artifact and see the difference

Vilem Duha (pildanovak) added a comment to T45463: Cycles bake - high-> lowpoly bake triangle orientation is mixed for texture coords in shader normals..

Upadte - this also happens with highpoly objects, so even if the lowpoly object has triangulate, it can still happen.
When both objects have triangulate, then it's ok.

Just a comment - it looks very similar to other artifacts you can get in other bugs, but it's not a duplicate. All somehow manage to mix something up, but they are all different by the specific conditions in which they happen.

Ok, so I did more tests. And, filepath_raw actually doesn't work either. It doesn't erase the image changes, but the image doesn't get saved WITH the changes... at least in the testfile I sent. I totally understand it's good to lower the number of bugs before the release, but doing it this way isn't nice to users who spend time reporting the bugs....
should I report a new one?

Vilem Duha (pildanovak) added a comment to T43985: Setting filepath of an image reloads it, which breaks all kind of generated content (including baking)..

This could be called at least misleading, or very confusing behavior. The reloading is really not clear at all because it's not in documentation of the filepath prop, only mentioned in filepath_raw.... Also, what sense does it have to load an image which does not exist as a black image? shouldn't it try to load the image and when the file does not exist, then not do anything? Or, when the image path was same before, and I set the path 'to be sure' in the script, then this also has no logic at all..
But at least It's now clear to me...

Just to reply to your comment, not sure if it's a typo, but we talk about setting filepath, not name... although I didn't test if renaming does the same.

Thanks Sergey,
I hope you didn't investigate too deeply, this is old stuff and now I am using a script instead.
Actually, it's working well with images, for scenes where I operate with 50+ characters, I can't imagine having it as a mesh with similar resolution (images about 8k X 8k) .
One of the works I did with it was actually printed, the others I do on CNC like this one-

Vilem Duha (pildanovak) added a comment to D808: Adaptive stopping and sample distribution for Cycles.

I had this idea:
For product and many other shots, I often have lot's of white background, very simple light, and what I need is to clean the noise in the shadow.
I understand, that with strong light, there might be strong noise also in the area where everything is lit, but it is out of range for eye. This noise would come out only if color correcting.
Would it be possible to allow the algorithm to ignore noise in white areas? or does it allready do so?

Vilem Duha (pildanovak) added a comment to T38401: Metropolis Sampling.

PGTART -
actually noise in cycles tends to be more visible in out of focus areas, but especially when something is really close to the camera. Also, post processing filter will never be able to achieve a good quality defocus for complex scenes. Believe me, I tried to squeeze the maximum of it in some projects, and while it is a great feature, it will never ever look close to what cycles does. Remember too, that actually in cycles, you don't get a consistent zbuffer because of the sampling, and you need this for the postprocessing. This exact feature you describe is in blender internal, which enables you lower sample numbers in out-of focus and fast-motion areas, exactly for the reason you write, but that counts with the postpro. Sorry if getting off-topic here.
