Mohan (pattamp) added a comment to T63978: Grease Pencil - Artifacts in render.

Is this still an issue with the latest driver from here: https://downloadcenter.intel.com/product/81496/Intel-HD-Graphics-4400 ?

After reverting to a previous commit and updating the repo to latest commit I see that problem is solved, may be this is a problem at my end.
but strangely even the official build downloaded from Blender website didnt work, it should be independent of my local files in the repo.

Mohan (pattamp) added a comment to T62871: Move rotate scale not working while in draw mode. .

The optiomal solution would be some type of gizmo, somthing like:

  1. Press a key
  2. Display a gizmo and rotate using mouse or some keys
  3. Draw and
  4. Some key to reset rotation.

Of course, this must be a "virtual" rotation of the viewport, not a change in any object rotation or camera rotation. It would affect only viewport, never in render. I think this could be used not only for grease pencil, but texture paint and other paint modes. Draw some straight lines in vertical is more difficult due arm natural anatomy...always it's easier draw with horizontal movements.

Mohan (pattamp) added a comment to rB0d3501725c97: Fix build with QEX disabled.

Not until these features scheduled to land in master. For all i know this branch will go 'nah we'll use something else instead of QEX` next week and i'll have to build that, and then they change their mind again and i have to build that. Branches are highly experimental and don't have the same support from the platform teams that master has. So unless these features enter codereview and it seems likely that it will land in master requiring these libraries pre-build libs will not be made available.

Mohan (pattamp) added a comment to rB0d3501725c97: Fix build with QEX disabled.

For master on windows i pre-build all libraries for you (you grab them from svn), for this specific branch additional libraries are required which are not available in SVN (and won't be until they are required for master) you either have to turn this functionality off, or build the required libraries your self using the build script in build_files\build_environment\windows\build_deps.cmd however at this point in time there is no support on using this script, if it works for you great! if it doesn't bummer, but i lack the time to help individual users with it.

So far I am able to build blender using master without any issues. For sculpt mode features do I have to do something different please advise.

Mohan (pattamp) added a comment to T63103: GPencil - Soft Eraser consistency.

Yes, maybe 90 degrees is too extreme and the math that handles the eraser gets too early a very low value and removes the point. As you can imagine, we cannot tweak too much the code to solve a very corner case and reduce quality for more general situations.
Try to change the pressure of the brush too.
Not sure what can I do here. Do you think we can close the report?

Mohan (pattamp) added a comment to T63103: GPencil - Soft Eraser consistency.

I have done a small change in commit 127ad4fa4a3f
Now the soft eraser low limit before cull point is lower, but for your example there are more factors to consider.
When you set the angle to 90, the thickness of the stroke in horizontal is minimum thickness beacuse the maximum thickness is 90 degrees (vertical). When you apply the eraser, the thickness is reduced and as the original thickness is very low, the point is culled.
If you want to soft erase these strokes, you can set the Soft Eraser to these parameters:


PS: You can test the changes I have done in tomorrow build or compile the code yourself.

Mohan (pattamp) added a comment to T63103: GPencil - Soft Eraser consistency.

@Mohan (pattamp) I cannot reproduce it.
Really, how you draw the stroke (the brush settings) is not related to how the eraser works, so not sure what you mean. Could you provide a test .blend file?

Mohan (pattamp) claimed T63002: Grease Pencil Occlusion.

Hi there was this problem in earlier versions but now it is fixed by intro of stroke placement option for Grease pencil object.
you can choose 3d space to avoid the problem.
attached is your blend file with stroke placement set to 3d space.
hope this helps.

Rotate Canvas (and flip) is a must in deed and it will implemented in a future but It's not a good desing choice IMO doing this by rotating the objectin draw mode, draw mode is for draw not for manipulating the objects. We need rotate the whole viewport.

It would be good to have them back. In the past i saw some scripts and drivers made to do the exact same thing which is natively built up until now but now suddenly disabled.

This was removed by design. The grease pencil team decided remove this options after doing a review of how it was working. The draw mode is only for drawing, not to move.
See ef66aa2005de for more details.
