GPencil: Important feature request for Blender 3.3 LTS: Add new option "Forced Intersection" #101087

New Issue

Blender Version
Blender 3.3 LTS

Description
I know I've to post errors only, here in the forums, but I hope my question is ok and will reach the developers faster then posting it on the Right-Click Select website, where such things get lost very fast.

We are working since a year on a childrens series for German Television and use Grease Pencil as a major element. I've already posted some bugs here and am in direct contact with Yiming @ChengduLittleA .

My feature request:
Please add a new rule for Objects and Collections called "Forced Intersection". This would allow us to solve a lot of complex intersection logic. I hope this is not a big deal, but it would improve 3.3 LTS a lot. I hope you accept my feature request, because we plan to use the LTS version up to the end of this production.

If you think there is a better forum than Right-Click Select, to place such posts, then tell me the link please. Please post only links, where we really have a chance to get in contact with developers. Unfortunately I don't see this happen on the Right-Click Select website.

Thank you!
Chris

@ChengduLittleA You decide what to do with this task... do you consider it as Design?

3.3 LTS is already released, and it will only get fixes, not new features. So I am afraid it is too late for that feature in LTS.
Regardless, since we do not handle feature requests in the tracker, I will archive this. Yiming is free to create a design task for that if he wishes.
While things can get buried in Right-Click Select, it seems like you are already in contact with the developer, so pointing him to the topic in RCS should be equivalent to creating a topic here in the tracker.

Hi! I actually encourage this feature to be included with later fixes for 3.3, because it's really a minor improvement and it could make a lot of things easier for complex scenes.

If I were to do a better design for a later version, I probably should separate this one flag into "generate lines", "generate intersections", "cause occlusion" three options for more flexible configuration. But for this time I would just add "force intersection" option in the menu.

Sounds great. Thank you.

Changed status from 'Archived' to: 'Resolved'

Hi! This is resolved with D15978. It's a minor change, so we might be able to get it in for the next corrective release of 3.3.

Thank you a lot, Yiming. This is a great addition for all Grease Pencil users, who are working based on 3d assets.

I'm back from my holidays today and found a bug in 3.3.1 Release Candidate:

The problem seem to be generated by the "No Intersection" collection option. See my file and the video.

Supposedly fixed with 6d879601b7 . If your file works okay then I'll put it into 3.3 maintenance page :D

Thank you. I've no idea how to test it here? Have no possibility to compile. Wait for the next official RC/Stable version update?

@ChengduLittleA We were too late! The fix isn't in the 3.3.1 LTS master. The problem: It's super important and makes a lot of work impossible. I'll have to wait for the daylies... :(
