Generation Tools - Generate Grids processes bud doesn't create any mesh. Just does nothing.

Border Nav Mesh Creation Tool gets infinitely stuck at 80% or 90%. It is also unclear what is this function is intended for and I think it is never mentioned in the Modding Documentation:

Generating grids on 1.6.3 causes a crash for me as well, after selecting yes or no on the prompt to remove existing navmesh, crashes regardless of if there is already navmesh on the map or not.

Just to corroborate the above reports on an older version, "Generate Grids" also doesn't work for me on 1.6.1. It doesn't crash, but it doesn't function. I believe 1.6.0 was the last version in which the grids could be generated.

Forwarded to the QA team for further investigation. We will reach out again if we need more information. Thanks for reporting and sorry for any inconvenience!

Generating nav mesh grids still doesn't work after an intermediate update. Border nav mesh creation tool is stuck on 80% so far.

As you might know, we have changed the system with e1.6.1:
Better automatic navigation mesh generation for open field battles.

You can use the system via the Auto Nav Debug Tools. Here's how it works:
  1. Open the Auto Generate Parameter drop-down menu. Set "50" Agent Max Slope.
  2. Open the Auto Nav Debug Tools drop-down menu. Set Grid Size (specifies the edge height of the nav mesh quad). If you set the number too low you'll get too many navmesh faces which is bad for performance. We recommend 7 or 8 for Grid Size.
  3. Optional (recommended) Press the "Generate Region Borders" Button.
  4. Now it's ready. You can click "Generate Grids" button under the Generation Tools drop-down menu.
The "Generate Grids" option can only be used through the above system now. If you push the "Generate Grids" button without any preparation, you may receive an assertion.

Additionally, this only creates grid nav mesh faces in the non-edge places (where the grid would not cross any obstacle). Other parts of the scene must be done manually. This system likewise works best in battle scenes and may not be as useful in village or town scenes.

The original generate grids function (still available in 1.6.0) covered terrain with a sized grid contoured to that terrain. During the construction of worldmaps (as opposed to mission battle maps) it is important to cover the whole map with passable navmesh to avoid crashes during testing in game. That requires navmeshing every slope, not just those traversable by agents in mission scenes. The original 1.6.0 generate grids function was the best way to achieve this. As we are not only using the scene editor to make mission scenes, I'll test it with a 90 Agent Max Slope without pressing the Generate Region Borders button (irrelevant to worldmaps) and report back.

BTW I can't see any mention of the above changes in your modding patch notes for e.1.6.1.

1.6.1 Changes​

Greetings,

As part of the e1.6.1 patch, we made another set of modding-related adjustments. As they don’t all fit within the patch notes, we are sharing a list of the changed classes as well as some additional information here. Make sure to check the patch notes for some additional new adjustments.

Just like the OP notes:

To begin, the 1.6.1 patch introduced the following changes based on community requests:
We also introduced a new documentation page since the OP was created:
Beyond that, we continue to work on:
  • Making languages moddable.
  • Documentation on implementing new flora.
  • Documentation for using models to add attributes to items & determine the exact weapon damage.
  • Making UpgradeXpCost and GetXpValue moddable.
  • Minor faction hero templates being added through XML and storing them in the Clan object directly. Making minor faction hero spawn chance and hero limit values moddable.
  • Other requests (in earlier stages of development).
You can find the more detailed list of changed classes here:

Again, the classes that inherit from these are not specifically mentioned but are still affected by the change of their parent class. We will continue to review the code base as we develop the game and you highlight limitations that you are facing.

Thank you for all your feedback. If you have any questions or would like to make further requests, please discuss them below (or HERE).

@Dejan tried out the above in 1.6.5 with a 16x16 custom worldmap and the editor crashed each time. Crashed with Agent Max Slope set to 90 and if set to 50. Crashed if grid size set to 5 (my preference) or 7 (your recommendation). Crashed if I chose to delete the existing Calradian navmesh or leave it in place. Presumably, it only works on smaller mission scenes?
My virus software now identifies the final part of your crash uploader as malware, stopping it from compressing crash reports and attempting to upload them. So, I compressed one of the crash folders and uploaded it here https://www.mediafire.com/file/unj40qhcvnht2kh/2021-11-23_14.02.49.zip/file

BTW I reverted to 1.6.0 and generated a 5 metre grid for this worldmap the old way. Version hopping is very time consuming.

Oh, thanks a lot! I will note this method and test shortly if it's stable for in-game scenes.

The changes in that thread are only the ones based on direct community feedback. But I only did that with 160/161 and maybe some higher versions - recently I include ALL of the modding related changes in that thread.

Passed it on to QA.

Let us know if it works!
 
tried it on 1.6.3, after setting parameters to the suggested ones, generate grids did nothing, the progress bar popped up for a second then disappeared, and no navmesh was generated. When trying to generate with autogen, it only created a single massive face that covered the entire map. Also tried messing around with the parameters, but nothing seemed to change.
 
Following this up, 1.7.0 the navmesh grid gen still doesn't work, same issue as above, except the generate grids progress bar now stays, consumes resources and takes while, but in the end it still doesn't do anything, just a blank scene with no navmesh at all.
@Dejan would it be possible for us to get the old grid gen back? It was simple but it was quick and (most importantly) it worked, at the moment the only way to efficiently make navmesh on most scenes is to version hop back 5 or 6 versions, which like NPC mentioned takes a while to do.

This is exactly what happened to me on 1.7.0
