Error reading grass [worldspace] [x,y] Unknown grass data file format

[Nemo92]

I have currently problems with generating grass lods with DynDOLOD.

When i click on Start this error message pop up:

[02:15] [DoObjectLOD] <Notice: [Tamriel] Gathering grass data for object LOD>
[03:11] Error reading grass Tamriel [-1,-3] <Unknown grass data file format>

When i fixed a worldspace another error with another cooridinate pops up afterwards.

The only grass mod i use is Verdant.

Is there a way to solve this problem?

The log.txt is in the attachment.

Hello good evening!

So I'm getting Range Check Errors when I attempt to run Dyndolod. Specifically: "Error: Error reading grass Tamriel [-1,-10] Range check Error"
I am not sure if its a grass problem or versioning problem. The dyndolod exceptions page lists "error reading grass" and "range check error" as separate errors, but here they are both combined in the same error. I am also not 100% if the versions of all my dyndolod components match up correctly, since I am on Skyrim 1.6.64. 
The first time I had an error that said "Error reading grass Tamriel [-1,-8] Range check Error". I followed the instructions on the Dyndolod exceptions page for error reading grass, which is to delete the .CGID grass cache for that cell. I did that, and then I got the same error for [-1,-9], then again for [-1,-10]. This makes me think the problem is not isolated to just one bit of grass (both of these cells are in the mountains directly between Secundas Kiss and Bleak Falls Barrow). I have successfully generated a grass precache with No Grass in Objects. I have also successfully ran xLodGen64, TexGen64, and ACMOS road generator.

For grass, I am using QW's Grass Patch 2 which is a combination of Cathedral 3D Pine Grass, Origins of the Forest, and Folkvangr.

My current Dyndolod set up is as follows:
Skyrim Version: 1.6.64

Dyndolod Resources SE- 3.00

Is my DynDolod setup correctly, or do I have some kind of grass problem?
Thank you for your help <3

See https://dyndolod.info/Official-DynDOLOD-Support-Forum#Post-Logs which DynDOLOD log and debug to log to also upload.

The DynDOLOD_SSE.ini shows that you changed GrassGID=gid, which means you instruct DynDOLOD to read the *.gid files in the load order and not the *.cgid files.
So, deleting or recreating *.cgid is not going to change anything. The reason it reports different cells/files is because the order of the files are being read is not guaranteed to be the same every time. of As explained in https://dyndolod.info/Messages/Exceptions#Error-reading-grass-worldspace-x-y, the vanilla *.gid files are of the wrong format and do not work. There should be no need to rename *.cgid to *.gid anymore or to set GrassGID=gid now that NGIO is available for newer runtime versions.

Everything below has nothing to do with reading of grass cache files:

There is no Skyrim runtime version 1.6.64, do you mean 1.6.640?

The runtime version is only important to choose the correct version of DLL plugins. There is only one version of the DynDOLOD Standalone, as there is only one version xEdit/xLODGen. See https://dyndolod.info/Downloads and https://dyndolod.info/Help/Large-Reference-Bugs-Workarounds

There are two versions of DynDOLOD DLL NG and Scripts:
DynDOLOD DLL NG 1.6.11xx and Scripts 3.00 for runtimes 1.6.1130 and newer/higher
DynDOLOD DLL NG and Scripts 3.00 for all older/lower Skyrim VR 1.4.15 and Skyrim SE/AE 1.5.x and 1.6.x runtimes.

So, if the runtime version is 1.6.640, it is lower than 1.6.11xx. You need to use DynDOLOD DLL NG and Scripts 3.00 - DynDOLOD.DLL NG plugin for Skyrim SE/AE 1.5.x/1.6.x (not 1.6.1130 and not 1.6.1170) and VR 1.4.15. Otherwise there should be an error message from SKSE when starting the game.

Ok, So it sounds like my Dyndolod is setup correctly and its a grass error.

So what this means is that in Dyndolod_SSE.ini, I need to change "GrassGID=gid" to "GrassGID=cgid", is that correct?

Yes you should keep the default setting GrassGID=cgid, since that is the file ending of the grass cache files NGIO generates.

There is no reason to rename cgid files to gid now that NGIO is available for 1.6.x runtimes.

Mm i don't remember ever changing anything in there that the step guide didnt tell me to change... 
But anyways, it worked! Dyndolod completed successfully! Thank you for your help!

hello i was following a guide to make grass cache and everything went fine. When i run Dyndolod i got a Range check error and i dont know what to do. arnimaDUPLICATE003 is a mod - the reach and it seems that a grass mesh is missing. maybe because of the grass cache is overwriting it? idk. there is also an image from the debug log attached (the file was too big). any help is nice

Error reading grass [worldspace] [x,y]
Delete the *.CGID file. Load the game, open console and type "cow Tamriel x y" without the quotes and the values for x and y from the *.CGID filename to load directly into the cell. No Objects In Grass should then generate the file anew, which hopefully can then be read next time DynDOLOD is run to generate LOD.

https://dyndolod.info/Messages/Exceptions#Error-reading-grass-worldspace-x-y
There is a problem reading a grass cache *.CGID/*.GID file. It is probably corrupted and should be regenerated. It could also be in the vanilla Skyrim LE format (Skyrim SE vanilla BSA ship with the Skyrim LE format, hence the vanilla grass cache files do not work).
Find the file in the ..\Data\Grass\ folder and delete it.
The filename is of the form [worldspace]X[x]Y[y].CGID with leading zeros to pad up to 3 digits.
Start the game, open console with ~ and type cow [worldspace] [x] [y] to load into the worldspace and cell so that No Grass In Objects generates the *.CGID file on-demand.

Delete ..\Grass\arnimaDUPLICATE003x0044y0016.cgid
Start game, open console and enter cow arnimaDUPLICATE003 44 16 to generate the cgid file anew.
Generate LOD.

When using Dyndolod normally, I have no issues. However, I decided to attempt to generate a grass cache and when attempting to use dyndolod afterwards (texgen worked as expected with grass billboards), I get this error.

I'm running DynDOLOD through Mod Organizer 2 on Linux and many times it will just get stuck and stop doing anything. It's not that the program crashes it just stops spitting anything out to the console. Sometimes it does work and when it does it finishes in a little over 1 hour, but most of the time it just stops around "Creating texture atlas" for Tamriel. I've left it on overnight a few times and woken up to it still being stuck in the same spot. Looking at htop I can see that sometimes it will still be utilizing the CPU and the processes will still be in a running state but I just don't see anything happening. This doesn't happen for TexGen or xLODGen, both of which I can just setup and walk away and they will be finished when I come back. Does anyone know anything that I can do to make it more consistently work?

It seems like the few times that I have gotten it to work it has been when I am actively doing other stuff on the computer. It hasn't worked if I just walk away.

Some details that might help: I'm on Manjaro Linux. I'm running MO2 through Lutris with feral gamemode enabled. I have a very high end computer so I am confident it is not just taking forever just because of my hardware. I'm using GE-Proton9-23. I'm using DynDOLOD 3 Alpha 182 with the DynDOLOD DLL NG and Scripts installed and using the settings recommended by the STEP guide minus grass lods for now.

Relevant log files, though the program doesn't usually crash so I don't know how useful these will be.

My bad I think that was from when I tried to run it with grass LODs but I didn't have a grass cache set up. I've been spending all day today trying to get appropriate logs but the program just keeps stalling freeezing. I let it run last night when I went to bad and it got most of the way through it but when I woke up the UI was frozen and I didn't have any plugins in the output directory so I don't think it finished.

Some things I've tried: limiting the the program to only be able to use 12 cores (I have 16 physical cores), limiting the number of concurrent processes in the ini to 1 with MaxLODGen=1, limiting the number of threads to 4 in the ini with LODGenThreadSplit=4, but still no luck it always freezes or stalls around the time that it starts generating texture atlas for tamriel. I wish I could give you more relevant logs but it seems like it only writes them when the program either experiences a fatal error that causes it to crash or it finishes, neither of which are happening for me it's just getting stuck.

[PumpkinHat]

I finally fixed it by rebooting my computer and disabling my bashed patch. I'm not sure which one fixed it but I would guess the bashed patch was the problem since it says in the console to disable it if you have problems I just didn't think the problems I was having, DynDOLOD just getting stuck, were caused by the bashed patch. If anyone else encounters this issue make sure to disable the bashed patch before you generate.
