Doesn't show distance numbers in Blender 4.3 and slower. #23

Open Foulvertex opened 1 week ago

Foulvertex commented 1 week ago

Distance numbers aren't shown in the Blender 4.3. Also 4.2 extension branch have significantly slower overlay drawing.

Jrome90 commented 1 week ago

I am not having any issues with Blender 4.3 with the 4.2 extension branch. Is Distance Text toggled on under HUD Settings? image

Foulvertex commented 1 week ago

Found the issue. Display units HUD was broken because scene distance units were set to "Adaptive". And slowdown is caused by some other add-on. Sorry for the inconvenience.

Foulvertex commented 1 week ago

UPD: Slowdowns still happen with ALL other add-ons disabled inside Blender even after restart. However, If I move/rename add-ons folder there are no slowdowns at all. I don't get why it's happening.

Are there any errors when it happens? Would you be able to upload a short clip showing the slowdown?

Foulvertex commented 1 week ago

Sure!

This is clean Blender with only FastLoop enabled and no add-ons folder existing:

This one is the same clean Blender with only FastLoop enabled but add-ons folder is present, but they are all disabled.

It may seem not much, but on heaver objects the lag is very noticeable, and honestly I have zero clue how disabled add-ons might affect anything.

Only errors in cosole is spam of this regardless of addons or not:

"Push constants have a minimum supported size of 128 bytes, however the constants added so far already reach 184 bytes. Consider using UBO."

If you unzip an addon and put the folder into your ""blender addon folder"", your addon folder looks like this for example. Screenshot 2024-11-24 at 11 09 56 pm When you startup Blender, the new folder and files will be build to help blender. Means blender goes over everything in the ""blender addon folder"" to see new stuff (addons) & read the files it generated. Means even with disabled addons, blender have seen all the pycache files... at startup. And maybe this could slow down a bit. Also you are in a modal mode tools, that is always a bit tricky with dense mesh.

Hope that helps

But it happens even after a few mins of Blender being idle, also CPU usage is 0% before I use FastLoop, so I don't know. Also, the lag is noticeable on a simple cube too.

Jrome90 commented 1 week ago

I wish I knew what the problem is. Here is Fast Loop with 4.3.0 With addons: image

The drawing speed seems reasonable. That is until I down into the denser geo.

I suspected it might be connected to Edge Flow add-on, and I was right. After I commented the code in get_edge_flow_version() I got my performance back. Maybe it doesn't like too many add-on folders with many modules, etc?

Regardless, thank you so much for this wonderful add-on, it works on very dense meshes and can't live without it.

You found the issue? That's wonderful! I will work on fixing that ASAP. Thanks!

Just pushed an update that will cache the Set Flow version so that it doesn't loop through all addons every frame. I cannot believe that I never thought to do that. Sorry!

Foulvertex commented 1 week ago

Thank you very much for creating and supporting this gem!

P.S. Looking at the code, if the user doesn't have Edge Flow add-on installed, doesn't this function will try to find it every frame? I'm not a coder or anything though.

Yes, it will check every frame. But it is now cached and won't affect performance.

So where to find the updated version if not here!? :-)
