Bracers do not seem to weight paint correctly

[chalecampb]

Using Luna, and the boots, the method of selecting pose -> shift click the geo -> entering weight paint shows zero weight mode and everything is fine. You can shift+click any bone and it selects it. I did the entire previous section this way, including the boots which are separate geo.

In the bracers something strange happens. I select it, and it doesn’t show zero weights overlay. If I try to weight paint like this, with weight paint mode active, it looks nothing like weight paint mode and nothing changes. Then I hit “A” (just a guess, or trying random things, I happened to notice it – in this context it is select all). This causes the bracers to turn black and be weight paintable, but I can’t select other bones. Even using the dropdown at the top. If I exit entirely, then select a bone, then redo the process I can get back into weight painting the bracer.

I noticed this is also extreeeeemely laggy. Everything else was very smooth, but as soon as I added the bracers, something happened and the framerate drops to seconds per frame. On a 1080ti – this is old, but most everything runs pretty smoothly, it is pretty beefy. Anyway, I think there is something going on with an option or setting or something on the bracers that is making them incompatible with the normal process. This is to be fair, Blender 4.1.1.

After some experimentation, Edge Split was the culprit for lag, and it’s back to smooth again after deleting it. It doesn’t look as nice but it’s workable. It doesn’t change the weight painting mode seen above.

Happy you managed to find a workable solution.
You mention the GPU, 1080ti and it’s old, are you using the latest GPU drivers?

Hi Chalecampb,
Sorry for your tech issues – it’s always a pain in the butt when computers go rogue and try and ruin your day.

As for the lag issues, here are some things you can do to speed it up.

– hide parts you don’t need to see
– disable the subsurfs

– disable the surface deform modifier on the leg guards (this will eat up the speed on an old machine)

– change to solid view (not any of the material views)

As for the weird weight painting issues, I’m not sure I follow along 100% with what’s happening.
It sounds like it may be a bug, but could you screen record the issue.
This will help better diagnose what’s going on.

cheers

Heyas! I did this whole course with a 1070 (updated drivers) in 4.1 and it was pretty smooth. I did use a Blender Studio addon called EasyWeights which, with the shortcut set up on my Quick Favorites menu, allowed me to toggle back and forth from weight paint mode easier/faster than the regular method. Perhaps this might help?

The addon is available from Blender Studio in a zip with a bunch of others. I just unzipped the file and installed the appropriate .py file. For 4.2 it appears to be available via Extensions in Preferences.

Same is happening here. I just stopped weightpainting the braces. They looked reasonably anyhow

For anyone experiencing the bone selection issue in the future: the bracers were be set to paint mask for me, rather than bone selection.

Just click the little bone icon to select them again!
