Issue still exists, tested on AMD. Reported to not occur on nVidia.

Thanks a lot, I didn't remember this issue, 2 people reported it yesterday so I thought it was a new bug :p And they didn't precise if they were using D3D driver.

More players have this issue since we're migrating all clients to Ryzom Core :)

Which graphics cards?
Original comment by Cédric Ochs (Bitbucket: [Cédric OCHS](https://bitbucket.org/Cédric OCHS), ).
Last one was :
Windows 10 x64 Core i5 6600 Intel(R) HD Graphics 530 Driver Intel : 15.40.28.4501 (12/08/2016)
Another one : OpenGL 2.1.0 - Build 8.15.10.2202 / Intel / Intel(R) G45/G43 Express Chipset
Apparently almost users with this issue are using integrated chipsets :(

I found a single bool variable that affects dancing trees (1c290dddef2f), not sure what else it breaks tho ;-)

Great find :-)

Makes sense, so the issue would be that the wind weight channel is getting affected by the lighting normalization.

Tested on my windows laptop, tree doesn't dance anymore, and my rapid tests haven't showed any issue :)
Original report by Jan Boon (Bitbucket: [Jan Boon](https://bitbucket.org/Jan Boon), ).
The Wind Tree vertex program is not taking into account the vertex weights (vertex buffer channel PrimaryColor), causing the entire trees to dance.
Issue does not occur in the old official Ryzom build.
Issue does not occur with the OpenGL driver.
