invalid scene node / geom / something data for math calcs with all scenes on some devices

[antont]

getting these on some linux boxes on all scenes, and never with any scenes on other similar boxes. both with nvidia drivers and without.

visual symptomps are e.g. empty scene or some objects showing, but as black

as suggested, checked places that call this in the Tundra code -- these seemed like the relevant in OgreRenderingModule:

./Core/OgreRenderingModule/EC_Mesh.cpp: 220 : return float3x4::FromTRS(node->getPosition(), node->getOrientation(), node->getScale()); 239 : float3x4 tm = float3x4::FromTRS(node->_getDerivedPosition(), node->_getDerivedOrientation(), node->_getDerivedScale()); 1359 : float3x4 localToWorld = float3x4::FromTRS(node->_getDerivedPosition(), node->_getDerivedOrientation(), node->_getDerivedScale());

./Core/OgreRenderingModule/EC_Placeable.cpp: 815 : SetTransform(float3x4::FromTRS(pos, orientation, scale)); 874 : SetWorldTransform(float3x4::FromTRS(pos, orientation, scale));

./Core/OgreRenderingModule/OgreWorld.cpp: 229 : float3x4 localToWorld = float3x4::FromTRS(node->_getDerivedPosition(), node->_getDerivedOrientation(), node->_getDerivedScale());

Can you output the data that comes out of node->_getDerivedPosition(), node->_getDerivedOrientation(), node->_getDerivedScale() on those systems?

Below is a traceback, comes from sound listener, which has scale 0.

Got a hint from Jarkko, this can be due to locale -- finnish numeric local breaking txml reading. We confirm now still.. INDEED! Doing this helped, no warnings, and materials show \o/

LC_NUMERIC=C ./Tundra --file scenes/EntityMoveTest/scene.txml --server

without this got when system setting was: LC_NUMERIC=fi_FI.UTF-8

I added a unit test to MathGeoLib to test that Quat::FromString works properly independent of the used locale. See here https://github.com/juj/MathGeoLib/commit/06a3d00ff1362150b88ad2cf45b600747c3791e1 The test passes successfully on my system. Perhaps the issue is somewhere in Tundra code?

closing as is a duplicate, would be good to fix still
