Cycles XML, light node does not react to transform (it was ok before migration to graph/node* node parsing). Let me know if this is a bug or it is by design.
See attached sample XML.
<cycles> <transform translate="0 0 -4"><camera type="perspective" /></transform> <integrator max_volume_bounce="0" method="branched_path" sample_all_lights_direct="true" sample_all_lights_indirect="true"/> <background heterogeneous_volume="false" volume_sampling_method="equiangular" ><scatter_volume name="scatter" color="0.8, 0.8, 0.8" density="0.3" /><connect from="scatter volume" to="output volume" /></background> <shader name="point_shader"><emission name="emission" color="0.8 0.1 0.1" strength="100" /><connect from="emission emission" to="output surface" /></shader> <state shader="point_shader"><light type="point" co="0 0 0" size="0.01" /></state> <!-- Light does not react to transform node --> <transform translate="0 0.5 0.0"> <state shader="point_shader"><light type="point" co="0 0 0" size="0.01" /></state> </transform> </cycles>
