Hi, @Domarion !

Yes, this issue is related to slow update of ray-tracing acceleration structure. Engine uses heuristics to predict, if object is movable or not, to build TLAS once during the loading. For same reason animated characters/items are excluded from RT, as it just too slow.

There are about 2 cases when engine fails to predict, if Vob is static or not: portal to Jarkendar and the hidden wall controlled by this lamp.

For now this issue is "wontfix" - as we need to build solution for RT+animation and then just put this lamp and wall into animated bucket (tilt heuristics)
