Hey guys. some noob q.
if table's static everything's fine of course
but when set to "become dynamic"...

table changes lighting
and player able to go through the mesh

same with the deco boxes in udk's Examplemap

maybe i shouldn't use static mesh?
kactor instead?

the ultimate goal is to make all objects like furniture, hanging curtains, electronics, garbage ect. dynamic.
life in hl2 for example

thank you in advance
sorry. my english is bad
