Hey, here is a list of all props from version 1.0:
bar_1 bar_stool_2_home bar_stool_4 bar_table bed_1 bed_2 bed_3 bed_4 bed_6 chair_2 chair_3 christmas_tree coffee_table_1 coffee_table_2 cross_stool_home dj_pult_v1 heart_pillow_pink heart_pillow_white hi-fi lightcube_blue lightcube_green1 lightcube_green2 lightcube_pink lightcube_white lightcube_yellow light_1 light_1_blue light_4 light_5 mafon microphone plant_1 plant_2 pole rack_1 rack_2 rack_2_x3 rack_3 rack_3_x3 sofa_1 sofa_2 sofa_3 sofa_4 sofa_5 sofa_6 sunbed sunbed_2 table_2 tv_1 vedro
And the extra ones:
bar_stool_1
bar_stool_2
bar_stool_2_poses
bar_stool_3
cross_stool_poses
door_1
door_2
light_2
luster_1
mattress_1
pan_1
shell_1
pan_1 is the toilet, shell_1 is the sink. And I think mattress_1 has its mesh deleted since 2.0.
I haven't checked the resources of 2.0 and 2.5 though yet.
here are another two not on the list:
sofa_1_snow
glass_table_black
I am not sure about the last one though but I think it can be placed as well
Thank you AlexRyder and Niblette for this information.
