previewing program

is there a program that can let you see what you are doing in hammer but real time rendering. i think i have seen something that does this but maybe be not.

It would be nice not to have to compile when your making little changes to a map.

try out the Crafty Object Viewer by Nem.

If it’s just lighting you want, look under the views on the 3D section.

That only works in L4D/L4D2’s hammer, it crashes otherwise

Umm… It works in my hammer.

It works if you use Episode 2 as setting.

Crafty Object Viewer by Nem. didnt work that well for me went all crazy.
