I don't quite understand your question.

Hey!
Just a thing, how much do we have to scale down in the scale?
The weapon is just large.

Hey I need help with the hdr lighting thing. I did all the instructions you told us to do but for some reason when I run the map on SFM a red text appears saying "VMPI running in SDK mode but incorrect SDK install detected (error 2)". So I'm not sure what's going on. Can you help me?

Absolutely aces, dude. Thanks!
