Fix Dota 2 map in SFM

[See-Bow]

Hi guys, (sorry for my english)

I am looking for some solution for my problem for 3 days. I followed this guide: [URL="http://steamcommunity.com/sharedfiles/filedetails/?id=313936526"]http://steamcommunity.com/sharedfiles/filedetails/?id=313936526[/URL]
But when I load any downloaded Dota 2 map, SFM crashes (without any message).
I can turn off "World brush models", which allows me to see the map without crashing, but when I turn it on again it crashes.

Some guy said me that I must rewrite all "[B]MultiBlend[/B]" to "[B]VertexLitGeneric[/B]" in ....\game\Dota 2\materials\blends folder. After that it works fine but look f*cking bad [URL="http://prntscr.com/5l8auh"]http://prntscr.com/5l8auh[/URL] (and ground is too light...)

I can't found some solution for this problem all around the internet.
Guys, please, can anyome help me with that?
Thanks for any help... :)
