God no. There will be a way around it, its just "I" dont know the answer.
Im sure someone else will, given time for them to find and read your problem.

I 'discover' how to do stuff ONLY when I hit that problem myself.
And I have never dealt with multiple large textures like you are doing.
So Ive never NEEDED to solve this problem, thats why I dont know how.


But back to the issue on hand..

Did you take the ent_clone out as I suggested? It more than doubles memory usage.
And when it is crashing, it IS showing 210 models isnt it?
And were they all with the SAME skin? Or different ones?
How big(roughly) is the MDL file IF it contains the DDS skins?
OR How big(roughly) is each DDS file, and how many are used per model?
