To the point: when my player reaches the edge of the first scenario, i get the following error message:

Malfunction W1103: Level.WMB Compiled without meshes

I'm using large amounts of MDL meshes to compose a backed textured scenario, and i surround this scenario with invisible blocks for collision detection. I'm keeping the mdl load under 200 Mega and i'm also using old code developed in A6 version (hastly fixed).
I don't understand this malfunction message and i hadn't found out any reference of malfunction messages in any of the online/offline documentation...
I'd appreciate any help, thanks.

Answered in 'blame the manual'. Thanks.

"Create Meshes: A7 Compiles the level in A7 mode, with static meshes rather than polygon based blocks. Required for the A7 light manager, or when shaders are applied to level surfaces. This box should normally always be checked. Level rendering can be greatly sped up by combining block groups to single meshes."

Guess that's the price of being used to an old version only
