Stopping Hammer from dividing VisLeafs every 1024 units

How would I go about stopping it from dividing visleafs every 1024 units?

You'd need to edit the renderer source.

why'd you wanna stop it from doing so?

I have my VisLeafs set up perfectly with hints but it keeps dividing them.

This isn't possible. I believe VBSP does it, and the engine wants it.

I haven't tested this but you may be able to control this with the VBSP compile parameters:

-block # #
Control the grid size mins that vbsp chops the level on.
-blocks # # # #
Enter the mins and maxs for the grid size vbsp uses.

It is something I've been meaning to test/investigate.

You could try placing a func_viscluster throughout the map (or surrounding all of your map; you could make your own custom visgroup so you can disable/enable it at will (so it doesn't get in the way. Remember to turn it back on if you do make a visgroup, or it won't be rendered in the map).

That won't work. Visclusters don't stop the compiler from creating leaf boundaries; it just tells them that certain leaves can always see each other. I'm guessing Jasa up there is trying to prevent the visible "seams" that certain leaf boundaries produce in dark areas?

It is the -blocks command. Doing this is not a problem.

I think 1024 is too small also. Cuts the vis really complex. this is not the old days either where lots of viscuts are necessary for optimization. Specifically speaking outdoor maps...

1024 isn't small. it's pretty good measure. indoors it's like two appartment lenghts. outdoors much like the side lenght of a regular house or property. there you go outdoor levels. which btw in general uses more displacements than brushes. also the lightmapper tesselates the brushes anyway which results in the same grid like structure. i don't see any point in complaining.
