Brush distortions when using rotate Created 5 years ago2019-03-28 21:03:38 UTC by al_mam

Hi, I noticed that brushes look distorted after I rotate them.
Single brushes may change its width and height slightly, but it's tolerable.
Grouped brushes keep getting their vertices displaced.Is there a proper way to rotate without distortions?

This is caused by the vertices being off grid. They are moved during the compile to the nearest grid point. You can get around this by using HLFix when you compile, but personally I found this caused issues elsewhere in the map. I would recommend instead that you zoom right in and do the required vertex manipulation yourself.

I see. So the best way is vertex manipulation.
Thanks!

If you are using VHE 3.4 or 3.5 then it rounds all coordinates to integers before compiling. If you want to keep using VHE, then there is a patch made for VHE to make it export precise coordinates to the compiler (know as floating point coordinates). It's called "vluzacn's float enabler" or something like that. Another option would be to use another editor, for example J.A.C.K aka Jackhammer, which is nearly identical to VHE but also prevents the rounding of coords. You also should use vluzacn's compile tools, latest are VHLT 3.4. Then the brushes should in most cases remain the way you made them. You might want to turn them into func_wall or func_detail. In this case HLFix is not needed.

I stand corrected. Thanks Bru-ski

I tend to keep brushwork untransformed and rotate it by turning it into a func_rotating and giving it pitch yaw roll values. Not optimal in terms of resource use, but it works no matter what tools you use.

That's actually something that Archie and I use frequently in The Core. That works wonders and prevents a lot of fiddling

Don't angles work on func_wall too?
It's a very old and useful mapping trick.
