TAR Auto Radar with Instances

[MatteR]

Hi, my map is getting closer and closer to playtesting, but as the complexity grows I've started moving segments out into instances to make Hammer easier to work with. What I've noticed, however, is that when using TAR - I lose all radar info for the instances.

For example in the screenshot below, I've circled an area containing a house (which is actually still in the map below... Kept it for safe keeping) but because it's an func_instance, TAR no longer has the tar_ visgroup data.

Is there any way around this? Or would I be subjected to manually editing the radar images?

 

Thanks a lot.

I usually just generate the radar by temporarily copying the brushwork from the instance vmf into the map vmf. Then generate radar and delete afterwards.
