A stupid question: Which edition do you have? This does not change scaling in WED, but region clipping is a Pro feature.

Thanks for the video, I now finally see what you mean. It seems to happen when you scale a region extremely large in one direction. It doesn't happen here, but might be dependent on some scale setting. We'll fix that.

But it seems that neither I nor other people can confirm your other region problems. Regions are supported in all editions, with exception of the region_set command, which is Pro only. But region_find and region_check work in all versions with both WED created and script created regions.

Please check again. If you can't find the problem yourself, please contact Support and send them your project where WED-inserted regions don't work. They'll look into that.

Using A8 commercial, but not region_set.
What you cant see in the video is that this "side effect" gets faster and stronger with every additional time you scale (eg pick an arrow) - not dependent on how long each individual scaling process is. Don't know if this helps you find the error

I will try again, although I already did what I could - started with a blank level and so on. Anything I could possibly do wrong, for example when compiling the map?

Thanks for your time

Nope... have a look at my simple project, it just wont work:
www.sajeth.com/temp.cd.rar

Use C to check the current region, R to create a temporary region. All source files included.

Can no one confirm/deny this?

Thanks for the project - we have not yet looked into it, but will check it out in the next days.

I think Sajeth builds his level using "Build BSP Map", this does not work for me, too. I have to select "Update Entities", otherwise my regions won't get into the wmb file.

Danke - das hat funktioniert!
