I have a piston moving, with a glass platform on it. When I watch it move while I'm standing behind a glass window, the textures on the glass platform are acting weird. My glass window is a func_detail. Actually two, func_details but ingame they look as one. However, it's where the window is cut in the editor that the problem occours ingame.

Are you with me? Glitchy glass textures when looking through a glass windows. Hope you understand and thanks in advance!

I was able to reproduce this small graphical error. I think it might be because of the number of translucent textures messing up the renderer. I don't know if there is much you can do to fix this. Maybe someone smarter then me can help...?

Could be. A fix for this would be wonderful, but in the worst case maybe I'll just have to live with it.

Could you show a picture? That might help in identifying what's causing the issue.

Absolutely! Just tell me how to show it on this forum and I'll upload it!

Yes, like that. Thanks iWork925!

If I'd like to show a screenshot of my own in the future, how do I do it?

Set the file as an attachment where it says "upload attachment" near the bottom.

EDIT: Or upload it to imgur and use the image tag and link.

Thanks for the tip! If there's no workaround to fix this then all I can do is to hope the player won't notice it once the map gets released.

This is absolutely an renderer bug. Sometimes it helped to seperate the VIS leaf both objects are probably sharing. But it's no 100% solution!

Or how about using a glass model, didnt tested that,

What do you mean?

There are models in Portal 2 as a replacement for a brush with a glass texture. These models are mostly used for a breaking animation, but you can see if using one of these models 'fix' your issue.

Good idea but from what I've seen it doesn't solve the problem. Thanks though.

I also had this issue before only with cube dropper and turning glass into a func_brush fixed that.

func_brush, yes! It works much better now, thank you! Still, perhaps I should only use func_brush where I really need it. Guess it's more expensive than func_detail.

Not really. Of course you should make most brushes that aren't sealing your map a func_detail, but a func_brush isn't expensive at all.
