I'm making a new map and I have a little problem. I have a wall as func_brush. This wall will move in the game. There is also goo on the ground. Also, behind the wall there are items...

The items get reflected in the goo and the wall doesn't and this should be reverse. So if the wall is there, items do not reflect in the goo and the wall does and when the wall is gone the items should reflect.

Is there a way how to achieve this?

Also check out in the func_brush properties and make sure that "Render Fast Reflections" is set to Yes

Is it possible to reflect prop_dynamics in goo?

On a related note, all my goo water textures don't reflect prop_dynamics. (I always use the first texture of the model browser if you search for "toxic", because this water texture doesn't have the annoying square borders)

I get the opposite effect: everything that is not an entity using a model or not a prop_dynamic does not show up in goo reflections.

Well, I'm not in front of my computer right now... but I guess you're referring to "toxicslime002a" maybe? I'll have to check out into the .vmt later and let you know but, if you can, meanwhile go check into the .vmt if there's a line like so:

"$reflectentities" 1

(or maybe this line has a "0" value)

If not, try to add it saving the texture with a different name, and select it in hammer in your map...

Tell me if it makes some difference.

Which water texture are you using?

Thank you anyway.

Tnx for the help, setting "Render Fast Reflections" to Yes fixed my problem

Glad to hear!

Yep it's working now. I have set onlyreflectmarkedentities to 0 and added reflectentities 1.
however, now it has a noticeable small lagging on my PC, which can't honestly be called bad, what leads me to the conclusion that I should name this texture "toxicslimeExpensive" and only use it in special occasions.

Thank you anyway.

Yeap, I'm afraid this water has become expensive by reflecting all entities... Anyway, indeed you could make some use of that param "$onlyreflectmarkedentities" instead marking only those entities you want to be reflected, this way it's you who decides the most convenient balance between performance / reflection...

EDIT: Addition to all above said: sometimes building cubemaps solves many bugs in reflections, please note!
