Physical Objects Colliding With A River Flow Displacement - Developers

Hi Guys, I haven't had to ask a question in a long time. I made a deserty, duney map with a nice lake and river. I took TopHattWaffle's Tutorial [URL="https://www.youtube.com/watch?v=foViqM4xdfE"]here[/URL] and am pretty good at Hammer now, but it can't really see why this happened: [IMG]http://i.imgur.com/Cr5ofEB.jpg[/IMG] The boat doesn't go through the river flow displacement. I thought it would be an easy fix and to just check these flags... [No Physics Collision] [No Hull Collision] [No Ray Collision]? [IMG]http://i.imgur.com/HZR4xRE.jpg[/IMG] But it's still doing it??? And objects are colliding with the river :'(. I thought this would be really fun to ride a boat down and crash into the side or something like a water slide. My next method was to maybe add "$surfaceprop" "grass" in the .vmt file of the river foam (displacement) so that it would *maybe* make it non collidable but it still does it. This annoying thing has gone far enough and am curious to know if any of you have experienced this before and know how to fix it. Thank you :) .

Anyone at all? I find this a little important. :( I mean I could always remove it and just have a still looking river that still pushes but. I won't have an awesome river v_v.

Well I mean first off, uncheck all those 3 things. Secondly, I don't think water is actually functional with displacements. Just looks pretty in the background or something.

Okay I'll look at it. I thought no one would reply to this o_O. Thanks.

You want your flowing water brush to just be a func_brush with collisions turned off (default setting is toggle), and put a regular water brush underneath it by about 1 unit. The water underneath will catch objects like water and submerge normally, and the flowing water texture tied to a func_brush with Collisions (none) will let everything pass through as if it wasn't there. That's what I did last time I used Top's watersource textures and it worked perfectly fine for me. If you still can't get it to work, private message me your VMF and I'll take a look to see whats going wrong. [Edit] Come to think of it I don't think you can have entity based displacements. I'll have to run a test map or find my old one to see how I got it to work...
