Paint Alpha problem

[o_hobbla]

Whenever I render my map, the area where I've used displacement and paint alpha in hammer, just gets textured with a texture I didn't use, it also doesnt have any variation, it just looks like the game substitued a texture that isn't a blend. For example, I use the nature/blendgrassdirt001 and it gets textured with something similar to nature/grassfloor003a. I'm not sure what's wrong, so any help would be appreciated.

i think some of the causes of alpha painting failing is if the map has a leak, or if you don't run rad on it. there could be more, but i think those are the two most common reasons.
displacements can't be used to seal your level btw, so make sure to use world brushes below any that you've used.

^^ bingo

if u do a fast compile u get no alpha texturing jazz. fyi

The leak is also a big issue that can cause many other wierd problems. Always the first thing you check for if your map is fishy.

i'ts vrad that makes the alpha, not vbsp
so you map will be full bright to?

check this with mat_fullbright (if its 1, vrad hasn't run )

and no, if you have a leak, the alpha will be correct :d
but lighting will be darker at some places

Sadly, if you have a leak VRAD still runs and your lighting looks normal, so if you don't check your complile log before you play, you end up with large amounts of "wtf" factor.

If there are errors, water or alpha displacements do not render.

looks not normal, areas where no light is pointed at (behid spotlights for example) will be totaly black, you don't have this without leaks
and totaly it will be much darker too.

It always helps to run vbsp only and check the 'do not start game after compiling' box to catch potential leaks and fix them before you do a true compile. (Which takes considerably longer)

Paste this in a .bat file and replace the <ACCOUNTNAMEHERE> with your steam account and the <MAPNAMEHERE> with your map name. Pauses on errors etc.
