I've tried the fast,default,LDR only compile,and the map is almost perfect except for the cubemap problems(Transparent texture reflects weirdly).
But when it comes to the "full compile both final",the map appears totally awful.It's got extremely dark,and all the lights lose the color,becoming either white or black.Also completely no cubemap for transparent texture.I've gone through some maps with "full compile both final" and they all turn out perfect,except this one.So how to fix it?I'm at the final step.

How many times did you fully compile? For me it tends to only look good the 2nd+ time. Also, on your lights, did you change the HDR color or just the color?

I'm sure I change the "BrightnessHDR" of lights too.
But it appears just the same after 5 full compile both final..
There are some env_smokestack which appears strangely in my map (seemingly every kind of smoke in portal 2 work poor).But after I delete them all it doesn't help.
Also when I run the full compile both final compiled map,I type mat_hdr_enabled 1,then mat_hdr_level 1,and it appears normal,the same as the LDR.After typing mat_hdr_level 2,everything's wrong again.I just can't figure it out.

I start to wonder if it is the problem of my computer.Well I got a MSI Laptop,it's new.But sometimes the screen just goes black,totally black for seconds.Also sometimes the screen goes like,everything on the screen like words,images cast another shadow and appears scary.

I never set the brightnessHDR to anything other than its default (-1 -1 -1 -1 I think), and with the cubemaps, try generating them and seeing how that works. You should be able to find a valve page on cubemaps with a quick google search.

Ah it will be a long story to add something like env_cubemaps...But the point is in my earlier hammered maps,these issues never occur,especially the HDR+LDR compile.

It's not the problem of computers.On my desktop still got problems...
Jeez help~!
