what does skylight portal means??

[bakbek]

in a nuttshell its a like a regular light but it gets its parameters from the scene environment ( that's why all the parameters r grayed in the modifier tab ) and it needs a real openning in order to work into a closed geomtry.

main use for it is to push some more environment light into an entirior scene.

Bakbek.

but for some reason, if i trun on skylight portal, and turn the GI environment multiplier to 30, it's still dark as hell, can see anything..help!!!

I think you need to give us some more info on what you are doing... Some screenshots of your scene for example.

well there's no picture because u cant see a thing even if i post it up, it's toatlly black!!, i did what the tut on vray.info says, get a hdri and put it in the environment slot and crank the multiplier to 30, vray light, turn on skylight portal, , GI is on, and everything is black, and take 30 min to render!!..help!!

maybe flipside means a screenshot of your viewports and the scene you are trying to render, not the render itself.

i dont no how to make screen shots...lol..anyways.. i know what the problem is now, and i still cant fix it, the porble mis that i got a boolean object, and the car i am rendering is in the boolean object....if i dont render with the boolean thing ,everything is fine, but if i do, nothing appears and everything is dark??? is this a bug???

ok, to do a screenshot, there is a button on ur keyboard, typically on the right side, top that is named "prt sc" or something along those lines, typically near the pause button.

hit it, and then go into ur favorite image app, photoshop or mspaint even, hit paste and save.

print screen simple as can be.

Skylight portals are used to get more of the envoronment light into an interior. Are you doing an interior?
Is your hdri in the override environment slot in vray's environment options, or did you put it into a vraymaterial slot?

If it is an interior, is your window tiny compared to the whole room? Is teh portal inside the window and pointed in the right direction?

Yes, I meant a screenshot of your max viewports, so we can see what your scene looks like, how everything is placed etc...

Hmm.... Your camera is inside a wall\object?
You accidentally turned off gi calculations and have disabled all other lightsources?

You are using an expired demo?

Dunno....
