Brand spanking newbie - Lights
show user profile  jamiegreig
Hi Guys,

Im brand new to this and 3ds max so please be gentle!!

I have rendered my model on autocad and imported it into 3ds max. I have an environment set up and all is working ok but my lights are too dark!!

When i turn the intensity up it make the hot spot too bright but doesnt extend the lights reach (if you know what i mean). I have attached a screen dump of the render to show what i mean!

Can you help????

THanks in advance guys!!

well your going to have to be more specific Jamie.

Tell us what lights your using, what your scenes includes, show us your viewport in max, your current render settings etc. 3ds max has compounding factors which make it almost impossible without a decent amount of information to help. try again.

Ok, a few things here. Im not a lighting expert - but for one thing, use a standard omni light to begin with. Photometric lights should only be used when you know your scene is perfectly to scale and you have used them before lol. I could not explain how to use these lights better then in 3DSMAX's Help > Autodesk 3Ds Max Help > Contents > Lights & Cameras section. I know you have probably heard the above many times before, but seriously 20 minutes reading through these files will save you the next 10 hours of reading through forums - not to menton the basic understand you will get about lighting in max.

I would also consider rendering out yoru scene without the photo image, and then compositing it in later, because your lights will affect the image.

edit* side note, your exposure control can ultimately destroy your image if your using the wrong setting, it can even turn out black. so be careful when mucking around with those settings.

try increasing global lighting slowly, this ramps everything up.

haven't used scanline for a couple of years but i think you need a skylight to give you some diffuse light (place it anywhere, non position specific) then light the object with omnis which have attenuation turned on. put a base beneath your object but make it non renderable (right click>object properties>rendering control.....untick all but renderable) this will give you some contact shdows at the base of your object so it sits better in the scene.

You'de be better off learning mental ray though, it's free and much more powerful.

I might be wrong, but i think that putting the photo in the environment slot isn't the right way to do that. You should put it in the viewport background to use it to line things up, then your environment can be something that might help your lighting situation.
