train project 2 questions

[jimd]

Hi guys working on a train project

and I have 2 questions that maybe you can help with

 

first question smoke

when i export out as a jpg or tga I get smoke in the finale render ( test mov jpg has smoke)

when I export out as a movie I get no smoke however when I place an image such as the stars in the background I get my smoke

( test mov has smoke because of star png background )

is that normal for movie export or do i have to turn something on

 

2nd question models

do you guys mdl to scale

say something is 20 feet do you mdl 20 feet

I've been doing what feels comfortable is there a rule ?

 

thanks

Perhaps you have alpha buffer option ON when rendering to a mov? The smoke may not be included in the alpha channel? (turn it OFF?)

 

OR...perhaps A:M requires some background to composite with the smoke. I suspect it wouldn't render to a TGA with alpha channel On and no background either.

Yep I tried the alpha on and off for movies

And it did not work that's how I ended up placing an image

 

I might try doing a different project to test the smoke

 

Note it dose show up in the quick render

I'm not sure it's a rule but I've always felt that if the Hash programmer's gave us the grid and ruler tools to make models fit nicely into their math why not use them. So far the only thing I've modeled that isn't full size is my sky dome which is 3 miles (4.8 km) in diameter.

 

I'm curious as to what causes a scale other than full to feel more comfortable to you.

I'll echo Rodger...I find it easier to stay consistent if I model to scale.

Well when the rotoscope seems out of scale

This train started out like that so I just left it that way

Then it got me thinking I kinda just model then stretch to fit

Yikes! The obsessive nit-picker in my head just had a minor coronary.

 

You may find this rotoscope tutorial useful.

Thank you !

great site you have, loaded with good info (it's been booked mark )

and I promise from now on I will try not to guess an stretch
