hi all,

i have a cloud of polys with an image mapped onto the transparency channel of each. this gives me a lofi way of making some styalised cloud clusters (see attached image)

now, to fly through the clouds without polygons popping i thought i'd just add a "distance to camera" gradient into the transparancy channel as well.

hmmmmmm, problem is it overrides the other trans map.

should i be using nodes? (of which i have very limited knowledge) or is there something obvious i should be doing?

thanks for any help

n.

Whats the blending mode set to? Also is each cloud a separate object? You might be able to do something with object dissolve as well.

Don't think you need to switch to surface node editor for this (unless you need to animate the gradient parameters). Guess you can do it in layer system in several ways. You might want to try any of these options:

First Layer: clouds texture (Normal)
Second Layer: gradient (Normal)

or

First Layer: gradient (PShop Screen)
Second Layer: clouds texture (Normal)

or

First Layer: gradient (Alpha)
Second Layer: Value 100%
Third Layer: clouds texture (Alpha)
Fourth Layer: Value 100%

or

First Layer: gradient/clouds texture (Alpha)
Second Layer: Value 100%
Third Layer: clouds texture/gradient (Normal)

Very nice cloud of polys, btw! maybe you already are using this trick but mblur could help you to achieve a more smoky look.
