need help with a tube of liquid (smax)

[CountZero]

hi again, making a tube with liquid in it (blood of course...) but i got some problems first of it doesn't render very well, the transparent tube absorbs light too much and cast a shadow on the liquid which i'd like to remove. also is there any way of making the object representing the liquid acctually filled (volymetric something)?
thanks in advise

For realistic liquid simulation you need a plugin... like Realflow.
Anyway, you can do interesting stuff with only max.

I think you have to use raytrace material for the glass tube, and remember if you add reflection it depends of the environment to look right.

Hope it helps pal.

Well if the tube is absorbing light, make it more transparent.

[CountZero]

thanks fabrizzio, i'll try that.

zytrex, the problem is that the liquid which is a cylinder within the tube gets shadowed no matter what transparency i set :/

[CountZero]

gah!! i change from standard to raytrace, and i get a much better result, but when i copy the object, the copy isn't rendered in the same way as the original D: it's driving me insane, they should be identical, right !?!

[CountZero]

the tube on the left is the copy (havn't found a good setting for the reflection of the tube yet, but why do they turn up different???)

I think u want to set the material as two sided?

[CountZero]

no i don't think i need 3-sided, i have one tube with an inside and an outside and then a cylinder for the blood with just an outside. anyway, here's a problem... i can't get the tube to be transparent, though it shows the blood cylinder... but as you can see on the left picture below there is one item that isn't rendered. the tube with the cylinder is completely solid though i set their transparency almost maxed. anyone know what could be the problem?

or asking the question in another way... if you were going to make a bottle of wine, what material settings would you choose, on the bottle and the liquid, to get a good result? would you model the inside of the bottle?

I think that u need to change the IOR of the two materials for the glass it shoud be 1.56 and for the blood it should be 1.33(water) or whatever..

as for the shadow problem, use raytraced shadows for the light u use to cast a transparent shadow..

I hope it helps...

Advices:
To get the glass look:

First: Hey boy! Take off that orange background! when you set up glass you've got to keep things clear. Use a white background by now.

Second: Please Increase specularity!!! 300 or more! and set the glossiness to 60 about (you can play with it...)

Of course, add a raytrace or a refract/reflect map in the reflection channel, value: about 50...

Keep us updated Countzero!
We're gonna do it (actually, you)!

Hope it helps!
