Transparency problem(s)

Ok I know this type of issues have been raised before... in fact I did raise it myselft earlier but with the new version it does not seem to work anymore.

Basically I have 2 problems :

This is our wounderfull snowmobile :lol: it is not final it is for a prototype.




:shock:
1) This polygon is going to be used as part of an animation when the snowmobile moves. The polygon will be scaled and transformed depending on the speed of the snowmobile. This should be pretty simple. We have a black and white png texture with an alpha channel. I read in another post that I should use Src Blend = Src_Alpha and dst Blend = Inv_Src_Alpha in the pass basic parameters. But you see the result, there is no transparency.

What is wrong?

2) This problem is twofold.

First I would like to make a good looking windshield. Maybe something similar to the GT4 windshield. I can't get the texture to be transparent. How should I do it :?:

Secondly, we need the windshield to be visible from both side. Right now if to look at it from behind, the windshield does not appear. How do I do that? :roll:

BTW lioric could you send me info about the pro version at eric.trudel wendigostudios com


Thanks

1. Do you have the alpha value to other than 0?
Do you have shadows enabled?

2. Set the alpha blend mode (src and dst to alpha) as posted, and use the "opacity" value to a lower value (50 == semitransparent, 0 == totaly transparent)

Set hardware and software culling to NONE

The information was sent to your email account, maybe a spam filter issue on your side, i will resend it

Thanks lioric!

It now works!


The only thing left to fix is the windshield visibility from the rear. Is there a way to force the polygons to be 2 sided ?

The hardware and software culling setting should do it

Are H/S culling options of the Pass Material, set them to NONE
