View Full Version : transparency issues (vampire warrior content)
Hey guys! I love browsing these forums but dont post much, but I'm trying to change that. This is my first attempt at a true game spec model. I just started painting the texture and it's got a ways to go, but my problem lies with transparency maps. I am trying to get a torn effect with his cape/cloth bits and have tried applying a black/white image to the out transparency channel of the surface shader I'm using. I've also tried a targa file with an alpha channel applied to a lambert material. The self illuminated surface shader won't let me get any transparency effects, and when I use a lambert, I can get transparency in the area I intend, but it gives me funky transparency all over the model as illustrated in the last image. At the moment I just colored some grey to show where the transparent parts of the cloth will be. Has anyone else encountered this problem, or could I be directed to a tutorial that addresses this issue? I'm desperate! I'm using maya 7. I hope my rambling makes a little sense. Thanks very much for any help you might be able to provide!

I'm pretty sure it's videocard related. I had a similar issue using high quality rendering with transparency in maya awhile ago, and after searching the forums it looks to be a common issue with no resolution(that I could find anyway). The only thing I can think of is assigning a completely different shader to that cloth part that needs an alpha.

Hey, nice model!
Did you try rendering it? Myself uses 3D max and in viewport the transparancy map does not work. I thought that would be normal, so if anyone knows how to fix that i'd be happy to.

Nice Character! I like the color combination :)
I remember I had the same problem a while back but I already forgot how I fixed it...

i could never get my models with alpha maps to appear transparent in the right places in the viewport using maya but it did work when i rendered it. To fix this i saved my textures with the alpha map included with the color as a tga:shrug: try it, it worked for me!
It looks awesome by the way i love the way you painted the skin
I've been trying to make time to work on this at night, but it's been slow going, especially since I broke my tablet pen last week etc...just got a new pen for it so I'm trying to finish the textures for this guy (still have a ton more work to do obviously)...I want to put a ton more detail in there, dirty him up, lots of blood, fix seams...etc. Please feel free to crit my work so far :) !!!

yungimoto: Yes, I agree with you...it's probably my video card, thanks for the heads up! I tried your work around with the different shader for those bits and it works...thanks again.
madmenno: Thanks! I have tried rendering, and it does fix the problem...I just like the look of viewport caps for low poly stuff :)
pongstah: thanks a lot...I think I figured out
psychojohno: Yeah I have achieved the transparency with the tga like you suggested. thanks for the advice and kind words!
